11127646553 Valve Cover Diaphragm for BMW / MINI N13, N16, N18
This valve cover diaphragm is designed for BMW / MINI N13, N16 and N18 engine applications using OEM reference 11127646553. It replaces the failed PCV membrane in the valve cover crankcase ventilation system and helps restore correct pressure regulation.
The diaphragm is intended for targeted repair of the existing valve cover PCV area. It is not a complete valve cover assembly, complete crankcase ventilation valve, or full oil separator unit.

What This Part Does
The valve cover diaphragm regulates crankcase pressure and controls the flow of blow-by gases and oil vapor through the PCV system. When the original membrane becomes worn, hardened or torn, the ventilation system may lose proper pressure control.
Replacing the failed diaphragm helps restore crankcase ventilation function, reduce oil vapor issues and support stable engine operation on compatible N13, N16 and N18 applications.
