: Engine Cleaning, olds 307, Help Please.

06-09-10, 10:42 PM
I've been wanting to detail my engine for a while now but I've always wondered what exactly needs to be covered so it doesn't get wet, all I know to cover is the alternator, ac compressor connection [the one right on top of the compressor], blower motor, battery i guess and thats all I know for sure. I need to be able to pretty much just spray the hose with a pressure nozzle into the engine bay [not high pressure but enough to loosen up and spray away the dirt and grime once its broken down some with the engine degreaser and purple power cleaner/degreaser]. If I'm not able to spray in there pretty well there really wont be a point to cleaning it because it would just take days and days to clean it if I carefully carefully clean small areas at a time and rinse with a squirt bottle or something that aims a small amount of water. thanks guys sorry if this has already been answered

You've got the right idea. also get a soft bristle brush to get all the nasty spots. and when your done spray some tire shine on all the plastic pieces to get it a brilliant shine.

I just cover the Air cleaner housing (TAC) and the part where the hot air door spring mechanism is on the end of the TAC...that's pretty much about all for covering for me..however covering the alternator, A/C compressor, battery is great to cover as well, I should get used to doing that too.

..Then I spray some simple green everywhere (on a warm engine), let it sit for about a minute or two, then spray it down with a regular spray head, not a pressure washer.

Then I would spray the simple green again after the first rinse off (after it dries a bit) everywhere, especially on the rubber parts, and let it dry by itself without rinsing it off the second time.

I hear simple green also "conditions" things such as the rubber vacuum lines and rubber radiator hoses, so they don't crack as with some other harsher engine degreasers.

I also do this with a warm engine, it would make sense since its easier to remove the dirt/grime with a warmer surface than a cold one...IMO

yeah I saw yours man it looks WAY better than before, I have the 307 though so I needed to know if there was anything else besides the obvious that I needed to cover. plus on the 307 there's more lines cluttered around the valve covers so it'll be a bit more difficult to get all the nooks and cannys

Personally I've tried cleaning the engine and it is never worth it. Is there really a reason to spend two hours scraping the sludge off the intake manifold? You can't see the engine through the miles of hoses. When I do take the time to clean the engine, I spend an hour scrubbing every reachable surface with Armor All Cleaning Wipes or paper towels and degreaser, and then use the Protectant wipes to shine the hoses and plastic and hoses; the engine is the only place I use Armor All.

But to completly degrease the engine, you should remove the air cleaner assembly (that can be cleaned in your kitchen sink) and cover the carburetor along with every other electrical device under the hood, and the openings for the PCV system. You don't need to worry worry about the harness, but make sure that all of the connections are protected.

I finally bought a cheap pressure washer last year and I can't believe I didn't do it 20 years ago. I started using greased lightning too and I'm saving a mint $ by not buying aerosol engine cleaner anymore. Engine cleaning has never been so easy for me.

2 hours to clean your engine, way to long, get it clean 1 time then after that its easy to keep it clean, takes me about 10-15 minutes and my engine shines for months off one clean job. now i have a 95 fleet not a 307 older lac but all you need to do is cover the aircleaner intake to the carb. the alternator is not necessary at all. the thing that gives people problems is they use a pressure washer which will force grease out of bearings on the alternator and force water into electrical conections possibly shorting them out.

my method and i been doing this on lots of cars for lots of years

wet engine

spray degreaser all over engine ( Car Brite Hot Stuff)

use a carwash brush and soapy water to loosen any grime up

regular garden hose wish pressure nosel, hose all soap and degreaser off

i take an airhose to speed the drying process up, blow all water off

(Car Brite Special Protect All satin Dressing) spray the whole engine compartment, it goes on white and drys to a shine

this is my engine year round, 15 minute clean job

When you guys cover the different parts, what do you cover it with. I may try to clean mine this weekend. Wifey is out of town, so I get to spend a lot of time with my ride. Gonna give her some undivided TLC/

been wanting to clean mine too. I think i'd use a shopping bag or something to cover up.

06-11-10, 01:37 PM
yea just a plastic bag to cover the intake, keep water from getting in the carb and your good

06-11-10, 06:31 PM
This sounds funny, but I always use an old shower cap to cover the carb...

That's about all I cover, too. Of course I take care around connections & so forth. And that's on a 425 with fewer things to worry about.

06-11-10, 07:13 PM
That's actually not such a bad idea. I just always kept the TAC there and covered it with plastic food wrapper...but I was never able to clean underneath the TAC...

I think ill do what you do next time. Great idea

Did one round of cleaning on this 21 year old engine. Probably the first time ever. I'm gonna definitely do another round. I got questions about all the hoses I'll post on another thread.

06-14-10, 01:01 PM
looking good man! wanna do my 307 next? :D

06-14-10, 02:27 PM
Looks real good man!

That sounds very practical actually...save that I don't own any shower caps. In all sincerity my engine could use a good cleaning again, as though it ISN'T that bad, some parts could use some attention. It's fun to find scattered pieces of plants that are not native to this corner of the country. The interior could use a good cleaning actually, specifically the floor guards. Last time they got cleaned was when that putz at the drive-thru dropped my drink while trying to hand it to me.:mad:

Could have been worse though, I'd have killed him if he dropped my drink at the Drive Thru Liquor store...(Yes, we have those here. No, I don't actually shop there, the authorities already pick on me enough)

06-15-10, 03:00 PM
drive through liquor store?! NO WAY!!!

06-15-10, 06:27 PM
^We got them all over Ohio. Call 'em "Brew-thrus"


06-15-10, 11:16 PM
drive thru liquor store is unusual in USA?

here we call 'em "bottlo's"



sorry, I know I got OT....but booze is one of my other hobbies... ;)

I would definitely cover the alternator. When I degreased my engine (at a car wash), I didn't, and for three days the alternator wouldn't charge the battery and the Charge light came on. Seems nobody mentioned covering the distributor cap. That's always what I've been told to do. Anyway, your motor looks great., even under all those vacuum lines.
