Thread: Fresh BBC; Noisy Valvetrain

Tweet

you need more than 500 on a big block to need long slots if you looking for answer ? on your lifters you could have some junk in the lifter like denny said .about putting one new lifter in that hole yes you could do it if the lifter is not wipe out the face of the old lifter looks good you could try a new lifter i would say you have 50/50 chance and it may not work. i would take the new lifter and sand the face a bit with wetdry 600 grit paper with WD40 and see if it takes. sanding it will help the new lifter brake in use moly on the face of it make sure it turns free in the bore oil only on the body not moly .the moly should only be on the face of the lifter

I pulled the lifters on the "noisy side" of the engine last night including the #8 intake which I found to be "the ticker" and all of the lifters are rock solid when I push on them on the bench. None of them exhibit any unusual or excessive wear on the bottom end and all of my cam lobes (upon preliminary inspection) look good. On the lobes, there is a little trail along each one that gets slightly wider as is goes over the nose. This, to me, is normal. I will measure for lift tonight.
Most of the lifters have a barely noticeable, almost like a "rasberry" (for those who've had smallpox vacc), wear pattern. That, to me, is also normal. The rest of them are hard to determine...nothing unusual though.

I'll sand the new one before I install. Anything else I should look for now that I have it apart and based on what I have described?

Side note: can you re-use intake gaskets?
