Diagram ref no 9
The camshaft chain housing contains the timing chains that synchronise crankshaft and camshaft rotation. A correctly sealing chain cover gasket is essential for retaining engine oil within the chain housing, ensuring continuous lubrication of the timing chains, sprockets and tensioners while preventing oil contamination of the engine exterior.
Whether you're carrying out an engine rebuild, repairing an oil leak or restoring an early short-wheelbase Porsche 911, this OE Match gasket provides factory-quality fitment and reliable sealing performance.
What Does the Camshaft Chain Cover Gasket Do?
The chain cover gasket seals the mating surfaces between the camshaft chain housing and the outer chain cover.
Its primary functions include:
- Preventing engine oil leaks.
- Maintaining correct oil levels within the chain housing.
- Protecting timing chains and sprockets with continuous lubrication.
- Preventing dirt and moisture entering the timing case.
- Supporting long-term engine reliability.
- Maintaining a clean engine bay.
A properly sealing gasket is essential for preserving the lubrication and protection of the Porsche flat-six timing system.
Why Does the Chain Cover Gasket Fail?
Over many years of service, engine gaskets naturally deteriorate due to constant exposure to oil, heat and engine vibration.
Common causes of failure include:
- Age-related hardening.
- Compression set.
- Heat cycling.
- Oil saturation.
- Damage during previous repairs.
- Incorrect installation or overtightening.
- Engine rebuilds requiring gasket replacement.
Replacing the gasket whenever the chain cover is removed is considered best practice.
Symptoms of a Failing Chain Cover Gasket
Common signs include:
- Oil leaks around the right-hand chain housing.
- Oil residue on the engine casing.
- Oil dripping beneath the vehicle.
- Burning oil smell from oil contacting hot exhaust components.
- Dirt collecting around oil seepage.
- Visible gasket deterioration during servicing.
Ignoring oil leaks can lead to reduced oil levels and contamination of surrounding engine components.
When Should the Camshaft Chain Cover Gasket Be Replaced?
Replacement is recommended when:
- The chain housing cover is removed.
- Engine oil leaks are present.
- Performing a timing chain inspection.
- Carrying out a complete engine rebuild.
- Restoring a classic Porsche engine.
- Replacing timing chains, sprockets or tensioners.
Installing a new gasket during reassembly helps ensure a long-lasting, leak-free repair

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.
