Scot shipped the super charger back today.... This is what he had to say: No issues. I am hoping they drained the oil before they shipped it because it was pretty much empty. There was some oil residue on the inlet and outlet. This could be a sign the seals are fading or it could be from PCV or elsewhere. I would check the oil level every 6 months or so to monitor consumption. If it goes through a bit it's not a big deal as long as you keep it topped off. I'll throw in an extra bottle of oil Otherwise it was one of the healthiest superchargers I have seen. The clutch had less wear than most, the lobes were beautiful and everything else looked and spun very nice.
