What This Part Does
The PCV membrane regulates crankcase pressure and controls blow-by gas flow through the valve cover ventilation system. On BMW M67N diesel engines, a failed diaphragm can cause pressure imbalance, oil vapor issues and unstable ventilation function.
Replacing the failed membrane helps restore crankcase ventilation and pressure regulation while keeping the existing valve cover in service.
