Setup and Installation Considerations
Proper installation of a cylinder head gasket is critical for engine performance and longevity. While specific installation steps vary by vehicle, general considerations include:
- Surface Preparation: Ensure all mating surfaces on the engine block and cylinder head are thoroughly cleaned and free of old gasket material, debris, oil, or coolant.
- Surface Finish: The gasket's proprietary NextGen coating technology is designed to accommodate surface finishes as rough as 80 Ra, providing a reliable seal even on less-than-perfect surfaces.
- Gasket Placement: Carefully position the gasket, ensuring correct alignment with all bolt holes and passages.
- Torque Specifications: Always follow the vehicle manufacturer's specific torque specifications and tightening sequence for cylinder head bolts. Incorrect torque can lead to gasket failure.

Operating Principles and Performance
Once installed, the Fel-Pro 26680 PT gasket functions as a critical seal between the engine block and cylinder head, containing combustion pressures, coolant, and oil. Its design features ensure optimal performance under demanding engine conditions:
- Unique Combustion Seal: Features exclusive LaserWeld™ stopper layer technology. This technology significantly reduces the risk of gasket damage from blow-out, ensuring a stronger and more reliable combustion seal.
- Multi-Layered Steel Construction: Constructed with multiple layers of stainless steel. This robust construction helps maintain consistent sealing stress across the gasket surface and can accommodate head lift, contributing to long-term durability.

Maintenance and Longevity
Cylinder head gaskets are designed for long-term sealing and typically do not require routine maintenance once installed correctly. Their lifespan is dependent on proper installation, engine operating conditions, and the overall health of the engine. Fel-Pro gaskets are built with materials and technologies aimed at maximizing durability and preventing common failure modes such as blow-outs and leaks, even under high-temperature conditions.
Troubleshooting and Common Issues Addressed
This gasket is designed to prevent common issues associated with cylinder head sealing. If engine problems related to head gasket integrity arise, consider the following:
- Coolant Leaks: The advanced sealing materials are formulated to prevent coolant from escaping the engine's cooling passages.
- Oil Leaks: Designed to contain engine oil within its designated passages, preventing external leaks or mixing with coolant.
- Combustion Gas Leaks (Blow-out): The exclusive LaserWeld™ stopper layer technology is specifically engineered to resist the high pressures of combustion, significantly reducing the risk of gasket blow-out and ensuring a strong combustion seal.
- Sealing on Imperfect Surfaces: The NextGen coating technology allows for effective sealing even on cylinder head or block surfaces that are not perfectly smooth, reducing the need for extensive machining in some repair scenarios.
Should any of these issues persist after installation, it is recommended to consult a qualified automotive technician to diagnose the root cause, as other engine components may be involved.
