What This Product Does

The valve regulates the passage of crankcase gases through the breather system. Correct operation helps maintain the intended pressure balance between the crankcase and intake, rather than allowing pressure or vacuum to become excessive.

Functions

• Controls gas flow through the crankcase breather circuit.
• Helps regulate pressure within the crankcase.
• Supports the ventilation system’s connection to the engine intake.

Symptoms of Fault

Breather-system faults can be associated with the following signs. These symptoms are not conclusive evidence that this valve requires replacement.

• Uneven idling or fluctuating engine speed.
• Whistling near the crankcase ventilation components.
• Higher oil consumption or visible exhaust smoke.
• Oil deposits around intake connections.
• Unusually strong vacuum when removing the oil filler cap.
• Leaks or damaged hoses within the ventilation circuit.
  
  

Why Replacement Matters

A defective valve can interfere with normal crankcase breathing. Renewing a confirmed faulty component addresses that fault, but adjacent hoses, connections and seals should also be inspected. OE Match’s Porsche-focused replacement programme uses application information and original references when assessing suitable components.

FAQs

Does exhaust smoke confirm a valve fault?
No. Excess oil, other ventilation faults and internal engine wear can produce similar signs. Establish the cause before replacing components.

What else should be inspected?
Check breather hoses for splits or obstructions, examine their connections and verify that the engine oil has not been overfilled.

Is an engine rebuild necessarily required?
No. A ventilation fault may be repairable without internal engine work. Further testing should guide any decision to dismantle the engine.
