    Old rusty engine with stuck pistons. Suggestions please!

    Ok so I have the original motor from my stealth but it had been sitting outside for about 5 years. So I recently decided to tear into it so I could break it down for easier storage. Well ive got the block completely apart except the pistons and rods are stuck in the block. Does anyone have any suggestions as how to make it easier to remove them? I should really take pictures for you guys...this thing is pretty rusty.

    all i can suggest is soak the bores in WD40 or a spray lube like that, hopefully penetrates (giggity) and lets you slide em out...

    If the cylinders are bad...you could probably use some sort of round grinder the get the rust out and make it easier.

    ^agreed with the diesel idea. Let them soak and them smack each piston with a rubber mallet. That will help loosen things.

    Check it out on Youtube!!
