Ive juse got my lil tidbit of experience here.

Brad Penn, forever, and always, Break ins with Gibbs, and assembled with Gibbs engine assembly paste. LOVE this paste for cams, and coating friction parts before assembly.

Use to use the ARP assembly lube and the pan looked like a kids diaper after a hard night of pork and beans...


Never a fan of AMsOIL as i hate their sales pitches, and telling me to run oils to 20000 miles and change filter to 10K

THOSE WORDS SHOULD NEVER COME OUT OF A SALESMANS MOUTH!

But I have never seen any kind of dirty sludge in the pans of any engine Ive built after I stopped using the Moley paste...
