- Porsche 957 Cayenne Turbo / Turbo S 4.8L 2007-10
Crankcase Ventilation Seal
Sold each
Fits
- Porsche 957 Cayenne Turbo / Turbo S 4.8L, 2007–2010
What This Product Does
The gasket closes a joint associated with the oil separator and crankcase breather assembly. An intact seal helps contain oil residue and vapour while limiting unintended air leakage at that connection. It is a sealing component, not a complete separator or breather line.
Functions
- Provides sealing at the associated ventilation joint.
- Helps contain crankcase vapour within its intended route.
- Limits seepage and unintended air entry where the components meet.
Technical Details
- Porsche genuine replacement component.
- Product identification: 94810743750.
- Diagram description: Seal; component also described as a gasket.
- Assembly coverage identifies models 4801 and 4851.
- The supplied seal row specifies model 4851.
- Diagram requirement for model 4851: four seals. This is an assembly quantity, not a stated pack quantity.
Symptoms of Fault
- Localised oily deposits at the sealing joint.
- A gasket showing brittleness, cracking or permanent compression.
- Air leakage detected around the breather connection.
- Uneven idling associated with a confirmed ventilation leak.
- An oily smell accompanied by deposits near adjacent connections.
These signs warrant inspection but do not identify this gasket as the cause on their own. Check nearby hoses, connections and the separator before choosing replacement parts.
Why Replacement Matters
Repeated heating and cooling, together with ageing and oil exposure, can affect a gasket's sealing ability. Renew a damaged or compressed seal during ventilation-system repairs rather than refitting it. Inspect the contact surfaces, breather pipes and retaining components at the same time; replacing the gasket alone will not correct damage elsewhere in the assembly.
FAQs
- Does this include a complete separator?
No. The product is a seal or gasket; associated ventilation components are separate items. - What does the diagram quantity mean?
The row records four seals against model 4851. Confirm how many your particular repair requires. - When should an existing gasket be renewed?
Replace it if inspection reveals hardening, distortion, contamination or damage following removal. - What should I check before selecting it?
Match 94810743750 to your vehicle identification number, engine specification and production year, retaining the diagram's model-specific note.
