4000csq valve tapping gone possible cure

["Joe Rae" <quattro@ptinet.net>]

About a week ago I was at the local Al's/shucks/pepboys parts store and was
wondering around looking at switched and air horns and stuff when I walked
by the oils department. Looking down I saw a bottle of STP oil treatment, so
I bought a bottle. It has been 3 weeks since my last oil change and the
valves on the 4000 were tapping quite loudly. So I decided what the hell, I
would sue STP if the engine blew up ;] then drop in a MC turbo engine. Well
I poured about 3/4 of the bottle ( the stuff is like slime) and half a
bottle of oil. The next morning I was a little worried to start the car up,
but cranking it up and no more tapping. It has been a full week and about
800 miles  with still no tapping.???
Has anyone else tried this because I am usually very skeptical about the
snake oil/ techron additives/oil cleaners but this seems to have stopped the
noise.
