When to Replace the Valve Cover Gasket?

• Visible oil leaks around the valve cover or exhaust manifold
• Burning oil smell after engine start
• Oil in spark plug wells – typical symptom of worn spark plug seals
• Oil seepage at the head corners or near the dipstick area

Regular replacement of the valve cover gasket helps maintain a clean engine bay, prevents carbon buildup, and keeps rubber components flexible for long-lasting sealing. It’s recommended to replace the gasket whenever the cover is removed or every 100,000 km.
