Perform a cylinder leakage test. That involves pumping in compressed air at 30 psi with that piston at top dead center on the compression stroke. Listen at four places to identify the cause of the leakage / low compression. Tail pipe: burned exhaust valve. Throttle body: burned intake valve. Bubbles in radiator: leaking head gasket. Oil cap or dipstick tube: worn piston rings.
