Fel-Pro Timing Cover Gaskets
The chain of command between a crankshaft, camshaft, and engine valves is central to your vehicle's basic movement—which is why it's so important to protect the timing belt.

They're offered in hundreds of single or multi-piece sets for OE-style fitment on a wide variety of cars, trucks, vans, and SUVs; gaskets for industrial use are also available.

Cometic MLS Head Gaskets
Cometic MLS head gaskets are constructed from multiple layers of stainless steel for strength and contain load-controlled embossments that conform load distribution across the sealing area. This creates an exceptional seal by requiring less clamp load—resulting in less bore distortion. The stainless steel outer layers utilize FKM (Viton®) rubber coating, a high-temperature and chemical-resistant polymer. A topcoat of PTFE aids in resistance to fret and increased cold sealing. MLS head gaskets are available for most aftermarket cylinder heads; as with all of Cometic's MLS head gaskets, no sealants or re-torque is required.

Fel-Pro Differential Cover Gaskets
Vehicles manufactured after 1990 often have differential housings sealed with RTV silicone. Over time, extreme vehicle vibration and even rough roads can cause the RTV bead to break. If the bead breaks and the vehicle loses the axle lube, the transmission gears begin to rub and wear. That's the whining sound that you hear. Unfortunately, it's a repair that needs immediate attention. Fel-Pro offers precut differential replacement gaskets for these applications, so you won't have to worry about applying RTV and waiting for it to set up to seal. These gaskets are available in a variety of materials, thicknesses, and configurations for precise fitment on nearly 70 differential case designs. Order the model recommended for your application—and eliminate the need for messy RTV sealant.

Fel-Pro PermaTorque MLS Head Gaskets
Fel-Pro PermaTorque MLS head gaskets provide the robust seal needed to contain peak combustion pressures and temperatures—and to withstand the significant casting motion encountered in many of today's automotive engines. The gaskets feature multiple layers of steel, precisely engineered sealing beads, and advanced polymer coatings to maintain a proper contact pressure between the cylinder head and block. Unlike other multi-layer steel head gaskets, PermaTorque MLS seals also include a proprietary blue aftermarket coating that accommodates a wider range of surface finishes. These gaskets are manufactured using precision tooling to ensure exact sealing bead location and profile. Order the model recommended for your specific vehicle and engine application.

Fel-Pro PermaDryPlus Valve Cover Gaskets
Fel-Pro's PermaDryPlus valve cover gaskets feature precision edge-molded silicone rubber, which resists high heat and delivers reliable sealing on irregular surfaces. This silicone rubber is wrapped around a rigid carrier that adds strength to the gasket to resist being sucked in under high vacuum or blown out when under pressure. At the same time, it also prevents over-tightening of the mounting bolts. Note, however, that these gaskets are not intended for race applications.

Fel-Pro Valve Stem Seals
Fel-Pro valve stem seals are available in a variety of sizes, styles, and materials. These small components perform a valuable role—controlling the lubrication of the valve stems as they slide in the valve guide. Too little oil causes stem and guide wear; too much increases oil consumption and can cause a buildup of carbon. This can lead to valve seat damage and early valve grind. Order the replacement set recommended for your vehicle and engine application.
