I have a 99 Integra GS-R. I noticed oil on the bottom of my supercharger. It may have come from the nose. It is hard to see a trail but it accumulated by the casing where the nose section bolts up to the rest of the charger. Has this happened to anyone should I be concerned. I've read that the blowers come overfilled and will leak out. This is the second time I have seen this. First time was a year after I got the charger and now which is 2.5 yrs later. If it was overfilled wouldn't have drained out the overfill by now? What should I do?
