Non-Return Valve – Crankcase Oil Breather
The crankcase oil breather non-return valves is an essential part of your Porsche’s engine ventilation system. Designed to OEM specifications, they regulate crankcase pressure, prevent oil vapour backflow, and ensure smooth, efficient engine operation. Replacing both valves together restores proper crankcase breathing and protects your engine from leaks and excess oil consumption.

Fits:

  • Porsche Cayenne V6 3.6L Petrol 300Hp
  • Porsche Panamera S V6 Turbo 3.0L 2WD (420Hp)
  • Porsche Panamera S V6 Turbo 3.0L 2WD Executive
  • Porsche Panamera 4S V6 Turbo 3.0L 4WD (420Hp)
  • Porsche Panamera 4S V6 Turbo 3.0L 4WD Executive
  • Porsche Macan S Petrol 3.0L V6 340Bhp

What the Non Return Valves Do

  • Maintain Correct Pressure: Allow gases to escape while preventing backflow into the crankcase.
  • Improve Engine Efficiency: Reduce oil vapour re-entry, helping cleaner combustion.
  • Protect Components: Prevent pressure build-up that can damage seals and gaskets.

Symptoms of Faulty Breather Valves

  • Excessive oil consumption.
  • Blue smoke from the exhaust.
  • Oil leaks around gaskets and seals.
  • Rough idle, misfires, or poor performance.
  • Strong smell of oil fumes in the engine bay or cabin.

Common Reasons for Failure

  • Oil Sludge & Contamination: Causes the valve to stick open or closed.
  • Rubber & Spring Wear: Degradation over time reduces effectiveness.
  • Lack of Maintenance: Old oil accelerates valve failure.
  • High Mileage Stress: Heat cycles and pressure changes weaken components.

Why Replace?
Restores proper crankcase ventilation.
Prevents oil leaks and excess pressure in the engine.
