    My father showed me a truck to free stick cylinders with less brute force that can break the piston rings.

    Break all the porcelain out of a spark plug. Tap and thread the remaining metal bit and put a grease zerk fitting in it. Install in the engine and he used a brand new lever style grease gun. Start pumping grease to it. At 3000 psi and being grease it will pop right loose.
