If it doesn't clear up after a short run time you may need to replace these. It can be done with the head on the engine, but it can be a PITA.
When I've had this problem in the past (SBC) but they only smoked on start up. The seals let oil in when I let the engine sit overnight. Once the small amount of oil burned off at start up it was good. | | |
