Of all of the forces that act on the valves to create maintenance problems, perhaps heat is the most destructive. Heat, generated in the cylinder, is conducted to the heads of the valves, and in addition, hot gas flowing at high velocity across them, combine to make valve corrosion and distortion an ever-present likelihood. For these reasons, it is necessary that all maintenance involving the valves, valve seats, and valve guides, be carried out with the utmost care.
