Good question, Howard. Here are a few thoughts from a previous answer to another question about stuck piston rings. Be sure to check out the link below for more…
“There are a couple ways Sea Foam products could help with stuck rings.
First, you can add High Mileage Motor Treatment (1 oz per quart of oil) to the oil crankcase. To clean from the topside, I would remove the plugs, spray a healthy burst of Sea Foam Spray into each cylinder cavity. With Sea Foam Spray soaking on the tops of the pistons, let the engine sit with the plugs out for 3 days. Each day add another burst of spray to each cylinder and crank the engine for a few seconds to move things around. After 3 days, put the plugs back in and start it up. Repeat the whole process on occasion to help clean more of the ring buildup as you go.”
