What This Sealing Grommet Does

The sealing grommet sits around the cam cover fixing points, creating a tight seal between the fastener and the cam cover.

It helps:

• Prevent oil leaks from bolt fixing points
• Maintain correct pressure on the cam cover gasket
• Absorb vibration and movement
• Support even load distribution across the cam cover
• Improve overall sealing reliability

Why Sealing Grommets Fail

Due to constant exposure to heat and oil, grommets degrade over time.

Common causes include:

• Heat cycling causing hardening and shrinkage
• Oil exposure breaking down rubber material
• Compression fatigue from repeated tightening
• Age-related brittleness and cracking

Symptoms of a Worn Grommet

• Oil seepage around cam cover bolts
• Visible deterioration or cracking
• Reduced gasket sealing effectiveness
• Oil residue on top of the engine

Replacing grommets during maintenance helps prevent recurring leaks.

Why You May Need to Replace This Grommet

• Eliminate oil leaks at fixing points
• Ensure proper gasket sealing
• Restore correct cam cover pressure distribution
• Ideal when replacing cam cover gaskets
• Low-cost component that prevents larger issues
