What the Products Do

• Cam Cover Gaskets: Seal the camshaft/valve covers to the cylinder head, preventing engine oil leaks and keeping contaminants out.
• Bolts: Maintain correct torque and clamping pressure on the covers, ensuring the gaskets stay sealed under heat and vibration.

Together, they protect your engine from oil leaks, maintain lubrication, and preserve long-term engine health.

Symptoms of Failure

• Visible oil leaks around the cam/valve cover area
• Burning oil smell from oil dripping onto exhaust components
• Oil spots under the car after parking
• Low oil levels or frequent top-ups
• Rough running or misfires caused by oil leaking into spark plug wells

Common Reasons for Failure

• Age & Heat: Gaskets harden and lose flexibility after years of heat cycling.
• Oil Exposure: Continuous contact with hot oil degrades gasket material.
• Bolt Stretch or Loosening: Original bolts lose clamping force over time, allowing leaks.
• Improper Previous Repair: Reusing old bolts or over-tightening can warp covers and damage seals.

Why Replace as a Kit?

• Ensures complete resealing of both cam covers in one service.
• New bolts guarantee proper torque and sealing pressure.
• Prevents oil leaks that can cause engine bay mess, smoke, or fire hazards.
• Protects against premature engine wear from low oil levels.
• Saves on labour by replacing all related components at once.

Ideal For: Routine maintenance, leak repair, or as a preventive upgrade during top-end engine service.
