Good Luck! A solution to your problem I've long wanted to try is; park the truck on a pretty good hill. Pull sparkplugs and pore several ozs of Coke in each cylinder. Then with the transmission in high gear walk away for a few days. When the truck is at the bottom of the hill you'll know the carbonic acid in the Coca-Cola has done it's job of dissolving the rust that had rust-welded the pistons to the cylinder walls.
