When corrosion occurs after the in-process time, the cause may be a corrosive atmosphere. Heat treat departments may exhaust corrosive fumes. One of the most corrosive is sulfur dioxide fumes which will quickly corrode metal surfaces.
Chrome prevents the stem from galling when cast iron guides are used, and it helps prevent positive valve seal wear on intake valves. If the chrome is ground off and the valve stem is not replated, it must be used with either a bronze liner or guide.nadequate lubrication may be caused by oil starvation in the upper valve train due to low oil pressure, obstructed oil passages, push rods, etc. Lack of oil can cause stem scuffing, rapid stem and guide wear, possible valve sticking and ultimately valve failure due to poor seating and overheating.
