There's no way I can get anything in there to bang them out from the bottom with the crankshaft in the way. I'll keep soaking them with penetrant for a while and see what comes of it. One side is worse than the other on top of the piston, and underneath the pistons the bore feels pretty smooth yet, and not rusted. I wish the crank pin was positioned to the right or left, then I think banging the pistons from the top would knock them loose a little easier. Right now with it stuck at the top position, banging on the pistons is basically forcing the piston and rod directly into the crank pin and stopping any motion right there.
