    Did you just install the kit? If yes, check the wires on the oil return pump. If the polarity is reversed, oil will come out of the tail pipe. I have seen oil in my intake pipes ever since I got the kit, nothing major...but it's always been there.

    Is the oil going to the throttle body causing any problems?

    Buddies lt1 sts was smoking bad out the tailpipes and it was overfilled in the crankcase.

    Interesting about the pump polarity and stuff.
    Thats one reason I like my turbo setup.no extra oil pump..feeds off filter housing and returns gravity style..nice and simple.
    And turbos seals dont' blow like that .But you can get oil out thru them if you have some problems with crankcase venting. And they can let oil out past the seals if they are worn out and really shot which guess could happen if you had some major oil starvation issues.

    I would bet money its the check valve in your oil pump.....or you could have a collapsed return line under suspension load.
