The rubber sealing ring (thrust ring) used in the timing-chain assembly of Porsche 911 (964) and 911 (993) models. Its manufactured to the same dimensions, material quality, and performance standards as the original Porsche part. It installs directly without modification, restoring a perfect seal around the timing-chain cover studs/bolts.

• Position: It is located on the timing-chain cover / chain case, around stud/bolt interfaces.
• Function: Provides a tight seal around the stud/bolt interface of the timing-chain cover or chain-case, preventing oil escape and blocking the ingress of dirt or moisture.
Over time, rubber seals degrade (due to heat, oil exposure, age) and lose their ability to keep a perfect seal. When this ring is worn or flattened, oil can seep or leak from the chain-case cover, or contaminants may ingress. A leak here may lead to oil loss, dirty chain-case internals, poor lubrication of the chain or guides, and increased wear or noise in the timing system.
Replace this rubber sealing when:
• Whenever the timing-chain cover or chain-case is removed or serviced.
• If you observe oil seeping from around the cover bolt/stud area, or notice oil spots, chain case cover looseness or cover gasket replacement being unavoidable.
• As part of routine engine rebuilds or maintenance where timing cover is accessed.
• When performing an engine overhaul or replacing timing components – replacing all seals ensures full integrity upon reassembly.

Engine
Cam Cover Gasket & Bolt Kit
This kit includes both engine cam cover gaskets and the correct replacement
bolts providing a complete solution for resealing your engine’s cam covers.
Designed to OEM specifications, the gaskets prevent oil leaks, while the fresh
hardware ensures a secure and lasting seal. Replacing both gaskets and bolts
together avoids repeat labour and guarantees long-term reliability.

What the
Products Do
- Cam Cover Gaskets: Seal the camshaft/valve covers to the cylinder head, preventing engine oil leaks and keeping contaminants out.
- Bolts: Maintain correct torque and clamping pressure on the covers, ensuring the gaskets stay sealed under heat and vibration.
Together, they protect your engine from oil leaks, maintain lubrication, and preserve long-term engine health.
Symptoms of
Failure
- Visible oil leaks around the cam/valve cover area
- Burning oil smell from oil dripping onto exhaust components
- Oil spots under the car after parking
- Low oil levels or frequent top-ups
- Rough running or misfires caused by oil leaking into spark plug wells
Common
Reasons for Failure
- Age & Heat: Gaskets harden and lose flexibility after years of heat cycling.
- Oil Exposure: Continuous contact with hot oil degrades gasket material.
- Bolt Stretch or Loosening: Original bolts lose clamping force over time, allowing leaks.
- Improper Previous Repair: Reusing old bolts or over-tightening can warp covers and damage seals.
Why Replace
as a Kit?
- Ensures complete resealing of both cam covers in one service.
- New bolts guarantee proper torque and sealing pressure.
- Prevents oil leaks that can cause engine bay mess, smoke, or fire hazards.
- Protects against premature engine wear from low oil levels.
- Saves on labour by replacing all related components at once.
Ideal For: Routine
maintenance, leak repair, or as a preventive upgrade during top-end engine
service.
