038 103 085C – Camshaft / Crankshaft Seal – (Priced Each)

Description

The 038103085C Seal is a critical engine component that prevents oil from escaping the cylinder head or block at the camshaft and crankshaft exit points. This 038103085C Seal features the updated PTFE (Polytetrafluoroethylene) lip design, which eliminates the traditional metal spring found in older seal generations. Consequently, this modern design offers superior thermal stability and lower friction during high-speed engine operation.

Proper sealing at the camshaft and crankshaft is vital for maintaining internal oil pressure and preventing external contamination. Furthermore, this seal is engineered to withstand the constant rotation and high temperatures associated with the engine’s timing system. Therefore, choosing a high-quality 038103085C Seal helps protect your timing belt from oil soak and ensures the engine remains properly lubricated.

Why the 038103085C Seal Matters

The camshaft and crankshaft are responsible for the mechanical timing of your vehicle. If the 038103085C Seal fails, however, pressurized engine oil can leak onto the timing belt or serpentine belt. Consequently, the rubber belt material can degrade rapidly, leading to belt slippage or catastrophic timing failure, which often results in internal engine damage.

Additionally, this updated PTFE design requires specific handling because it lacks a tensioning spring. Moreover, the material relies on a “memory” effect to form a perfect bond with the metal surface. Replacing a leaking seal with this genuine-specification part restores factory-level integrity to your engine’s lubrication system while reducing the risk of environmental oil contamination.

Signs of Failure

Inspect your vehicle for these symptoms of a failing camshaft or crankshaft seal:

• Oil pooling on the floor directly beneath the front or rear of the engine.

• Visible oil residue or “wetness” around the timing cover or crankshaft pulley.

• Oil contamination on the timing belt, which can cause it to swell or skip teeth.

• Burning oil smells coming from the engine bay as oil reaches hot components.

• Unexpectedly low engine oil levels between scheduled service intervals.

• Excessive dirt and grime buildup on the front of the engine block.

Key Features — 038103085C Seal

• OE Part Number: 038 103 085 C

• Design: Modern PTFE sealing lip without an internal garter spring.

• Function: Seals the camshaft or crankshaft to prevent engine oil loss.

• Performance: Reduced friction and enhanced resistance to chemical degradation.

• Compatibility: Fits a wide range of Volkswagen and Audi 4-cylinder engines.

• Application: Used as either a camshaft seal or front crankshaft seal (select models).

Service Notes

Always verify fitment by VIN before ordering. PTFE seals require a specific installation procedure that differs from traditional rubber seals. Failure to follow these steps will result in immediate leakage. Furthermore, the mating surfaces on the camshaft or crankshaft must be inspected for grooves or scoring that could prevent a proper seal.

Compatibility

Always verify fitment by VIN before ordering. This 32x47x10mm seal is used extensively in TDI and early gasoline engines.
