Stan's already been there done that.
MMO, Engine flush, New Oil Filter, 15/50 Mobil 1, adjusted the valves.
One rocker shaft lookslike it wasn't getting oiled.

Mary,
If Tom is right about your problem being lifter noise then you might
think about an oil change to 20W50 oil.  I do not know what you are
running now or how old your present oil is but an oil change would be a
cheap first step in fixing your problem.  You may also want to check out
Stan's suggestion about adding Marvel Mystery Oil before you change the
oil.  (Maybe Stan will e-mail you the procedure if he sees this.)  This
treatment will clean your lifters etc.
