This Oil Separator, Left is a OE MATCH Porsche 971.1 / 971.2 Panamera engine component designed to regulate crankcase ventilation by separating oil vapour from blow-by gases before they are recirculated into the intake system. Positioned on the left side of the engine, this unit ensures clean airflow while preventing excess oil from entering the combustion process.

- Porsche 957 Cayenne Turbo / Turbo S 4.8L 2007-10
OE Match connecting vent line for the air/oil separators. This breather component forms part of the engine’s crankcase ventilation system.
Fits:
- Porsche 957 Cayenne Turbo / Turbo S 4.8L 2007-10
Diagram Ref No 19
Check fitment for your specific vehicle (model, year, engine) before ordering.
What This Product Does
The line provides the connection linking the air/oil separators, allowing ventilation gases to pass through this part of the breather assembly. It is a connecting pipe, rather than an oil separator or non-return valve.
Functions
- Connects the air/oil separator assemblies.
- Provides a passage for crankcase ventilation gases.
- Supports the intended routing of the engine breather system.
Technical Details
- Brand: OE Match.
- Internal diagram description: breather line.
- Diagram engine/model identifier: 4851.
Symptoms of Fault
Inspection is appropriate if the line becomes brittle, develops cracks or shows oily deposits around its connections. Rough idling, unusual breather noises or increased oil use can also accompany ventilation faults, but do not establish that this line is the cause.
Why Replacement Matters
Renewing a damaged connecting line helps restore a sealed ventilation path. Check the neighbouring breather pipes, connections and separator assemblies during diagnosis rather than assuming every ventilation symptom requires this component.
