Valve speed?  Collapsed lifter.  Not an uncommon problem.  Change the
oil and filter, add a pint of Marvel Mystery Oil and drive it. It'll
clear up. (BTW< if you have an orange filter on it that is directly
contributing to the problem.  Replace it with the proper Mann or Mahle
filter and it will preclude its reoccurance.  (In a pinch, the Purolator
Pure One or NAPA Gold filter will work *almost* as well. See filter
study at <http://wetwesties1.tripod.com> Follow the link at the top of
the filter study page to the German filters.)
