Information
Rear Main Crankshaft Oil Seal.
The Genuine Porsche Rear Main Crankshaft Oil Seal is an original equipment engine sealing component designed to provide a reliable oil-tight seal between the rear of the crankshaft and the engine block on compatible Porsche engines. Manufactured to Porsche's exact specifications for fit, sealing performance and durability, this rear main seal prevents engine oil from escaping at the crankshaft exit point while allowing smooth crankshaft rotation, ensuring optimum lubrication and long-term engine reliability.
Fits:
Diagram Ref No 39
Manufactured from premium heat-resistant elastomer with a precision-moulded sealing lip and reinforced outer casing, the seal is engineered to withstand high crankshaft speeds, continuous thermal cycling, elevated oil temperatures and prolonged exposure to engine oil. Designed as a direct replacement for the original component, it provides factory-correct fitment and dependable sealing performance, making it ideal during clutch replacement, engine rebuilds or preventative maintenance.

Designed as a direct replacement for the original component, it provides factory-correct fitment and dependable sealing performance, making it ideal during clutch replacement, engine rebuilds or preventative maintenance.
What This Product Does:
- Prevents engine oil from leaking from the rear of the crankshaft.
- Maintains the integrity of the engine lubrication system.
- Provides a durable seal while allowing smooth crankshaft rotation.
- Helps protect the flywheel and transmission bell housing from oil contamination.
- Prevents dirt and moisture from entering the engine.
- Supports reliable engine lubrication and performance.
- Restores factory sealing performance.
- Forms an essential part of the engine sealing system.
Symptoms Of Wear Or Failure:
- Engine oil leaking between the engine and transmission.
- Oil spots beneath the rear of the engine.
- Burning oil smell caused by oil contacting hot components.
- Oil contamination inside the bell housing.
- Clutch slipping due to oil contamination (manual transmission models).
- Gradual engine oil loss.Hardened, cracked or worn sealing lip.
- Excessive oil residue around the rear of the engine.
- Persistent oil leaks despite replacing nearby gaskets.
- Reduced engine reliability due to oil loss.
Why Replacement Matters:
- The rear main crankshaft oil seal operates in one of the most demanding areas of the engine, 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, wear or lose elasticity, allowing engine oil to escape.
- A leaking rear main seal can contaminate the flywheel, clutch assembly or transmission bell housing, potentially leading to clutch slippage, increased repair costs and reduced engine lubrication. If left unresolved, continued oil loss can accelerate internal engine wear and compromise long-term reliability.
- Replacing a worn rear main crankshaft oil seal with a Genuine Porsche component restores factory sealing performance and helps ensure dependable engine protection. Manufactured to Porsche's exact standards, the Genuine Rear Main Crankshaft Oil Seal provides precise fitment, superior sealing efficiency and long-lasting durability, maintaining the performance, reliability and quality expected from your Porsche.
