ESEN SKV Crankcase Breather Membrane – 31SKV260

Description

ESEN SKV 31SKV260 is an OE-quality crankcase breather membrane repair kit for BMW N57 diesel engines.

Mounted inside the rocker cover / crankcase breather system, this membrane regulates crankcase pressure and separates oil vapours before gases are recirculated into the intake.

A failed membrane can cause:
✔️ Excessive crankcase pressure
✔️ Oil leaks
✔️ Whistling noise
✔️ Increased oil consumption
✔️ Turbo intake oil contamination

Ideal repair solution when replacing only the failed breather membrane instead of the complete rocker cover.
