I guarantee the pistons in there are no good. I would cover the crank with a piece of tin, then use a cutting torch (not the oxygen jet, just the preheat flame) to melt one side of the piston top (90 degrees fron the pin) about 5/8" from the wall. Melt in 5 minute stages, first a hole, then the edge of the hole toward the wall, then the edge of that. As soon as a glob melts out, I would stop for Five min. then do it again. When the rings are seen from the back side, I would touch the oxy lever just a burst to blow them out the bottom 1/2 second at most. once this has been taken to the bottom ov the compression rings, the piston should be easy to pop loose.
