oil comming out of breather? normal
#2
I'm guessing you're talking about the pcv valve outlet (tube runs from there to the air intake tract just before the throttle body), and no, it's not normal. Should be clean. You may want to try cleaning out the pcv valve with some carb cleaner, it may be stuck open (take it off and shake it, if it doesn't rattle then it's stuck); or as a long shot I suppose if your air filter is extremely dirty it could be causing a restriction which might be forcing the intake to draw excessively from the pcv valve. Just a couple of ideas; I'm sure somebody here might have better ones.

No its not the pcv I don't have a breather on the pcv. Its on the drivers side. Usually a hose runs from there to the intake before the supercharger but I put a breather onto it to clean up the engine bay.do I maybe need a catch can?

yes ^^
I would get a catch can. How much boost are you running? If it is what i think you are describing, its where your crank case vents. Does it get worse when the engine is under boost?
alot of boosted cars have this problem. It happens when the car is under boost and then you let off quickly and the pressure bleeds from the crank case out the valve cover. What you are seeing is the small amount of oil that is being blown through the breather. just get a catch can and you'll be good to go.

I'm just running 9lbs(need a boost-a-pump :/).ya, it is the crank case vent. I noticed it when I was at the track on sunday,that's when it was bad.
If I where to do a catch can how do u do it? Get a cylinder and run a hose into it and empty it every once in awhile?

Copied from MMR's site, but other vendors sell basically the same thing
96-09 2V,3V 0r 4V Valve cover Breather kit for Supercharged/Turbocharged applications
This complete kit allows you to vent the valve cover/crank case pressure to the atmosphere, This prevents your turbocharger or supercharger inlet tube from sucking oil out of the engine and burning it which causes smoking, oil leaks, Detonation and poor performance. Kit includes all lines and fittings to attach to factory valve cover. Breather tank includes filter and mounting bracket and can be mounted in any location including the fenderwell and includes easy drain fitting.
Specify year @ checkout>>
Basically mount the can to the fender/fire wall, and run the supplied hose to where you have your breather filter. Check it every couple of weeks(depending on how hard you drive the car) and empty as needed. I will be running one on my setup....
