Want to hear from lifter spalling victims

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.
