Default Well, don't that figure

My supercharger has been making a bit of noise, checked the coupler, that'* good. Thought, well, I could pull it again and rebuild it, but that'* a major pain dealing with 2 gaskets and getting them to seal. So I'm listening again today and I can hear it a lot when I rev it and the RPMs fall back down. Hmm, sounds like gear clash to me. So I pull the oil plug, ya, I see the oil so it'* not low, wait, that looks odd. Looks darker then it should. So I suck it all out.

Ya, that don't look good at all.

Do I really need to tell you which is the new oil, and which came out of the snout?

Guess I'm looking for another rotor pack. I just finished rebuilding and porting a supercharger. I'm not ripping that apart for the rotor, even if it'* perfect. If I still have it after my meet, ya, I'll pull the rotors and swap mine out. If anyone has a spare set in really good shape, let me know.

Mines pretty noisy to... Coupler looked fine last time I had it apart, and it'* got fresh oil. I need to figure out what it'* problem is.

I'm kind of thinking the needle bearings. I'll have to order a new set.

I saw a rotor pack on ebay for around 20 bucks. Search - M90 or Eaton m90.
