PCV Crankcase Ventilation Diaphragm — Porsche Cayenne / Panamera 3.0T
Stop Oil Consumption and Crankcase Pressure Faults on Your Porsche 3.0T — Replace the PCV Diaphragm.
The crankcase ventilation diaphragm on Porsche 3.0T engines degrades over time — causing oil blow-by into the intake, increased oil consumption, blue smoke, and crankcase pressure fault codes. This is the direct OEM-spec replacement diaphragm.
Why Replace the PCV Diaphragm
- Stops Oil Consumption: A failed diaphragm allows crankcase pressure to force oil mist into the intake — this replacement restores proper regulation.
- Eliminates Blue Smoke: Oil mist entering combustion causes blue smoke at startup or under load — replaced diaphragm eliminates the source.
- Clears Fault Codes: Restores correct crankcase pressure and eliminates related ventilation codes.
- OEM Spec: Covers all production variants of the 3.0T separator.
