The kit comprises critical crankcase ventilation parts used in high-performance Porsche engines to separate oil from air in the crankcase breather circuit and return clean air back into the intake system. The air/oil separator captures oil mist and blow-by gases that form in the crankcase, preventing oil from entering the intake while ensuring the engine breathes correctly under load. The breather hoses are OE Match-engineered flexible tubes that connect the separator to the crankcase and intake ports, maintaining correct airflow paths and preventing vacuum leaks.
This complete kit allows for a professional service of the crankcase ventilation system in one go, ensuring proper sealing and restored functionality.
The air/oil separator collects and filters blow-by vapours that form during combustion, separating oil droplets from the air and returning them to the crankcase. This prevents oil consumption, reduces smoky exhaust and keeps the intake tract clean. It also regulates crankcase pressure so that seals, gaskets and piston rings remain protected.
The crankcase breather hoses maintain the pathways between engine crankcase ports and the separator, ensuring smooth, controlled airflow and preventing oil-laden air from contaminating intake components. Without functioning hoses, vacuum leaks and crankcase pressure imbalances can occur, leading to poor engine performance and increased oil spray inside the engine compartment.
Over time, the air/oil separator and breather hoses can clog with oil residue, harden, crack, or lose their ability to properly separate oil from air — especially on high-mileage engines or vehicles subjected to frequent high RPM use.
Failure of these components can lead to:
• Increased oil consumption and smoky exhaust
• Contamination of the intake and turbocharger with oil mist
• Erratic crankcase pressure, leading to gasket leaks
• Poor idle quality or check engine codes related to crankcase pressure
Replacing them with this OE Match kit helps restore correct crankcase ventilation system performance, protects your engine internals and maintains smooth engine operation.
Replace the air/oil separator kit if you notice any of the following:
• Visible oil residue around the separator or hoses
• Excessive oil consumption
• Smoke or oil smell from the tailpipe
• Engine runs poorly at idle or under load
• Fault codes pointing to crankcase pressure issues
• Hose cracks, split rubber, or visibly brittle components
