nice "good ol boy" remedy there!

I would make sure to do a hot oil change and definitely no more than a 5w-30 viscosity with those temps, maybe you dont have much cheese whiz but there could be some dried up gunk inside from 9 years of previous driving with that CCV?

Best way to find out, even if you don't have the sound at startup, is to pop the oil cap off with the engine running, and see if Chewbacca returns. If its quiet, your CCV has life in it.
