Engine Valve Cover Gasket
This gasket forms a critical seal between the valve cover and cylinder head to prevent oil leaks and protect internal engine components from contamination. Made from high-grade rubber or elastomer materials, it’s engineered to withstand high heat and pressure. In classic engines, cork gaskets may be used, requiring extra care during installation to avoid over-compression.

Common Valve Cover Gasket Failure Symptoms:

• Age: Gasket hardens and cracks, leading to oil seepage
• Physical damage: Over-tightening bolts can crush or deform the gasket
• Chemical damage: Incompatible sealants may degrade the gasket material
• Obvious leaks: Oil may visibly seep down the engine from the gasket joint
• Mysterious leaks: Oil residue may appear in unexpected areas due to engine bay airflow
• Air intake issues: Severe leaks can cause vacuum leaks, misfires, or check engine lights
• Burning oil smell: Oil leaking onto hot exhaust components can emit a distinct odor
