I have an old engine block which I purchased, but the pistons are bonded to the engine block. The block looks like it is in good condition, but I have been unable to remove the pistons. I have tried dry ice and a hammer, a hammer and a chissel, lye (it did melt a hole in one of the pistons), and the good old cure coke-a-cola. So far no luck, any suggestions would be appreciated.
