I had a earlier post asking how to free up a stuck 216 engine in a 1953 Chevy Truck and tried all the suggestions but the engine is still stuck. Has been sitting with rust buster on top of the pistons for a few months all but one of the pistons still has the rust buster sitting on top of the piston the rest of the pistons it has drained around the rings would be my guess. I was wondering if some heat with a propane torch around the outside of the top of the piston may help loosen up the rings being careful not over do it and melt the piston if it is aluminum. Tell what you think. Thanks!!!
