Default Re: Stuck Piston Rings

I would remove the spark plugs and fill all the cylinders with MMO.
Let sit over night and just jog the engine a little and refill and let
it sit another day or two. Fill again, put plugs in and spin with 12
volts to the starter. This should force the MMO into the ring grooves.
Take your time and don't rush. G.M.
