This set provides everything needed to securely reseal the front of your engine. Alongside the oil seals, it includes replacement spacer rings, as the original ones often wear down from contact with the shaft seal lip and require replacement. The set also comes with O-rings and a camshaft both that needs to be replaced.

The timing section of the Porsche 944/968 engine contains critical rotating components including the camshaft, balance shafts and crankshaft, all protected by covers and seals at the front of the engine. The OE Match dust seal and gasket set provides the sealing elements required when servicing this area.
The kit includes seals and gaskets designed to prevent contamination and leakage around the timing housing. These components are typically replaced during timing belt service, front engine resealing or engine rebuild work.
High-quality gasket materials are used to withstand the temperature, oil exposure and mechanical stresses present in performance engines.
Function
• Leak Prevention: Seals the front timing housing to prevent oil leakage
• Component Protection: Keeps dust and debris away from timing components
• Engine Reliability: Supports proper operation of camshaft and balance shafts
• Service Solution: Ideal for timing belt replacement or front engine rebuild
Seals and gaskets around the timing assembly are exposed to heat, oil and constant engine vibration. Over time these components can harden, crack or lose elasticity, leading to oil leaks or contamination of the timing area. Replacing them during maintenance helps protect the timing components and maintain engine reliability.
Consider replacing the timing dust seal and gasket set when:
• Performing a timing belt replacement
• Rebuilding or resealing the front of the engine
• Oil leaks appear from the timing cover area
• Old seals show cracking or deterioration

OEMatch Radial Seal / RMS / Camshaft / Balance shaft — Durability, Sealing, Performance
For Porsche models, radial oil seals including rear main, camshaft, crankshaft and balance shaft seals keep lubricating oil contained, exclude contaminants and protect rotating components. Regular inspection and correct replacement reduce leakage risk, help maintain oil pressure and support long service life during routine maintenance or engine rebuilds.
Available Types
- Rear main seal
- Crankshaft seal
- Camshaft seal
- Balance shaft seal
Understanding OEMatch Radial Seal / RMS / Camshaft / Balance shaft
OEM (Original Equipment Manufacturer) parts are made by the same company that produced your Porsche’s original radial seals.
OE (Original Equipment) refers to parts matching original specifications for the radial seals and may be supplied by alternative manufacturers. Aftermarket parts offer alternative options, sometimes with enhanced features or better value. OEMatch supplies non-OEM radial seals engineered as direct-fit alternatives to OEM parts, made to original-spec dimensions and tolerances for Porsche models.
Radial seals form a lip contact against rotating shafts to retain oil and exclude dirt and moisture. They are typically made from elastomeric materials combined with a metal case and a spring to maintain sealing pressure. Selection of the correct seal material and design is important to resist heat, oil contamination and shaft speed seen in Porsche engines.
Benefits Include
- Restores reliable oil containment and helps maintain correct oil pressure
- Protects bearings, housings and timing components from contamination
- Materials selected to resist heat, oil and ageing where applicable
Why Radial Seal / RMS / Camshaft / Balance shaft Wear and Fail
- Age-related hardening and loss of elastomer flexibility
- Excessive crankcase pressure or blocked breathers forcing oil past the lip
- Oil contamination or chemical degradation of the seal material
- Incorrect installation, misalignment or damaged sealing faces
The Importance of Replacing with OEMatch Radial Seal / RMS / Camshaft / Balance shaft
Addressing worn or leaking seals promptly prevents progressive oil loss and contamination that can damage bearings, camshaft journals and crankcases. Correct replacement restores sealing integrity during service or rebuild work and reduces the chance of secondary damage or repeated repairs. Choosing seals suitable for Porsche engine conditions supports consistent lubrication and reduces workshop time diagnosing recurrent leaks.
Advantages
- Direct-fit replacements engineered to match original dimensions and tolerances where applicable
- Options selected for compatibility with Porsche engine layouts and service procedures
- Variety of seal types to cover rear main, crankshaft, camshaft and balance shaft applications
