Valve stem seals control the lubrication of the valve stem as it slides in the valve guide. Too little oil causes stem and guide wear. Too much oil increases oil consumption and can cause a buildup of carbon, leading to valve seat damage and an early valve
grind. Faulty valve stem seals increase oil consumption.

Valve stem seal
Different than other seals in the engine, valve stem seals play an important role in lubrication. Valve stem seals allow a controlled amount of oil to lubricate the valve stem as it moves in the valve guide. The amount of oil that passes by the valve stem seal must be precisely controlled. Too little oil causes stem and guide wear; too much oil causes carbon buildup leading to valve seat damage, decrease in volumetric efficiency, increased emissions, catalytic converter degradation and excessive oil consumption.

Material Choice
Valve stem seals are made from a variety of materials, including nylon, PTFE rubber, steel, and synthetic rubber. Sometimes these materials are combined into a single sophisticated design.
When synthetic rubber is used, there are three basic types: nitrile, polyacrylate, and Viton. The biggest difference between the three types of synthetic rubber seals is their heat resistance. A synthetic rubber seal with insufficient heat resistance will harden and crack prematurely. This can lead to seal degradation, with pieces of the seal breaking away and clogging the oiling system and oil pickup screen, causing engine damage from loss of lubrication. Because of this, many valve stem seals for late
model cars are made of Viton and NBR.
