You can pour marvel mystery oil into the cylinders and let them soak for about a week...This usually just works for engines that have been sitting for a long time...It,s worth the time to try...I had a land cruiser that had a seized motor due to lack of lubrication...I got stuck on a steep hill and ran the motor with no oil pressure...We just hooked up a tow strap and i poped the clucth at about 20 mph...She became unseized and I drove it for many years until I sold it...
