I just changed the headgaskets and replaced all the coolant hoses on an EA81 engine that was sitting in a parts car.It seems that the piston rings are sticking because it sat for so long.Anybody know of a way to get the rings to unstick themselves.The engine only runs as long as I spray either down the carb...I dont want to tear the engine down..

If it's running then how did you come to the conclusion that the rings are sticking? If the rings were truely stuck the engine wouldn't turn over let alone run....

Do you mean they aren't sealing? Have you run a comp. check to verify this?

the motor does spin like it has no compression. Im thinking the rings are stuck to the pistons and not fully sealing against the walls. Valves mabye but when I turn the engine over by hand I dont hear any air escaping out the intake or exhaust manifold.
