Subject:      Hydraulic valve lifter (mis)operation

David:  Thanks for the explanation.  I was loosely following the discussion
and now, thanks to your explanation, understand the problem.  My lifters
seem to be working correctly thank God.  It seems obvious to me that
adjusting the lifter until it is fully extended is not the optimum solution.
  Hopefully someone will tell us how to fix it right.
