Trying to free a stuck engine...
Posted by: 1963RedBrier ()

Engine was stored in a dry (fine dust) barn for decades(?) without a bell-housing. I removed all the shrouds, soaked with engine degreaser and power-washed it (all holes plugged). Removed oil pan and it was pretty clean inside. Will install a bell-housing and clean oil pan with new gaskets. What should I pour inside to help free it up?

I've heard ATF?

Just ATF?

What about Marvel Mystery Oil?

How much should I put in each cylinder?

Should I put something different in the cylinders? PB Blaster? WD-40? Kroil?

Thanks! Greg

If it is stuck that bad, you probably need to take cylinders off and change out the rusted ones and maybe the pistons.

Been there, done that on 8 stuck engines. 1/3 of the cylinders were scrapped due to pitting. I scrapped the rest since there is no value in them. I still one more to go which had rusty water in one cylinder.

Get a borescope and look inside to see what is rusty and what isn't first. Then concentrate on removing rusty cylinders.

Endoscopes for cell phones are dirt cheap now. Do what Al said and peak inside to see what you up against. Also easy to pull valve covers and rockers to see if the valves are stuck

I've freed up a lot of stuck engines with penetrating oil. My new favorite is a 50/50 mix of ATF and acetone. I remove the spark plugs and fill the combustion chambers. With a Corvair cylinder sitting sideways it's best to remove the valve covers and loosen up the rocker arms so the valves are all closed. It takes some time, a few days or a few weeks or a few months. If it comes loose with a wrench be gentle, there's often a rusty ridge in the cylinder you need to massage past without breaking or damaging a piston ring. It may or may not work. Patient and gentle are key words. You don't want to "break it free" but "ease it into operation". I've never had a camera snake, I'm usually a decade behind the times at least.

Well, you know you need to put new o-rings on, those have to be neoprene, so with the cost of 6 head gaskets, go ahead and pop the heads off and work from the inside.thumbs up

I also like 50/50 ATF and acetone to free things.

I was able to get an EM 145 engine turning and running by putting ATF in the cylinders.
It was still in the car which had sit outside for years.
After adding the ATF to the top of the plug holes, I let it sit for a couple weeks, then would heat the cylinders with a couple heat guns blowing on both banks.
I had the top cover off and also added ATF to the crankcase making sure to get it right on the bearings.
I tapped on exposed crank throws with a hardwood dowel & hammer and was able to see that the ATF was being moved at the spark plug hole as I did so.
Next day I heated the cylinders again using two heat guns and then - hit the starter!
ATF flew 6 feet out of the plug holes!
I kept cranking the engine for about 15 min.
I then changed the oil, reassembled the top end, adjusted the valves and put on the carburetors. Started up and smoked like crazy for a while, then settled in to a quiet smooth and clean idle.
A great conclusion to the experiment!

If you just want to try to free up the engine do the following:
1- about 150ml of WD40 in each cylinder, let it seat over night.
2- next day about 100ml ATF in each cylinder wait 10min
3- Try it!

I'd be interested in what 10 minutes of ATF does when added to the WD-40. Is there a chemical reaction foaming or...?

I meant right after adding AFT you can try to see if the engine is free up smiling smiley


You can wait more but there is no pint since you already wait over night(24hr) for WD40.

Okay, so now I am confused.
If we are relying on the WD-40 to do the work, then why even bother with the ATF?
WD-40 was never intended for freeing up rusted parts.
WD-40, stands for Water Displacement formula #40.
It took them 40 tries to get the desired characteristics they were looking for.

1. using AFT just for more lubrication when you want to turn the engine.
2. WD40 will help removing and braking the rust:
[www.wd40specialist.com]
3. Can you tell me for what propose do you usually use WD40 if not for rust?
4. Anyway, what I suggested is quick and no harm you can try and see the result in 24hrs. if the engine still in stuck can go with other suggestions which take more than 2 weeks and lot of work.

Mojan...being from San Diego.... GG WATER DISPERSANT formula # 40 original purpose was to remove moisture in small areas.... We first used it to dry out Distributor caps after washing an engine at a car wash.

The WD-40 brand has many different products besides the "mechanics cologne" (original WD40) that many associate with that product name.
Mojan is using "specialist" rust disolver - seems to be similar to EvapoRust.

Look on the shelf with all the various lubes, spray oils, etc at a well supplied FLAPS and you'll find many different products under their WD-40 logo.

When I put a 50/50 mix of acetone and ATF in a cylinder for 5 days I wonder how much acetone is left. I wonder if a lot of it evaporates away leaving mainly ATF.

If the valves are closed and the plug is back in I wouldn't think much would escape.

Okay, now I see. thumbs up
We don't have that Fancy Stuff here.
Our local hardware store has original WD-40, and Marvel Mystery Oil.
Not much selection to choose from. sad smiley

This is going to sound nuts but I have a cousin who swears that Coca Cola poured into the cylinders will free a stuck cylinder. Says he has tried it on old tractor engines and had excellent results...

It can help to free up rust but it’s sticky I don’t like it...WD40 has more power.

Ratt 43,

I've heard that one too. Remember a science experiment we did in junior high. Placed a piece of aluminum foil in a Pyrex dish, poured Coke on it (this was on a Friday afternoon). Monday afternoon, when we went to science class, we were very surprised. Over the weekend, the Coke dissolved the aluminum foil! No wonder the stuff rots out teeth! Might want be careful using it in the cylinder, might dissolve your pistons! ggg
