Happy new year all, now back to the truck.
I thought things were good, but then it started spewing oil and I have traced it to the driver's side head. The circular cap on the back of the driver's side head (in line with the camshaft) is gone. Could it have been blown out by excessive pressure? Could this be due to a plugged PCV valve? Is there a diagnostic for this or should I just swap it out?
