Oil on impeller side 
I have a 2001 camaro ss with a v9 vortech supercharger on and I have been having a oil leak somewere, there is oil on the impellar side when I check there is also oil through the whole air intake and through the maf and like I said on the impellar side and through the after cooler into the throttle body. I just sent the supercharger to ge rebuilt and they said they changed the 2 seals in the supercharger after being reistalled it's doing the same thing can the leak be coming from the upper part of the motor? any insight would be greatly appreciated...... 
Well what kind of air filter you running? If it is a K&N wash it and just oil it very lightly. I never ran that PVC system like they had it I blocked it off right away and the MAF is before the PVC system is why I mentioned the air filter as that is all that is before the inlet of the S/C. Probably a combination air filter getting your MAF and PVC getting the rest of your system. If you don't want to move the PVC you can put a catch can inline and drain it regularly. GOod luck I ran mine a long time with out any real issues.

Verdad Gallardo It could be, but not on the MAF that is gonig to have to be the Air filter or somthing comming in before it. I never had any shaft seal leaks on either one of mine I had two, but it could be, but you have to eliminate a list of things before you can make that call. Cause the PVC system will suck in a lot of oil if it is installed like Vortech's instructions show. Once he determines he has all of the possilble oil entry points isolated he can make that call and possibly send the unit back again for repairs etc...

There is also oil leaking down the front part of the motor, I cannot locate the leak, like i said previously I sent the blower back to vortech and they put new seals and bearing in it. The balancer pulley was loose so I put a new balancer bolt in and torque to spec, the front of the radiator is dry, seems like oil is flinging up under the aftercooler and the maf and throttle body and seems to drip down under on the driver side almost under the alternator, also oil seems to be by the oil filter with small drips there, I changed the oil feed line and drain line also. When I look in from the top or from under the car with it running I cannot see any oil leaking then I close the hood and take it for a ride and look again and there is oil on the lower sway bar on the driver side. Then I go back to that other problem with the oil in the implellar and intake system also. What do you guys think???
I believe it is two different problems. I think your oil supply or return line might be leaking externally or when your balancer came loose you may have messed up the seal and is continueing to leak oil and sling it around which is probably the case. Did you pin the crank or have it keyed if you had the motor gone through? If not it would be one of the first thhings I do before you mess up the snout of your crank and the balancer.

I think you are right it is two problems the first with the pvc system and the second with the balancer or timeing gaskets. Were can I get a catch can inline and check valve I guess i will start there.
