Hi there! :) My name is Cherie. You may have noticed me around the forums this week. I signed up a year ago but haven't really gotten involved on this site until now. I've been working on an '84 Coupe DeVille project since early 2012. It was my first car, and for all intents and purposes it's pretty much like a child to me -- me and my Caddy are inseparable. I've dragged it from Arizona to Utah and now to California. I couldn't work on it while I was in AZ and UT because I was in college (for engineering if that explains my lack of spare time). Now that I'm out of college, I'm finally working on it! I am more proud of this project than you will ever know.

I recently replaced the timing components and water pump among a semi-long list of other things. I HAVE to have this car running by the end of July, after which is must depart my friend's driveway, and since I don't yet have a driveway of my own, I have to have it running and registered so that I can park it at my apartment complex (registration is another hurdle I'm going to face.. more details on that dilemma later). I need all the positive energy and ambition as possible TO. GET. THIS. DONE!! :D

In order to get it running, I have to finish putting the rest of the components back onto the front of the engine (pulleys, compressor, radiator, etc), and then I have to reconnect the distributor and spark plug wires (both new), re-time everything, put new gasoline, change the oil, change the transmission fluid, and probably a handful of other things I'm forgetting right now. Since I'm waiting for my parts to come in from McMaster (I'm devising my own harmonic balancer installer), I thought that today I can go over and wash my Caddy, clean up some of the rust (Scotts Valley, CA is humid!!) and possibly sand and prime the areas that the naval jelly can't really get.

I've been occasionally updating a project website: http://1984coupedeville.wordpress.com/

But soon the project website will be moved to my own domain and server by August 2013 (so don't pay attention to this site 'til then): http://nebulosity.cc/

I'll try to post more updates on this thread as my project progresses. :)

I hope to get to know you guys, and all of your projects and posts and replies seriously keep me moving forward with energy on my own project!

Wish me luck!!! Time to work a miracle!

Wow, the first? I'm not entirely surprised, but I know these forums have been on the web for a long time. :)


So was the old timing chain broke?

Nope. My chain outlived the cam sprocket (teeth were badly stripped) and so my car did this lovely thing where it wouldn't start, but the camshaft would turn "INTERMITTENTLY," as the mechanics said. Everyone I asked about this said my camshaft was broken, or the mechanics who reported this to me didn't know what they were talking about. Turns out that hand-cranking the engine caused the chain to slip, making the camshaft movement look intermittent, and cranking the engine with the key moved the camshaft just fine (the chain somehow stuck with the momentum imparted by the starter), but because the timing was all screwed up, it wouldn't start. It was a problem that baffled me for six months before I sucked it up and tore the front of the engine off to see what the hell was going on. In the end, you can see it for yourself in this video:

Terrible, huh! That was a really sad and dinky cam sprocket. :(

A real gearhead that speaks fluent English . . .

That's what 10 years of undergraduate and graduate school will do to you, lol. I suffered through grading too many papers written by junior year engineering students who couldn't even spell properly.


Cherie, hang out in here, the Lounge and in the Engines threads. (The sticky posts at the top of each forum threads page can have some good info hidden there.)

Trust me, this will be my constant, online home for the next few weeks and probably the next few months as well. There are so many posts here on the forums that every day I spend digging through threads, I learn new things. I'll keep looking too. :)

YES YES YES YES times a million. Especially considering even finding a place for your hand in this engine compartment fully loaded with parts is hard to manage. I could fit three of me in here!

Haha, yup! Sometimes when I'm working inside there, I'm sitting down, and no one ever sees me in there, so when my friend walks by and I pop up, occasionally he still laughs because it's unusual for people to disappear inside engine compartments. It's not the first time I've fit myself inside an engine compartment though.. I managed to get cozy inside my friends Cherokee WITH the engine block and most of its parts still in there. See? (photo attached).

Judging by the first pic, looks like you have some different pinstripping going on on the header and hood. I've never seen a timing chain do that, only rumors.

nebulosity
07-09-13, 07:05 PM
Yep, it's got pinstripes on the hood and the sides of the body. Is it not common?

And yeah, no one else thought that it was the cam sprocket that had stripped. It was an issue that really baffled me for a long time. I hope anyone else in the future who is seeing the strange crank-no-start behavior I saw will find my post to know that it could be a stripped cam sprocket. I sure didn't find a single thing online when I spent weeks searching and asking several mechanic friends. :/ I post about everything on my project website in hopes of saving someone the confusion and time I've spent.

The pin stripe in the middle raised header part isnt stock that I know of.

07-09-13, 07:14 PM
Interesting. The car has been in my family since 1994, and the paint and exterior haven't been changed since then (except for a few spots I primed to prevent further rust, lol), so if it was added, it was added by the older couple who were the first owners in the '80's and early 90's. Now that I know it's not common, I'll definitely keep an eye out for similar Caddies to see what other people have. Thanks for pointing that out. :) When I restore the paint, I plan to add the same exact pin-striping that has been on it for as long as I've known the car. I'm really quite fond of it. :)

You've come to the right place. I've dabbled in many automotive ventures over the years and have joined lots of related websites as a result. I firmly believe that the people in this forum - particularly this RWD section - are the best you will find anywhere. If you can't get help here, you can't get it anywhere.

Good luck with your project. You need to get that thing out of your friend's driveway and enjoy driving it - and let others enjoy seeing a classic on the road.

Also, once you get a factory service manual, you'll burn that haynes manual in the next bonfire. I know that thing has got to be making you mad with the lack of info. You'll be reading the service manual by the bed and on the toilet, its pretty damn cool. Every single bolt of your specific model is covered in the service manual. You will not get the car to where you want it without it.

nebulosity
07-09-13, 10:41 PM
HA! Should I be embarrassed then that I was reading such a terrible manual in bed and on the toilet? LOL Yes, it was crappy, but at least it was something. I've had to combine various resources to make up for not having a factory service manual. It looks like I can get one off Rock Auto. Is that the REAL factory service manual?

I have the emisisons chapter and the V8 engine chapter of the haynes manual practically memorized. LOL I need new reading material! Where did you get your service manual?

This one looks a little different, never seen a hardcover but it might be right

Actually, I really LOVE that hard copy one in the first link!! For $25, I went ahead and ordered it, so even if it's not right for some reason, not much lost. I've seen the one in the second link around, and somehow I just wasn't sure about it, so I never ordered it until now. If anyone has ordered that particular copy and loves it (and it's different than the hardcover copy I bought), please let me know. I have multiple oinline subscriptions and books, so I'll get a copy of every different item I can get my hands on.

The "hardcover" version was an attempt to have a updateable version of the shop manual, so as new service info became available, the techs could remove the old pages and replace them with updated pages, thus saving the cost of printing up a whole new manual just to change three pages. Silly pre-computer days! :lol:

07-10-13, 07:59 PM
I had one like that for my GN. I had to buy 3 gigantic 3-ring binders for it and the pages were stupid thin so they wore out in a hurry. Of the 3 million or so pages, only about 50 actually applied to the Turbo Regal. But it was fun thumbing through it. Someone took the time to put it all in PDF format back in the late 90s with a searchable index and table of contents. S/he must be a saint.

So today we reinstalled the steering pump pulley and the harmonic balancer (98% of the way). Without a crankshaft bolt and without any kit having the right adapter, we had to make our own installer tool from threaded rod, heavy nuts, washers, and the bearing from the harmonic balancer installer kit we bought that DIDN'T work (at least we got some kind of use out of it??).

Anyways, to get the last 6mm of the harmonic balancer pressed in, we're going to need a washer with a big center hole to allow the crankshaft to pass through as we snug it into place.

Welcome to the asylum. I for one am jealous of your wrenching ability--stay at it. These cars are uniquely rewarding to drive and own and have more personality in one fender than most anything else I have ever owned (which is why my 77 has seen a lot of cars come and go next to it in the garage).

Hey guys! Just wanted to give you a quick update to keep this thread alive. :D

1. Finished putting on the crankshaft pulley assembly,
2. Put a new thermostat in and bolted the top of the thermostat housing on with gasket and RTV ( Haynes manual said "gasket sealer" and so my best guess was RTV because it's the same kind of mating surface as the water pump.)
3. Reinstalled the AC pump (had to adjust my fabricated EGR tube because it was slightly in the way)
4. Installed new belts (except for one, which I'll have to order, so I just put the old one on).

Today I'm going to:

1. Tension all the belts and
2. Start putting the radiator on.

The project is moving forward!

I ordered the shop manual, and it's out for delivery, so it'll be here today! Wee! It turns out that the seller accidentally initially sent me a shop manual for an '85 Fleetwood DeVille FWD/'84 Cimarron, but he realized it quickly and also sent out the right shop manual. The '85 manual came yesterday in the mail, and I spent some time reading through it last night, and OMG I AM IN LOVE. I cannot WAIT to see the shop manual for my Caddy!!! I can't believe that there is THIS MUCH INFO for repairs on my Caddy all in one place! I'm so excited.

They are the best. I bought both computer and hard copy of both service and body manuals, even several other year's models.

I picked up the Chilton and Hayes books too, but just for the alternate drawings/photos. They are way to general to be anything but supplementary. (Although as great as you have done with one I may have to rethink my position on that!):hmm:

I had my FSM delivered at my office, which is full of car guys. Not "real" car guys (as far as I'm concerned) since they all drive late model audis and mercs and pay people to mod their cars, but when they saw that thing arrive at my desk they took one good look and promptly sh*t their pants.. I'd been waiting for it for a week saying "I can't wait for the bible to get here", and when they saw it in all its 1000+ page splendor a couple of them promptly bowed their heads and paid respect. Literally.. It was quite the comically whimsical sight that I wished I'd caught on video.

I still randomly read mine even when the car's running right. Sitting on the coffee table as we speak although it makes its way to the bathroom more than any other book these days. GM did a good job with this stuff.. And yes, on our cars the electrical section is worth its weight in gold. And then some...

I think I'm most fascinated by the emissions system because it's the most mysterious to me. I took an electronics class in college and learned how to debug circuits, so the theory generally makes sense to me. The Caddy will be a nightmare though because my dad put an alarm system on it in the 90's, and it's caused strange behaviors in the Caddy for as long as I can remember. I also have an aftermarket stereo, so who knows what kind of work they did there. I mean, they couldn't have made that much of a strange mess, right? o_O

I love, love, love this shop manual~!!

Ironically, I loaded the machine up this morning. The local supermarket was out of Mexicans so I had to get the smaller bottles (8 oz) US formula. At least in those I can get diet. I need to check out Sam's Club. I hear they have the Mexican Coke and Sprite.

Funny enough, I don't tolerate the aspartame in Diet coke either... it's actually worse than the high fructose corn syrup. o_O I just try to stick with real ingredients and just limit my intake of them. In all reality, I shouldn't even drink the mexican coke, but as long as I have a meal with it and drink a single bottle over a couple of hours, I'm usually okay.

Anyways, sorry to everyone for derailing the conversation to coke instead of Cadillac! LOL

Speaking of, I have some good news!!

California won't charge me for all the past years registration fees for my expired Arizona plates because it's out of state!! YAY!!! Omg I was so worried that they were going to want to charge me for 7 years of California registration because my Arizona plates are expired. o_O

Today I need to find out what kind of tool I need to tension the belts properly. Does anyone have any recommendations?

Two auto parts stores of mine said I don't really need a tool to measure the tension on the belts. o_O Since I've never done it before, I'm just really wishing I could measure it the first time so that I know about how tight to make it next time. *Sigh*

It's more of an art. If they squeal, make them tighter. But make sure your starting point has a little give.

77CDV
07-17-13, 04:32 PM
They should be tight enough not to squeal, but loose enough to have just a *bit* of deflection when you press on them between accessory pulleys. Your shop manual looks like a fun bit of light reading! :lol:

csbuckn
07-17-13, 04:35 PM
If you dont find a tool for the tension, see how tight they are on a couple other cars, they are all about the same. They should feel pretty firm. Some say new belts should be even tighter because they will stretch out during their first heat cycle. But, the belts are going to give you problems anyway because there are so many of them and they pull from different ways on the crank pulley.

7 years?! That would have stunk. So I guess you are at the Base of about $91 a year like I am then. :p One good thing is that as long as it is out of the system in this state then you get to start all over. Make sure you tell them you didn't pay anything for it. :p

California is funny that way. Here if it sits for years you don't need registration. That is why my Cadillac came w/o title. Owner had lost it. Parked car in 86 got Cal inop certificate for ten years. He owed 15 years back registration and couldn't get a replacement title without paying it!

As to Mexican Coke, I used to buy a lot of Mexican Coke....but it was the 80's, and that is another story.....

Regarding tension on belts, I believe your manual covers this. I know it does on mine. You can use a ruler. Check tension with your thumb, push in on the belt midway between pulleys and measure deflection with a ruler and compare readings with service manual

I got the belts all tensioned, just by feel. I had two people check them for me and they said it seems okay, and that I'll be adjusting them again later anyway because they're new.

And guess who started (FINALLY) putting the radiator back on??? MEEEEEE.

I still have to tighten the ring clamps and the nuts on all the hoses and pipes, and connect the lower radiator hose. It looks like I somehow misplaced a ring clamp or two. o_O I'll have to get some at the auto store next time I'm there.

And omg, I realized today that my collection of screws and nuts that are left to be bolted back into place have reduced themselves to one (magnetic) bowl. This is just TOO WIERD.... It's a sign I'm getting close to finishing putting everything back together, and it's a little surreal for me...

How long has the car been down?

For the repairs I'm doing? Or how long since I last drove it?

I stopped driving it in 2005.

I started doing the repairs last August. So I've been working on it (on and off) for a year. It's 30 miles away from my apartment at a friends house, and with other life complications, 60 hour work weeks, it's been slow going. :/

I've been looking at the engine of this car relatively bare for the last year, so to see it with the components on the front, with the belts and the radiator in, it's all so strange. I recognize this engine compartment better when lots of things removed from it, and seeing it with it's components is foreign. lol

I'd connect the lower radiator hose and pour coolant into the thermastat housing to fill the engine block. Keeping the engine block cool and gunk free is key to that engine.

If it hasn't run since 2005 I would also make sure it actually turns over before you put too much more work into it.

Not with the heatwave we've got right now where even the breeze at 60mph is hot and muggy. But it's frankly too hot to be spending a couple of hours under the car too, so it's on the "to do when the car comes off the road this winter" list. I'll make do with sticking to the seats for now.

I relieved what little "pressure" (read: refrigerant) was left in the system this morning. It had bled down to where the compressor wouldn't run anymore. I'll probably crawl under it later today once the sun swings away from the blacktop. A series of extensions with a universal does work, but it's such a pain in the butt. The universal flops around, extensions come apart. Oh what fun. I'm headed to the Jersey Shore this weekend and really want to take the limo, but it has to have a/c.

Well I have to at least get coolant in it, right? The car attempted to start just fine, but because the timing was all messed up before, it wouldn't actually start. Power to the car was great, and the starter motor seemed great. I had oiled the cylinders a little bit with Marvel mystery oil a while back. I can do that again too if necessary.

So I tightened down all the radiator connections and started to fill it with engine coolant. I'm going to need to get another gallon.

Strangely I feel like we got a lot of stuff done, but we really didn't. I wanted to hook everything up on the distributor, but when I checked the distributor hole before seating the distributor, there was a lot of black crap that looked like RTV laying at the bottom of the hole. I asked my husband to help me fish out the crap. It looks like someone RTV'd the distributor into the hole. o_O Is that a common practice?

I asked my husband to make me a board to sit across the top of the engine while I put the distributor and plug wires back on. Much easier to work on the top of the engine that way. Saves your back and shoulders.

Anyways, I'm super tired. Gonna get some sleep.

The presence of RTV does sound odd unless the distributor and and head are different materials and someone was trying to prevent galvanic action--but then I am not an engineer nor did I stay at a Holiday Inn last night (it was the Renaissance in Nashville which was nice but has not had any, much needed, positive impact on my cognitive abilities).

I think the intake manifold and shaft of the distributor base are both made of steel. What's even more weird is that I don't remember there being any washers when I pulled it out. Apparently there is supposed to be a thrust washer? o_O

If its a metal washer, you may want to find one. Without it, the dizzy gears may not line up with the cam gear that good. I dont know if its that important but worth looking into. Might be the cause of the chain messing up in the first place if the out-of-aligned gears cause a lot of drag. Might not be nothing but maybe something.

Got a little closer today. I am really super-duper tired, so we'll see how detailed this update ends up being. z___Z

I re-hooked up the throttle linkage. For some reason that funny little plastic piston thing is not sitting straight, and I can't figure out why. o_O
127850

As part of the throttle linkage, I reconnected this spring...
127858

When I took off the valve covers a while back, I (obviously) had to take off it's little metal tab (i.e. vaccuum pipe bracket) . I accidentally put the tab on the middle valve cover screw hole, instead of the one nearest the front and put it in its proper place. I really tortured myself over this one because the spring is stretched a lot to hook it to the tab when mounted with the front valve cover screw, but there really is no way else to put it. Ah well. Unless you guys see anything blatantly wrong in the above photo, I'm calling it good.

127866

For the record, I fracking hate these crow's foot wrenches. They're too thick and too wide on the sides -- COMPLETELY useless!! I **WILL** MAKE MY OWN crows feet when I finally get the money and space for a machine shop of my own. -_- .. probably with a bunch of other tools I've wanted to make during this whole <strike>ridiculous</strike> project.

127874

Put a new rotor in the distributor because the stupid dinky old one broke where the metal tab mounts. :annoyed:

By the end of the day, I wasn't really that much farther along. This slow-going progress thing is really getting old. I spent most of the day fishing out nuts and bolts I dropped on top of the engine in impossible to reach places.

clogged fuel filter?...spray some starter fluid and see if it starts up with that. being that no fuel in lines for so long may need a boost for fuel

I just replaced the fuel filter, and I sprayed some carburator cleaner in the throttle body yesterday to give it a boost, but it didn't seem to help. Today I'm going to make sure that the throttle body is getting fuel, probably by doing something silly and primitive like loosening the fuel lines while my husband cranks the engine over. After I had replaced the fuel pump a year ago, I forgot to tighten them down, and fuel came out generously, so I know that the fuel pump *should* work, and that if it's working, there will be fuel in the lines to the throttle body. The car is also on a *slight* incline, so we'll probably hook it up to the Xterra and pull it onto more level pavement in case the 2 gallons of fuel I added yesterday is sitting at the back of the fuel tank or something (but it shouldn't because the incline is honestly negligible).

If I verify that there is fuel at the throttle body and not coming out the injectors, I'll go through a debug process and see if I can figure out why no fuel is coming out the injectors. Like I said somewhere above, I recently rebuilt the throttle body and replaced the fuel pump and visually verified that the injectors and pump work. Actually, I have a video.. you can see it too:

http://www.youtube.com/watch?v=QzebUC49DIk#t=1m57s

After I make sure that I'm getting fuel properly and the injectors are spraying, I also need to make sure i'm getting spark. This is the time I really wish I had spark plug wires that would light up when electricity is passing through them... Now I'm trying to conjure up all sorts of crazy ideas about how to hook up an LED to the plug wires.... LOL I just hate hooking and unhooking the plug wires to check for spark on this particular engine. :/

Anyways, I'm going through and writing up a plan for today. i'll post an update later. :)

All you gotta do is listen for the pump when someone turns the key on, not cranking, just turning the key to the on position. The fuel pump should make some noise for a couple of seconds, you can cycle the key off and on to test.
Also you can rent some "Noid lights" to test if there is power at the injectors. This is such a simple set up, no way you won't figure it out.
Also no big deal testing for spark, just pull one plug wire and have someone crank it over, you don't have to check them all.

Keep up the good work!

Thanks for the suggestions! When I installed the fuel pump initially, I went back there to listen for it when my husband cranked the engine, and I couldn't hear it. I have problems hearing in general, so it could be just my hearing. Maybe I'll have a friend listen for the fuel pump.

Noid lights? I'll have to read up on those -- I haven't heard of them before. :)

You can get them at autozone or O'reillys pretty much any parts store, you give them a deposit and when you bring them back you get your money, so they are free to use.
You hook them up to the injector wires to test for voltage causing the injectors to shoot gas.

But still no fuel to the throttle body. Caddy has a new fuel filter, there is 6 gal of premium fuel in the tank, fuel pump relay is working, but fuel pump doesn't seem to be turning on (I've never been able to hear it, even when it's working, so maybe it's working and I just can't hear it). The fuel pump worked WELL when I last cranked the engine in August 2012, possibly as late as October 2012, but it has sat unused since. The fuel pump may have something wrong with it. We're going to check the fuel lines for fuel between the tank and fuel filter, and we may drop the tank. I already called two of my favorite auto stores to make sure they'll have a fuel pump in stock in case we decide to replace it.

To me atleast, I think I hear a couple fires like it's trying to start up. Let me know what you guys think.

The reason why it's probably not starting with the starter fluid is I'm not confident about the initial timing setup. When we reinstalled the harmonic balancer, the crankshaft was rotated slightly away from cylinder #1 TDC, perhaps as much as 1/8 of a turn. I looks like I'll have to pull the distributor, rotate the engine exactly to cyl1 TDC and put the distributor back in.

Somehow I feel satisfied even though I didn't get it started today. I'm going first think in the morning (ditching work a bit, lol) to try to get this work done on the Caddy.

The spray from the fuel injectors is weak, so I doubt you'll be able to see it in the video, but here is the video I took anyway. :P It was great to have fuel in the throttle body again. My only guess is that in cranking it last fall to check the valve train movement, I ran the pump dry, but at the same time I remember taking out the fuel pump relay ( so that I could watch the valve train without spraying fuel everywhere. LOL It's either that I ran it dry and burnt it out or sitting for 8months unused killed it (...really though?), OR perhaps it had a manufacturer defect, and lastly, I'm hoping electrical problems are not to blame for it burning out. When we pulled out the fuel pump, I checked my soldering job from the last time I adapted the wiring harness to the new wires, and everything was beautifully perfect and intact. Yay! So hopefully no worries about my workmanship.

No firing sounds in this particular video. We'll fix the timing for sure tomorrow.

One thing you could try is to hold the throttle wide open while cranking. Most cars have a feature that turns off the fuel injectors when you do it. Works good when you have a probability of a flooded engine. Looking at the video, I'd bet you might get more response if you did it.

Last night we corrected the timing...

1. Set the #1 cylinder to TDC first trying the finger method (but that was difficult), and then we used a screwdriver, and that finally worked well.

2. Took off the distributor cap and saw that the rotor was two positions off, so we pulled the distributor base out, put the rotor where it's supposed to be (#1), and put it back in.

The temperature dropped really quickly last night and fog rolled in, so we just put everything back together, and we're going to go back today to try to fire it up.

Beautiful sight. These old Cadillacs are majestic beasts in motion. Nothing stirs my heart like seeing a long dormant classic taking it's first step to the restoration they deserve.

I applaud you as a mechanic, and as a collector/enthusiast. Like all of us you will never see a financial gain from all the love you pour into your car, but will be rewarded every time you pull into a store or gas station (...more likely since it will be often!) with the comments and compliments of admirers.

I put fresh gas in it, said a little prayer, and started on my 2-hour journey home. There were times early on where I was sure it wasn't going to make it, but by the time I got to the end of my journey it was running like a new car.

An old mechanics trick for lifters and other things that need cleaned out in there.
Just before you change the fluids dump about a half a quart of trans fluid into the oil.

Yeah, it was the weirdest experience. I found the car on eBay but it had sold. Called the guy and he said the person that bought it didn't have the money so he was going to re-list it. He said if I brought him cash, I could have it. I grabbed the tags off of my old limo and headed for Connecticut (yes, it's illegal but they're both black Fleetwoods, who's to know?). I got out there and the thing was down a steep driveway parked in the front yard. The air shocks weren't working so the back was sitting on the ground. He had washed it, but that's about it. He just sat on the front porch while I looked at it. We negotiated a price, I paid him and called me insurance company to add it. I asked him if it would make the 2.5 hour trip back to NJ. He just looked at me and shrugged. Great. It was mostly highway and whatever was wrong with it wouldn't allow it to go above like 50. It had no power going up the hills and was billowing black smoke. The Service Engine Soon light was on. But, as the trip went on it cleaned itself up and the SES light eventually went out. I haven't had to do a thing to the engine since I bought it except change the oil.

I think yours will react similarly once you get it on the road.

Type F is Ford's transmission fluid. Trans fluid has detergents in it that supposedly clean the innards of the engine of deposits. The guy that built my GN engines had me put a quart of trans fluid in the new engines for the first 100 miles. Not sure why. It might free up that lifter, or it might free up on its own. They get stuck in the collapsed position sometimes when they sit. Eventually it might pop open at operating temps and after it's run for a while. Or it may always have a tap - if it runs okay who cares?

Yes, it cleans gunk out of the engine well enough. You have heard of detergent gasoline? Well this makes your oil detergent oil. :p
Seafoam is ok too. I have only used it in the gas tank though.
Royal Purple I use in my Brougham as well. Some say that it keeps the engine too clean inside and can make leaks worse but I have never had it make leaks worse for me. :hide: I wouldn't use the Type F with synthetic oil though.

HT4100 + Overheating = Trouble!

On the straight-a-ways the engine temp was hovering at about 94C and seemed fine. When we started to climb a couple hills, I got a bunch of backfiring, and a loss of power, at that point it was around 105C, and I was worried because that's above boiling temp of water (although it's only 50% water, 50% ethylene glycol). I had to drive about a minute to pull over in a safe spot (Hwy 17 is nasty and narrow), and when I turned off the engine, the temp was reading 114C. After turning the engine off, it was dieseling for about 1 or 2 seconds. :(

We dropped the car off at a good local shop. It'll be nice to have a fresh pair of eyes check the car over. And I get a small break. I love car work, but man I busted my butt for the last 30 days and I'm exhausted. It feels good to put the Caddy in someone else's hands for a day.

Oh, I'm sure my previous compression readings are irrelevant now, but compression was decent in all cylinders except #5, which was a bit low. Hopefully I stopped the car before any major damage was done. Regardless though, I'm sure some about of damage has been done because it's not good for cars to overheat even once. :(

That was my FIRST plan back in early 2012, but California makes it REALLY hard to do engine swaps, and I don't have the extra money to gamble on that kind of thing. :( I'm hoping someday I'll find out exactly what I would be allowed to put in it (besides a rebuilt ht4100), and finally do a swap on it. I heard wiring harness conversions are part of the trouble too.

Will do. It may not be the transmission's fault... it seems that the engine didn't have enough power, and as a result, it kept the transmission in a lower gear to get torque (staying down shifted). The reason I say this is because as soon as I let off the throttle, the engine would go to shift to a higher gear. The fastest I could go was 30-35mph, but it was really working hard to be there, and towards the end, I could only hold it at 20mph. :(

Btw, this was while climbing a hill.

UPDATE:

Okay, so....... the shop calls me:

Guy: "The Cadillac is done and ready for pickup."
Me: "What? It's done? You fixed it?" o____O
Guy: "Yep."
Me: "What was wrong?"

Guy said something about there being a leak around the heater hose/heater core, and that coolant was leaking into (somewhere?) and then getting onto the exhaust manifold, which is why it was giving off white smoke. There was a part where the heater hose connects to that was cracked? And they managed to trim off that part and put the hose back on? And that the only other option would be to replace the heater core, but they don't really think it's all that necessary especially considering that's expensive?

Basically it comes down to the fact that coolant wasn't circulating as it should, which was causing the overheating.

I really don't think I caught the explanation right because the heater hose is on the passenger side running from the radiator to the firewall, and the side of the engine that seemed to be emitting the white smoke was on the drivers side near the exhaust manifold.

I'll have to hear it again when I get to the shop.

In the mean time I'm going to read up on the heater core/heater hose part of the system and see if I can make sense of what I remember from the explanation.

They said my head gasket is fine. o_O That's good news.

This is all just a bit weird.

Also, what I need to do is make sure the caddy can climb the hills of HWY 17 so that I can get back to San Jose.... my husband says it SHOULD be able to do a solid 50mph on those hills if it's running properly.

Let me know if you have any particular thoughts about this.

never heard of a leaking heater core causing a car to backfire and/or this "Sadly blew the rockar arm cover gasket i just put in"

If the valve cover gasket really blew out because of pressure then you need to check your crankcase vent or pcv valve because it will blow other seals like the front and rear mains and that would be a pain. I'm not sure if Jay made it a sticky but I did a thread on how to replace the heater core, pretty straight forward. I'm noticing that these 4100s aren't as fragile as I've been hearing. Not sure if I've noticed a member here that's had a running 4100 say that it blew on them.

True. I have to remember that the blown gasket problem still hasn't been resolved.


It would also have to be a big leak to cause the car to overheat I'd think...even with a plugged up heater core the car usually runs fine.

Could the hills have compounded the problem? The engine sure had to stay revving high just to keep 20mph on those hills. It seems to me that there was so much back pressure on the engine that maybe that's what blew the valve cover gasket. Then the question becomes: why is so much back pressure accumulating? My PCV valve is new, and I checked the vacuum system (in a basic way), so I would expect everything is running normally there. o_O

Yeah, I also looked up the cost of a heater core, and it's only like $25/$35, so I'm not sure why Guy said it would be "expensive." How long did the replacement take? I still don't know enough about the system to even say I'd want to replace it.

after the wreck in my 86, the trans would act up when the engine warmed up and lost compression, but would act normally until the engine warmed up (so it would work fine for anywhere from 5-10 minutes then start acting up. check the trans fluid for color/ smell but the trans should be fine.
BTW, given you had overheating+ no power+ blown valve cover gasket....maybe blown HG too? seems something caused quite the pressure build up to blow the valve cover gasket/ lack of cooling. Hows the radiator?

Interesting to hear how the transmission could be related. I'll definitely double check the transmission fluid.

The guys at the shop said they ran a test to be sure I didn't have a blown head gasket (apparently it wasn't a compression test, but a test of the exhaust gases to make sure there wasn't any coolant/oil? Not entirely sure here).

It would be nice if the loss of power is actually the same thing that cause the blown valve cover gasket, because then it would be two birds with one stone. The only question is now, what caused such significant back pressure in the engine to blow the valve cover gasket? I'm not sure, but I'm starting to wonder if my installation job wasn't 100%. I torqued everything down to spec (35 ft-lbs), but there was one valve cover screw that I had trouble tightening. Regardless, there was clearly too much pressure in there, and I'm not sure why. PCV valve is new and the vacuum system is working (as far as I tested it).

cadillac_al
07-31-13, 07:11 PM
If we go back to basics and think of the engine as an air pump, either the PCV system isn't working or it can't keep up with the piston ring blow by. Maybe a clogged exhaust would contribute to even more blow by. A clogged exhaust will also kill your vacuum and power, and the low vacuum will make the trans not shift right. I don't know how complicated the PCV system is on that car being from Cali and all. If it's simply a PCV valve running straight to the intake then there isn't much to fail there. It should have another compression test but my gut tells me the exhaust may be clogged. I hope your shop can get it sorted out quickly.

I like the idea of clogged exhaust. Also, the last time you reported about the fuel system, you said the injectors weren't spraying as they should. I'd get the exhaust tested somehow and get a fuel pressure reading. I think Al may be on to something with the exhaust. So did the valve cover gasket actually move off the surface or did it just leak a lot? I'd also wonder what the computer is doing to the fuel trim when it thinks timing is at 30 but it's actually at 10. Almost tempted to put it back to 30. You got a lot of things going on here but it's probably not this complicated.

Eep... let's not think those thoughts. :suspense:

Funny thing was I didn't know it was doing it. I got to the mechanics and commented to my dad how it was weird that I was doing 10 under the speed limit (because the 307 couldn't go over 25 or 30 without giving it over 50% throttle once warmed up and I didn't want to push it and risk it blowing up) and pulling away from everyone. My dad (who was following me in the van) said "didn't you notice the smoke?" I asked "what smoke?" And he said "there was a thick smoke screen rolling out from under the bumper. It looked like the car was on fire and it kept getting worse. I think that engine finally died." (I didn't notice any smoke, but I was worried about it making it to the mechanics....and it barely made it. It was making quite a racket the last couple blocks and it reeked of oil heavily, but it drove onto the lot.)

Caddy update:

They noticed the distributor wasn't bolted down securely and the timing was changing causing the power loss. Now, I know that we couldn't figure out how the distributor is supposed to be bolted down, so I'm not in the least bit surprised they found that out (although I didn't think it was the primary cause for loss of power).

Does anyone know how the distributor is supposed to be fixed in place after you set the timing? It seemed like someone had RTVd the thing in before I took the distributor base out, and I didn't RTV it back in because I didn't think that was the official way to do it.

Ideas?

There is a threaded rod with a washer and a nut UNDER the distributor base, but it's unclear to use how it does anything to keep the distributor from rotating... as far as we can see, it only keeps the distributor in the hole. There's supposed to be a clamp? When I took the caddy originally to be checked out at a place in san jose called Robbie's auto, they returned the car to me without the distributor bolted into the hole... it was just sitting in there. :(

08-06-13, 09:21 PM
There should be a bolt, or perhaps a nut on a stud, and a clamp to hold that distributor in place. It's engineered in a way that no human could possibly see or touch it. The engineers still giggle themselves to sleep at night. When you have the right parts, you'll need a distributor wrench (a 90-degree wrench) to get on the bolt/nut and even then you can get like 1/100" of a turn at a time out of it. It would take hours to tighten properly. Or at least that's how I recall them. YMMV.

Because of work, I haven't been able to go get the Caddy yet, but we're definitely going down to get the caddy in the morning. I need to test drive it to make sure it'll be able to handle at least 40mph. Once we feel comfortable that the caddy is in decent shape to drive up the 17, we're going to take it to get smogged.

Caddy update:

Took the Caddy for a test drive and to the gas station for a little more gas (first gas station fillup in years!!). The Caddy drove quite nicely! A lot like I remember it. Not a race car obviously, but it absolutely did not struggle or backfire, even on modest hills. I got up to 45mph no problem whatsoever.

The only issue now is that it still needs a new valve cover gasket and one of the holes probably need to be re-tapped. Since I apparently screwed it up last time, Im just gonna let the guys at Larrys take care of it. They wot be able to get to it for a week or so, but theres no hurry since my moving permit is good for 60 days.

We're on our way to go replace the battery because it doesnt really hold a charge anymore. Then we go pick up the calve cover gasket at winchester auto, put in the new battery and leave the new gaskets in the Caddy.

It was throwing some codes at first: 12, 15, 23, 30, 52, but after we took out the battery (and then had to put it back in to move the car, lol) effectively clearing the codes, I was getting a 16 and a 52. I left my shop manual at home by accident, so I cant remember what all the codes are. Some are probably related to the fact that the auto shop guy played with the distributor, and I expect those codes wont stay long after we get the new battery in, Ill clear the codes, start it up and try again.

Sorry, no. That's really loud. Rockers just kind of "tick". Anyone that has been tortured by adjustable rockers will tell you that running the car with the cover off while you adjust them is messy but not loud. Something else wrong there.

Got a call from Larry's and they said the Cadillac is ready for pickup. I asked them if their tech found any broken rockers, and he said "none of the rockers are broken." I'm a bit skeptical because the last time I asked Guy something over the phone, I asked if the technician had test driven the car, and Guy said "Yes, the car drives fine." It turned out that the technician HADN'T test driven the car, and that the car was definitely NOT fine. As a result, I'm really skeptical about his response with the rocker arms. Anyways, I'll go pick up the Caddy later this week, let it warm up, and listen for the same loud sound I was hearing last time. If I still hear that sound, I'll have the mechanics listen to it again.

Yup. When I go pick it up, I have to make sure none of the codes are coming back and that it drives well. Then, if I'm lucky, I make the scary trek up highway 17 to San Jose to get it emissions tested. I have a feeling there may be one more thing that needs to be fixed before we take it up to San Jose.

Shocks don't keep the car level. They only keep it from bouncing too much over bumps.
You probably have worn out springs.

Does your car have ELC? (Electronic Level Control)

Yes, but when I replaced the shocks last time, I wasn't able to get the ELC compatible ones (they said they stopped making them?). I didn't have time to search around for the right shocks back then, and my friend said regular shocks would work fine, and he was right, they worked well. The tail of the car had stayed at the same level until just the last few weeks, so something has changed. How can I know whether I have bad springs?

77CDV
08-22-13, 10:25 PM
Springs don't usually collapse suddenly like that unless they physically break. If the shocks have gone bad, and they can go bad suddenly if they develop a leak or somesuch, the car will settle down, and the effect will be more pronounced if the fronts are still good. You had the engine out of the car for a while, fundementally changing the weight distribution and putting a sustained extra stress on the rear suspension. This may have compressed the rear springs or worn the shocks to the point of sudden failure.

Cherie, I just read all of your posts, and I am impressed by your determination! Doing the type of work you are doing without the benefit of a garage is tough. I really hope all goes well with your engine. I wonder, though, if you might want to have your car checked out at another place? First, a third set of eyes couldn't hurt. Secondly, especially in California, where older cars are much more common, maybe you could find someone who works more often on older cars? I don't get the impression that the head gasket issue has really been answered/resolved by the current shop. It sounds like they are not doing a good job of communicating what they have found. I know the 4100 is not a power house, but it should be able to go up a hill. Anyway, thanks for the great read, and I'm rooting for you and your old Caddy.

You need to know the length and thread pitch? Or just the bolt head size? And how can you fix the leak with that info? I would imagine that it would leak if your gasket didn't make a good seal at that location. Did you torque everything down properly? Was the gasket surface nice and smooth when you put it all back together, free of old gasket material and nicks in the surface?

If it is the same colors used in 1980, it is called Flax, color code 59. Does it show this code on the plate affixed on the cowl?

Where is the cowl? Is that the one inside the door?

As you know, the Caddy passed, but it actually BARELY passed. Concentrations of NO were borderline. REALLY borderline. I'm going to be doing a lot of research into how to improve my car's emissions before next year's test because the technician says that the limits are becoming stricter every year. If I want to keep driving this car, I'm going to need to stay on top of emissions as best I can.

I wouldn't start looking into the emission levels until you have driven the car a few hundred miles to wake it up.

So is the car driving with relatively no problems now? No more noise and decent power?

The cowl area is where the wipers are. The plate I mentioned is under the wiper arm on the driver side right below the windshield
