50/50 mix of acetone and ATF from the topside, let it pool about an inch
deep and sit overnight.
Next day, it's 2x4 cut to fit bore size and big a$$ rubber hammer time.
If that doesn't work, you can try heating the cylinder walls with a propane
torch ( while trying to keep the piston cool ) thus allowing the walls to
expand a tiny bit while piston remains the same size and bang on it some
more.
Good Luck
