11617531423 PCV Membrane for BMW M54, M52TU
This PCV membrane is designed for BMW M54 and M52TU engines using OEM reference 11617531423. It replaces the worn rubber diaphragm inside the crankcase ventilation valve and helps restore correct CCV / PCV system operation.
The membrane is intended for targeted repair of the existing crankcase ventilation valve. It is not a complete crankcase ventilation valve, complete oil separator, or full breather assembly.

What This Part Does
The PCV membrane controls crankcase ventilation pressure and helps regulate the flow of blow-by gases through the engine breather system. When the original rubber diaphragm wears out, the valve can no longer maintain correct pressure and airflow.
Replacing the failed membrane helps restore the function of the crankcase ventilation valve while keeping the existing housing in service.
