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:

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.
