Diagram ref no 17

• 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.
