I am looking into the possibility that a large number of substandard quality
valve lifters were introduced into the supply pipeline in the late 90's. If
you have experienced lifter spalling at mid TBO or before, I would like to
talk to you. I am particularly interested in cases where there are no
obvious causes such as long periods of down time, lack of preheating in cold
weather, etc. Please reply directly and not by post.


Oils. Ask about oils. Some oils have been known to damage cams and
lifters, especially in brand L engines. That's why the maker wants you
to use an oil with the special additive in it.
