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.

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.

OEMatch Crankshaft & Parts — Fit, Function, Confidence
OEMatch supplies crankshaft and related engine parts for Porsche models, selected for rebuilds, restorations and major servicing. The range is described to help you identify bearings, seals, fastenings and assembled crankshafts needed to complete an overhaul while preserving engine balance and lubrication integrity.
Available Types
- Complete crankshafts
- Main and rod bearings
- Thrust washers and spacers
- Oil seals and gaskets
- Dowel pins, bolts and pulleys
Understanding OEMatch Crankshaft & Parts
OEM (Original Equipment Manufacturer) parts are made by the same company that produced your Porsche’s original crankshafts and parts.
OE (Original Equipment) refers to parts matching original specifications for the crankshafts and parts and may be supplied by alternative manufacturers. Aftermarket parts offer alternative options, sometimes with enhanced features or better value. OEMatch supplies non-OEM crankshafts and parts engineered as direct-fit alternatives to OEM parts, made to original-spec dimensions and tolerances for Porsche models.
OEMatch provides a wide range of crankshafts and related engine hardware for Porsche applications, supporting repairs across multiple model generations. The crankshaft converts linear piston motion into rotational energy and relies on bearings, seals and correct fastenings to maintain alignment, oil flow and rotational balance.
Benefits Include
- Restores rotational balance and smooth power delivery
- Protects bearings and journals by restoring correct clearances
- Improves oil control and sealing to reduce contamination and wear
Why Crankshaft & Parts Wear and Fail
- Oil starvation or contamination leading to bearing wear and journal scoring
- Imbalance or damaged dampers causing vibration and accelerated fatigue
- Cracks or fatigue from high loads, detonation or extended high-RPM use
- Incorrect assembly torque or alignment during rebuilds
The Importance of Replacing with OEMatch Crankshaft & Parts
Replacing worn crankshaft elements with correctly specified parts restores bearing clearances, oil control and rotational balance that are essential to long-term engine function in Porsche models. Choosing parts described for crankshaft assemblies helps reduce the risk of secondary damage, supports reliable lubrication and aids a smoother, more consistent running engine after rebuild or repair.
Advantages
- Direct-fit alternatives engineered to match original dimensions and tolerances where applicable
- Coverage aimed at classic and modern Porsche engines to support rebuilds and preventive maintenance
- Parts described for clear identification during overhaul and reassembly
