Timing covers and gaskets
This set of 18 rubber sealing rings (thrust rings) is used in the timing-chain assembly of Porsche 911 (964) and 911 (993) models. Each seal is manufactured to the same dimensions, material quality, and performance standards as the original Porsche part, ensuring perfect OE fit and reliable sealing around the timing-chain cover studs and bolts.
Fits:
Porsche 964 - 1989 to 1994
Porsche 964 turbo 3.6ltr - 1991 to 1994
Porsche 993 - 1994 to 1997
Diagram ref no 17
• Includes: Set of 18 rubber sealing plugs – enough for one vehicle.
• Position: Located on the timing-chain cover / chain case, around stud or bolt interfaces.
• Function: Provides a secure oil-tight seal at the stud/bolt interface, preventing oil leaks and blocking moisture or dirt ingress into the chain case.
Over time, rubber seals can harden or deform from heat and oil exposure, leading to minor leaks or contamination in the chain-case area. Replacing all seals during engine service or overhaul ensures optimal sealing integrity and proper lubrication of timing components.
Recommended Replacement:
• Whenever the timing-chain cover or chain-case is removed or serviced.
• When oil seepage or residue is visible around chain-case bolts or studs.
• During carburettor or gasket replacement, or any full engine rebuild.
• When replacing timing components to ensure complete reassembly sealing.

• 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.

Timing Covers & Gaskets – Protect Your Porsche’s Engine Timing System
The timing cover and its gasket play a crucial role in your Porsche’s engine reliability. These components seal the timing system — protecting the timing chain, gears, and belt from oil leaks, debris, and contaminants. A secure timing cover ensures proper lubrication, maintains internal oil pressure, and prevents costly engine damage caused by fluid loss or contamination.
At Design911, we supply a wide range of timing covers and gaskets suitable for Porsche models old and new. Manufactured using high-grade aluminium, composite materials, and heat-resistant rubber compounds, our products are designed to withstand vibration, temperature extremes, and oil exposure while providing a perfect, leak-free fit.
Whether you’re maintaining a classic air-cooled 911 or rebuilding a high-performance GT engine, our timing covers and gasket sets deliver exceptional durability, sealing performance, and reliability.
What Do Timing Covers & Gaskets Do?
The timing cover shields the engine’s timing components and works in tandem with its gasket to maintain a clean, sealed environment.
Core Functions:
- Protect
the timing chain and gears from dirt, debris, and oil contamination.
- Prevent
oil leaks by sealing the timing section from external elements.
- Maintain
proper oil pressure in the engine.
- Assist
in heat dissipation around the timing assembly.
- Ensure long-term reliability of moving components like the camshaft and crankshaft.
A properly sealed timing cover is essential for consistent performance and preventing internal wear caused by oil leaks or debris infiltration.
Why Do Timing Covers & Gaskets Fail?
Due to constant exposure to oil, heat, and vibration, timing covers and gaskets can degrade or crack over time — leading to oil leaks and reduced performance.
Common Causes of Failure Include:
- Gasket
hardening or shrinkage from prolonged heat exposure.
- Cracked
or warped covers from over-tightening or impact.
- Oil
leaks caused by poor sealing or material fatigue.
- Contaminant
build-up inside the timing housing.
- Improper gasket installation or uneven torque during servicing.
Symptoms of failure include visible oil leaks at the front of the engine, oil dripping under the timing chain cover, or low oil levels. Ignoring these issues can lead to costly timing component wear or engine failure.
Why Replace Components?
Replacing worn or leaking timing covers and gaskets ensures your Porsche’s timing system remains protected and properly lubricated. Our high-performance replacement parts are designed for exact fitment, durability, and long-term sealing efficiency.
