I checked the oil level, it's full. Only thing I can try is switching back to my usual K&N HP2002 oil filter (the dealer used the acdelco PF454 last time it was in the shop getting some oil leaks fixed).
If changing the filter does not help I'm afraid I'm gonna have to let the shop take the engine apart.....hoping it's something minor, a lifter or rocker being the worst they find.
