- oil separator diaphragm
- engine breather membrane
- CCV diaphragm
- BMW M52 PCV repair component
What This Part Does
The PCV membrane helps regulate crankcase pressure and controls the flow of blow-by gases through the crankcase ventilation system. When the original rubber membrane loses elasticity, becomes hard, cracks or breaks, the PCV valve can no longer maintain correct pressure and ventilation flow.
Replacing the failed membrane helps restore the function of the existing crankcase ventilation valve, supports stable engine operation and helps reduce oil consumption caused by PCV diaphragm failure.

This PCV membrane is listed for BMW M52 engine applications before 1998.
- BMW E36 with M52 engine before 1998
- BMW E39 with M52 engine before 1998
