I found a lot of discussions that have info that sometimes contradicts so sorry for bringing this up again.

On the dry sump engines, what are the signs that it needs to get addressed?

-Slight rattle on startup for a second or two on cold/dry start? (I read some posts saying ALL engines do this?)
-Long/sustained/continuous noise?
-Only if you start throwing cam timing codes?

If you get noise out of dry sump it usually only last like a 1/2 second...It is not the horrible noise a wet sump makes...If you are getting variator faults then most likely the bushings are worn...4200s don't seem to have very many issues with this at all for some reason...More a QP thing...Jason

Hi Jason. So if I get a short burst of noise but no codes/other obvious issues should I be at all concerned?

No, I hear them make a little noise occasionally, but I wouldn't worry about it on a 4200...I usually only fix them on QPs and it is normally because it sets cam timing faults and they can't get their emissions ...Jason
