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.

Fel-Pro PermaTorque Head Gaskets
Fel-Pro PermaTorque head gaskets are the industry standard for no-retorque designs available today. The torque retention is gained through premium materials comprising four distinct components--core, facing, coating, and armor--and the process used in the manufacture of the gaskets. Fel-Pro PermaTorque head gaskets have been proven to retain the highest torque retention significantly better than other brands. These composite-style gaskets compress at installation to conform to and seal minor surface imperfections, while retaining the ability to resist or recover from compression during engine operation. The result is a clamping force and a secure seal over a long period of time--without retorquing.
