I take mine apart from time to time and wipe the oil out ,The PVC valves are ducted right into the intake itís what to expect , it was the only place they can put them to pass emissions, BMW donít care if the whole intake system is full of oil , if it gets bad , it will coat the turbo housings and intercoolers with oil , Oil catch cans can remedy this
