It is usually a little more smokey at startup, but even when the engine is warm,... it misfires and throbs quite a bit when coming to a stop and pukes oil out at all times. Especially bad after takeoff.
All engine speeds above 2K rpm's, now, produce a sizeable amount of oil smoke. In other words, all speeds < 50 mph.
Thanks for your help. I appreciate it.
I am hoping it is valve seals. However the culprit is definitely cylinder #1 only.
