Default Re: Stuck Piston Rings

quick might not be the solution. Try a few mmo smoke outs and run it hard for a bit, works well on valves too. Then look at leak down test. As mentioned not sure if this is a quick flip/sale.

On a hit/miss engine you can remove the piston and knock it on some wood to free up the rings. But that's a one lung and low compression.
