What This Part Does
The crankcase ventilation diaphragm regulates pressure inside the engine crankcase and controls the flow of blow-by gases and oil vapor through the PCV system. In BMW / MINI N13, N16 and N18 applications, this diaphragm is built into the valve cover and can become rough, cracked or broken over time.
When the diaphragm fails, the engine may develop unstable ignition, idle interruptions, increased oil and fuel consumption, starting problems, or a whistling noise near the valve cover. Replacing the failed diaphragm helps restore proper crankcase ventilation while keeping the existing valve cover in service.
