- 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.

OE Match air / oil separator for selected Porsche 958 Cayenne and 970 Panamera models.
A gasket is included with the separator.
Fits:
Porsche 958 Cayenne S 4.8L / GTS 4.8L 2011 - 2014
Porsche 958 Cayenne Turbo 4.8L 2011 - 2018
Porsche 970 Panamera 3.6L 2011 - 2016
Porsche 970 Panamera S 4.8L 2010 - 2013
Porsche 970 Panamera GTS 4.8L / Turbo 4.8L 2010 - 2016
Diagram ref no 1
What This Product Does
The separator removes suspended oil from crankcase ventilation gases before those gases pass towards the intake. It also supports the engine’s crankcase pressure-control system; Porsche technical information identifies a relationship between incorrect crankcase vacuum and increased oil consumption on affected Cayenne engines. ([static.nhtsa.gov](https://static.nhtsa.gov/odi/tsbs/2013/SB-10051876-9608.pdf))
Functions
- Separates oil mist from engine breather gases.
- Limits oil carry-over into the intake.
- Supports controlled crankcase ventilation.
Technical Details
- Brand: OE Match.
- Supplied part reference: 94810713522.
- Gasket included.
Symptoms of Fault
Possible signs include increased oil use, exhaust smoke, uneven idling, unusual breather noises or oil deposits around the intake. These symptoms require diagnosis rather than automatically identifying the separator as faulty. Porsche also documents that a leaking separator can admit unwanted air and trigger the engine warning light on affected vehicles. ([static.nhtsa.gov](https://static.nhtsa.gov/odi/tsbs/2013/SB-10051876-9608.pdf))
Why Replacement Matters
Renewing a confirmed faulty separator addresses defective oil separation or crankcase ventilation. Check connected breather pipes, sealing surfaces and oil level during diagnosis so that related faults are not overlooked.
FAQs
Is a gasket supplied?
Yes, this OE Match separator includes a gasket.
Does exhaust smoke always indicate separator failure?
No. Oil overfill and other engine faults can produce similar symptoms, so establish the cause before replacing parts.
What should be checked before fitting?
Confirm the vehicle’s engine and application details, then inspect the adjoining ventilation pipes and connections.

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
