Crankshaft Seal With Flange.
The OE Match Crankshaft Seal with Flange is a premium-quality replacement engine sealing assembly designed to provide a reliable oil-tight seal at the crankshaft while ensuring accurate installation and alignment on compatible Porsche engines. Manufactured to OE specifications for fit, sealing performance and durability, this integrated seal and flange assembly prevents engine oil leaks while simplifying installation and maintaining precise positioning of the crankshaft seal.  

Fits:
  • Porsche 958 Cayenne S V6 3.0L Hybrid (380Hp) 2010-17
  • Porsche 970.1 Panamera S Hybrid V6 3.0L 2011-13
  • Porsche 970.2 Panamera S E-Hybrid V6 3.0L (416Hp) 2014-16  

Diagram Ref No 25

Manufactured from high-quality heat-resistant elastomer bonded to a precision-machined flange housing, the assembly is engineered to withstand high crankshaft speeds, continuous thermal cycling, elevated engine temperatures and prolonged exposure to engine oil. Designed for direct OE-style installation, the integrated flange ensures correct seal alignment and consistent sealing pressure, making it the ideal replacement during engine rebuilds, major servicing or when repairing oil leaks at the crankshaft.  

What This Product Does:
  • Prevents engine oil from leaking around the crankshaft.
  • Provides an integrated crankshaft seal and mounting flange.
  • Maintains the integrity of the engine lubrication system.
  • Ensures accurate seal alignment during installation.
  • Allows smooth crankshaft rotation while maintaining an effective seal.
  • Protects the engine from oil loss and contamination.
  • Restores factory sealing performance.
  • Forms an essential part of the engine sealing system.

Symptoms Of Wear Or Failure:
  • Engine oil leaking from the crankshaft area.
  • Oil spots beneath the vehicle after parking.
  • Oil contamination around the engine or transmission bell housing.
  • Burning oil smell caused by oil contacting hot engine or exhaust components.
  • Gradual engine oil loss.
  • Visible deterioration of the sealing lip.
  • Warped or damaged flange housing.
  • Persistent oil leaks despite replacing nearby gaskets.
  • Oil contamination of the flywheel or clutch assembly where applicable.
  • Reduced engine reliability due to ongoing oil leakage.

Why Replacement Matters:

  • The crankshaft seal and flange assembly operates under demanding conditions, sealing against a continuously rotating crankshaft while being exposed to high temperatures, oil pressure and constant thermal cycling. Over time, the sealing lip can harden or wear, while the flange may become damaged or distorted, reducing sealing effectiveness.
  • A leaking crankshaft seal can result in engine oil loss, contamination of surrounding components and, depending on its location, oil reaching the flywheel or clutch assembly. Continued operation with a leaking seal can reduce engine lubrication, accelerate internal wear and lead to costly engine or transmission repairs.
  • Replacing a worn or damaged crankshaft seal with flange restores the engine's sealing integrity and ensures precise seal alignment for long-term reliability. The OE Match replacement provides factory-style fitment, premium-quality materials and durable construction, helping maintain correct oil pressure, prevent leaks and preserve the performance and reliability expected from your Porsche.
