i would say that if you can change those valve seals by putting air on each cylinder with the valve up, that would solve your problem. "time" is what gets those seals and one or two may even be so loose or even cracked from time that is letting oil run down the stems on top of your valves when its setting causing the smoke show. sounds like the rings and valves are in good shape just from your compression check and i think if it was a intake pan leaking it would never stop smokin.. just a thought
