    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

    This is why I don't like other mechanics working on my car... I've found parts missing more than once..

    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.

    Re: Cherie's '84 Coupe DeVille Project

    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
    gsmIMG_3338_throttle_linkage.jpg

    As part of the throttle linkage, I reconnected this spring...
    gsmIMG_3340_throttle_linkage--spring.jpg

    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.

    gsmIMG_3341_tab_location.jpg

    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.

    gsmIMG_3335_crows_feet.jpg

    Put a new rotor in the distributor because the stupid dinky old one broke where the metal tab mounts.
    gsmIMG_3334_new_rotor.jpg

    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.

    Re: Cherie's '84 Coupe DeVille Project

    I also spent some time looking at what I could gain from taking the front of the car off for putting the Caddy in the garage (related:http://www.cadillacforums.com/forums...r-removal.html ), and what kinds of things need to be unfastened to do so. Yes, that's right ppl. I think I'm just going to take off the front grill and surrounding parts up to the radiator.

    Bumper removal experiment will happen AFTER I get the Caddy started and BEFORE it makes its 25 mile journey to my apartment in San Jose.

    Jayoldschool basically gave me permission to spam you guys with a million photos, so blame him for the spammage. ;D

    Re: Cherie's '84 Coupe DeVille Project

    Today:

    1. Checked the vacuum lines and electrical connectors to make sure everything is hooked up.

    2. Changed the oil

    3. Tried to siphon old fuel (there was none left), and added 2 gallons of new fuel.
    gsmIMG_3370.jpg

    4. Checked for leaks. (There was one at the thermostat, but my husband tightened down the hose for me and it stopped leaking).

    If you wanna hear me be ridiculous and yack about the leak...



    5. Topped off the engine coolant.

    6. Hooked up distributor and plug wires. The "me" of 6 months ago was smart enough to put numbers on the wires near the boots on the distributor end -- WIN!

    gsmIMG_3372.jpg

    gsmIMG_3377.jpg

    7. Hooked up the battery.

    8. Tried to start the engine. No fuel coming out of fuel injectors. Will try a few things tomorrow and go through the usual "does it have fuel?" "does it have spark?" etc debug path and see if we can sort out any issues.



    I'm sore and tired. Whine, whine, whine. lol. That's all I have energy to write tonight.

    Listen for the fuel pump to come on, press the fuel schrader valve and see if any fuel comes out, get fancy with a DVOM and see if the injectors are getting a signal, the alarm might be cutting fuel, fuses not all good. Just random thoughts for your next trip.

    Re: Cherie's '84 Coupe DeVille Project

    Part of me is terrified I won't be able to get my Caddy running. I mean, this isn't rocket science, but sometimes I start to get paranoid and feel like it is. Every once in a while I have moments like this.

    I go to work on the caddy after I get off work in a few hours. Let's see what I can do.

    Re: Cherie's '84 Coupe DeVille Project

    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.

    Re: Cherie's '84 Coupe DeVille Project

    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!
