Why replacement matters.
Common Issues with Old / Failing Gaskets:
• With age, heat cycles, vibration, and exposure to oil and chemicals, the gasket material (often a composite rubber, elastomer, or multi-layer seal) can degrade, becoming brittle, cracked, or compressed beyond useful tolerance.
•  A failed gasket allows oil leaks, which can lead to external oil dripping, contamination of other engine parts, or reduced oil levels.
•  Oil leaks may also allow air ingress or blow-by, which can hamper engine performance or lead to further gasket failure.
•  Leaks can cause unsightly stains, smoke (if oil contacts hot parts), and may even trigger engine warning lights or damage surrounding components.

When to replace:
•   Anytime the valve cover is removed (e.g. for camshaft work, head servicing), the gasket should generally be replaced rather than reused.
•   At the first signs of oil seepage or wetness around the valve cover edges.
•   After extended usage (especially for vehicles over 100,000 miles or many years) as part of preventative maintenance.
