OEM 948-107-245-02 Engine Crankcase Breather Hose Vent Line Left to Right Valve Cover

The OEM 948-107-245-02 is an engine crankcase breather hose designed for Porsche Cayenne vehicles. This vent line connects the left valve cover to the right valve cover as a critical component of the vehicle's Positive Crankcase Ventilation (PCV) system.

Key Features:

• Part of the PCV system that controls crankcase pressure ventilation
• Routes blow-by gases back into the intake air stream to reduce hydrocarbon emissions
• Precision-engineered for exact fit and compatibility with Porsche Cayenne models
• Replaces worn or damaged original breather hoses that can cause vacuum leaks
• Helps prevent check engine lights caused by PCV system failures

Damaged crankcase breather hoses are a common source of engine vacuum leaks in modern vehicles. This OEM replacement ensures proper crankcase ventilation and maintains optimal engine performance by allowing pressure to escape from the crankcase in a controlled manner while recycling combustion gases.
