What makes this Fel-Pro valve cover gasket set better for repairs?

The set is engineered for the realities of repair work—sealing surfaces are not always perfect, so the material and design prioritize conformity and durability. Components are real-world tested on vehicles to ensure they perform under typical driving conditions.

• Proprietary cork-rubber formulation offers flexibility and compression recovery
• High conformability helps seal warped or uneven valve cover flanges
• Includes all necessary gaskets and parts for a standard valve cover replacement
• On-vehicle validation reduces risk of premature failures after installation

How should I prepare and install this gasket set for best results?

Thorough cleaning and inspection of the valve cover and cylinder head sealing surfaces are essential before installation. Replace any damaged hardware and follow torque specifications to avoid over-compression and to ensure a long-lasting seal.

• Clean sealing surfaces of old gasket material, oil, and debris
• Inspect valve cover and head for warping or cracks—replace if needed
• Use recommended torque sequence and values on the valve cover bolts
• Replace mounting hardware if worn; use the included parts from the kit

How durable is the gasket material under normal driving conditions?

Fel-Pro’s cork-rubber compound is selected to resist compression set and to remain resilient across typical temperature cycles in engine bays. While durable, longevity depends on installation quality and operating environment.

• Formulation resists oil soak and deformation for consistent sealing
• Designed to handle standard engine heat cycles and vibration
• Performance validated through on-vehicle testing for real-world durability
• Proper installation and maintenance extend service life
