its frozen......

i have a chevy 350 that sat for a while. i tried to turn it with a socket and couldnt. i pulled the heads and there was some rust on the pistons but nothing major. i put oil in the cylinders, and let them set. oil was gone when i checked so it seeped in, but the engine still won't turn...

 

 

any ideas? :cry:

Three words... MARVEL MYSTERY OIL!!!

 

Squirt in each spark plug hole and give it some time....

 

:D :D

seafoam will work well too

Have you tried hitting the cylinders? Use a plastic or rubber mallet and a small block of wood to give each a whack to free it up.

Since you have the heads off, you can squirt the Marvel Mystery Oil around the pistons then do as Pete said as well. ;)

 

I know Seafoam is good for cleaing, but I am not sure how good it is at lubricating/penetrating.

Another vote for Pete's idea. I've done it in the past. It only failed once.

I prefer it as a penetrating oil over most anything, better than PB Blaster even. You can get it in a spray foam type called Deep Creep. Use it, let it soak for a few hours then come back with the hammer. I use the day before I work on the Jeep and let it soak overnight.

 

If none of this works, best bet, would be to go ahead and grab a new set of main and rod bearings and some rings, as well as a bottle brush. Do a mini rebuild.
