today, i took off my intake, and i noticed some oil(?) in my supercharger. is this normal?


here is a close-up

 

Yes. There are two possible origins of oil there. The first one is small seapage from the oil jacket around the bearing - no biggie. The second is from the front breather hose from the valve cover. That hose connects to the pipe between the air filter and the blower. You can get oil vapours pushing through that line.

 

I had the exact same thing happen and ended up putting an oil catch can on the hose that xviper mentioned. its been over a week now and i have a few drops of oil inside.

you may want to look into a similar setup to minimize the amount of oil buildup you're getting.

 

I have puzzled about that also.I suspected Oil vapors from the Hose that comes in the intake from the head and there were signs of that,oil comming from the head.. but i than removed the hose put a breather filter on it and closed the hole on the Intake hose...Than few weeks back i saw little oil before the SC blades and i was worried...now when Xviper said that that's no biggie and explained where it comes from i am not worried any more...

 

I dont know about CSC style ones, but in my last car that had a roots style, oil in the supercharger could also be an indication of boost inside the engine causing blow-back. Never seen anyone mention blowback here so maybe CSC's dont suffer from that.
