Product Information
Product Information
Rear Main Crankshaft Oil Seal, 85 x 105 x 11.
The OE Match Rear Main Crankshaft Oil Seal, 85 x 105 x 11mm is a premium-quality replacement engine sealing component designed to prevent engine oil from leaking where the crankshaft exits the rear of the engine and connects to the flywheel or flexplate assembly on compatible Porsche models. Manufactured to OE specifications for fit, sealing performance and durability, this precision-engineered seal helps maintain correct engine oil retention while protecting the clutch or transmission bell housing from oil contamination.  

Fits:
  • Porsche 955 Cayenne 3.2L V6 2003-06
  • Porsche 957 Cayenne 3.6L 2007-10
  • Porsche 958 Cayenne V6 3.6L Petrol (300Hp) 2010-17  

Diagram Ref No 11

Manufactured from premium oil-resistant fluoroelastomer (FKM) rubber with a precision-moulded sealing lip, integrated tension spring and reinforced metal outer casing, the seal is engineered to withstand high crankshaft speeds, continuous engine oil exposure, elevated operating temperatures and repeated thermal cycling. Designed for direct OE-style installation, it provides a secure, leak-free seal and is ideal for engine rebuilds, clutch replacements and preventative maintenance.  

What This Product Does:
  • Seals the rear of the crankshaft to prevent engine oil leaks.
  • Maintains engine oil pressure and lubrication.
  • Prevents oil contamination of the flywheel, flexplate or clutch assembly.
  • Protects the transmission bell housing from oil ingress.
  • Helps maintain engine reliability and cleanliness.
  • Supports efficient long-term engine operation.
  • Restores factory sealing performance.
  • Forms an essential part of the engine lubrication system.

Symptoms Of Wear Or Failure:
  • Engine oil leaking from the rear of the engine.
  • Oil spots beneath the vehicle.
  • Low engine oil level requiring frequent topping up.
  • Burning oil smell caused by oil contacting hot engine or exhaust components.
  • Oil contamination inside the transmission bell housing.
  • Clutch slipping or clutch judder on manual transmission models due to oil contamination.
  • Visible oil residue around the crankshaft or gearbox mating area.
  • Excessive oil consumption caused by leakage.
  • Engine bay or underbody oil contamination.
  • Premature wear of clutch or transmission components.

Why Replacement Matters:

  • The rear main crankshaft oil seal is subjected to continuous contact with the rotating crankshaft while being exposed to hot engine oil, vibration, crankcase pressure and repeated heat cycles. Over time, the sealing lip can wear, while the rubber material may harden, shrink or crack, reducing its ability to maintain an effective seal.
  • A leaking rear main seal can result in progressive engine oil loss and contamination of the flywheel, clutch or transmission components. On manual transmission vehicles, oil contamination of the clutch can cause slipping, judder and premature clutch failure, leading to significantly higher repair costs if left unresolved.
  • Replacing a worn or damaged rear main seal restores the integrity of the engine lubrication system and prevents costly oil leaks. The OE Match Rear Main Crankshaft Oil Seal, 85 x 105 x 11mm is manufactured to OE standards using premium-quality oil-resistant materials, providing factory-style fitment, exceptional sealing performance and long-lasting durability, ensuring the reliability, protection and performance expected from your Porsche.
