If you have an overly noisy lifter (rocker), adjust it. No chemical is going to quiet it down. Go through an adjust the valve lash on all of them. Keep in mind that a little noise is good. A little loose is better than too tight.

ok, 2nd question is.. whast with the guys in the movies listening to engines with a stethescope?

Yah J Z, I just put my ear to the end of a long screwdriver. Stethescopes are just for guys with too much money (doctors?).

[jszarecki]

well, what are you guys listening for?

It makes it easier to find bad bearings.

I have a mehcanic's stethoscope and I doubt if anyone would ever accuse me of having too much money. They are invaluable when it comes to listening to fuel injectors. You can hear the sound of them opening and closing, or if they're not. Also, with a stethoscope, rather than a screwdriver, you can discern weak vs. normal sounds like a clogged injector which won't sound as loud as a properly operating injector.
