stuck motor

[fordrelic]

Hey, Maybe someone has some good suggestions with my issue.
I purchased a Model A from an estate and the former owner started restoring.
The motor has been completely rebuilt as rumor has it. It was rebuilt maybe 15 years ago and has never been started. I don't believe they ever put oil in crankcase. (need dipstick) The motor will not turn with hand crank. What suggestions do you have. It is bolted in chassis with body. It has been in unheated garage. It seems they got motor done and bolted it in chassis but never got back to finish up, not even a oil cap. Motor and trans bolted in and that's it.

Thanks for your help.

No trans, or rear end? Will not roll??

Mix up 50/50 acetone and MMO. About an ounce in each cylinder and let it set a few days. In the meantime buy a dipstick, filler cap, and oil. Give it time.

Thats quite awhile for an open engine to sit without being pickled. I think I'd pour some ATF in each cylinder and let it sit for a week before trying to nudge the engine with the crank.

Is the starter in it ?? If so Make sure the bendix is not stuck in the flywheel or the starter bolts could be to long...
just throwing something easy out in the mix

Below is some information I got many years ago when I was trying to get a 49 Dodge truck started so all may not apply to model A but there is some interesting ideas mixed in there.
"Don't go out
and start cranking on your breaker bar hoping to force the thing.
Pull the plugs and pour whatever your favorite elixer of lubrication
is in each cylinder. And dont be stingy. Pour ALOT of fuel oil,WD-
40,Gibbs oil,Kroil,Engine oil,kerosene,Marvel Mystery Oil,Sea
Foam,ATF,or what-have-you. At the least,let it sit a few days. A
month wouldn't be overdoing it,but should be plenty. When you come
back,re-pour some more lubricant. There are 2 places you can
find "purchase" to turn your motor over. (By the way, there
shouldn't be spark plugs in it.) The front of the crankshaft,and the
rear of the crankshaft(or flywheel). In both cases you'll need
leverage. LOTS of it! No 2 foot,half inch breaker bar here. First
off,you need to make sure the engine is SECURE. Tie it down,chain
it,strap it to a post,or whatever you have to do to keep it from
moving around when you're "reefing" on it. If you have a large bolt
in the center of your crankshaft use a six point hardened impact
socket,and preferably a 3/4 drive breaker bar. Attach to the end of
that a length of pipe for leverage so yo don't have to leave a
couple of round pink things on the ground when you're
pulling/pushing on it. Give that a try. If you don't have a big bolt
on the end of the crank, go to the hardware store and buy some grade
8 bolts 4 or 5 inches long that will thread into your flywheel
damper bolt holes;or you're clutch mounting holes on the flywheel.
(Or BOTH if you have an assistant) Thread long bar or length of pipe
through and lever on those(keeping the lever device close to where
the are threaded in so as not to bend or snap off the grade 8 bolts.
If that doesn't work and you have a seriously stuck engine you can
get an old spark plug , break the insulator out ,weld the hole
closed ,drill it through and tap it or weld in a "zirk" fitting.
Find out which cylinders have the valves closed. screw in the
converted spark plug and start pumping in grease untill the cylinder
is full. Then keep pumping in grease. This will yield hundreds of
pounds of evenly distributed hydraulic pressure to free up
that "stubborn" engine. Don't forget that before you start all this
heavy duty levering and such you should be sure that a mechanical
failure such as a broken connecting rod isn't responsible for the
engine being stuck in the first place. If you're not sure pull the
oil pan off and have a look. These techniques should get "most"
engines unstuck. Good luck,and "safety first" in these endeavors. "

Check that the beveled teeth on the ring gear are on the back side. Learned the hard way - not from an armchair.

I rebuilt an engine that had bad mains. I had new mains poured (not rods) and that crank was so tight, you couldn't move it by hand. It could be moved with a long wrench on the flywheel, and the starter. Certainly the engine needs some lubrication, but if each cylinder is full or even half full of a liquid then you get hydro lock when that cylinder is on compression. Go lightly with pouring large quantities of anything into it.
Model A s excel at locking the valves up through sitting too long. with the valve cover and the manifolds off, make sure lots of Kroil, WD40, 50/50 acetone/ATF, MMO gets on the valve stems.
One last note. Machined surfaces always rust if not covered in grease, oil, Cosmoline, etc and this rust scrapes off as a fine 'grinding" compound. Cams, cylinder walls, valve stems, etc are all probably have some fine surface rust that will rub off. So whatever oil you're going to use, be prepared to dump it after twenty minutes running. I use the cheapest junk oil I can find on sale.

Do you have access to a borescope, you could look at the cylinder walls and see if the cylinders got rusted up at all before you start fighting/turning it

I was recently given an engine that has been patiently waiting for 40 years in a club members garage. This was a "spare" that came with his car. But it never happened, he never needed to change engines. True story.

Anyway it was stuck. Poured 50/50 acetone/ATF in the cylinders. Pulled the valve cover and sprays the acetone/ATF on the valve stems. Also squirted straight 20/50 to the mains.

And waited. check once in a while. After ~1 week I could see the oil was getting a pink tinge to it from the ATF so I knew it was "penetrating".

It is now free and I have the head off and it looks "pretty good" inside, so far. Looks like it was run but not very long. I guess I was lucky it was "put away" before ethanol.

Moral of the story, Be Patient.

lots of good ideas. Thanks and more ideas welcome. I will pull plugs and get something working. Also fill crankcase. With a little labor I could try to pull car and pop clutch. Would this be a bad idea after letting it soak?

[Art Newland]

Any chance that since the engine was rebuilt that it's just too tight to turn with the hand crank?

That's a good way to bend connecting rods or break something. Let it soak and at the most try prying on the flywheel teeth while using good judgment.

I knew a guy that would restore antique tractors. He would buy them with stuck engines and would get them onto his flat bed trailer. He would remove the sparkplugs and put in MMO in all of the cylinders.

His trick was to then put the tractor in any gear and he have the fastening chains loose on the trailer so it allowed slack enough to rock the tractor. Typically on the drive to get the tractor home with all of the stops and starts it would start rocking back and forth enough to loosen up the engine. Easy Peezie..

No, I don't think so. As long as you know when to stop. Pull it forward in third gear ( 1 to 1 ratio) Before you go to that trouble, try putting it into gear (3rd) and rocking it with the rear wheels and see if that doesn't free it up.

See my album," My 38 Allis Chalmers". When I got that machine, it was stuck. I poured MMO into the cylinders, waited a few days and soon it was free. I started it on the old oil and drained it out as soon as it was warm. It ran great!

This would be the first thing I'd consider. Then, if you have determined the starter is not jammed, pull the head and inspect the cylinders. Proceed slowly, one check at a time, simple stuff first, dont force anything.

Forgot pictures in my other post.

Thanks. I probably should have been able to figure that out. Real tough to get to the cylinders from the valve chamber
