Genuine Porsche Engine Crankcase Vent Valve Oil Separator

The Genuine Porsche Engine Crankcase Vent Valve Oil Separator, also called a crankcase breather valve, PCV valve or oil separator, is an original equipment part. It is part of the engine's crankcase ventilation system. It helps manage the blow-by gases that build up inside the crankcase during normal operation.

Key Features:

• Genuine Porsche original equipment part, built to factory specifications
• Separates oil vapor from crankcase gases before they are routed back to the intake
• Helps regulate crankcase pressure for consistent engine operation
• Supports emissions control by reducing the release of unburned hydrocarbons
• Helps limit oil carryover into the intake system

A worn or failing crankcase vent valve or oil separator can contribute to rough idle, oil leaks, excess oil consumption, or increased crankcase pressure. Replacing it with a Genuine Porsche part restores correct ventilation performance. Select the child item that matches your application to get the right part.
