i have oil coming up my dipstick tube under boost? motor has been recently rebuilt. thought i was crank case pressure but i put a air filter on the valve cover and makes no difference. anybody got any suggestions?
blown head gassket , i would think on the intake side . sorry for my thoughts on this one .....
Check the rubber base that holds the valve cover filter in place. Make sure you cut the part open that goes inside valve cover so air can transfer, and is not chocked off. had same problem after new rebuild and the pushing out of oil went away :smile:
One thing is for sure: You have excessive crank case pressure.
If the car does not smoke (on a new motor), my guess is a leaking HG or intake gasket.

I would start with a compression and leak-down test.
