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

Typical Applications
Hylomar Gasket 3400 can be used as a gasketing compound between machined surfaces. It is ideal for sealing between mating faces on engines and transmission components where resistance to temperature and vibration are essential.
INSTRUCTIONS FOR USE
Hylomar Gasket 3400 should be applied to clean and dry surfaces, free of contamination such as oil or grease. The compound may be dispensed by hand from cartridge, concertina pack, or via a screen printing system. Once applied the joint should be assembled as soon as practical. Any excess compound can be easily wiped off external surfaces with a clean cloth soaked in Acetone or other suitable solvents.
