Audi Engine Crankcase Breather Hose Check Valve Replacement

Audi Engine Crankcase Breather Hose Check Valve

The engine crankcase breather hose check valve is a small yet vital component in your Audi’s PCV system. It prevents reverse airflow, ensuring that crankcase gases are properly routed for combustion or ventilation. A failed valve can cause pressure build-up, oil leaks and rough idle.

Maintains proper airflow direction and crankcase pressure.

• Prevents Oil Blow-By: Stops pressure from forcing oil past gaskets and seals.
• Improves Engine Efficiency: Supports balanced vacuum and smoother performance.
• Reduces Emissions: Ensures vapors are correctly routed into the intake.
• Protects PCV System Components: Reduces stress on hoses and diaphragm valves.
