Thanks for the reply. I just remove my air filter and I found oil on the filter and in the box. I am not sure if that is normal.You could install a catch can and stop it from getting that far. It's being forced out the valve cover when you are in boost. Make sure your PCV valve is working as it should. Should close when you blow through it backwards towards the motor.
If the oil is getting that far it's coating the turbo blades and then gets into the IC. Hard to clean it out.
