Unless they are bad out the box but how do you tell if the turbo is leaking water into the oil. I have Z1 GT535 turbos with the upgraded stainless steel oil lines I don't think you can mix them up. What I really would like to know is where else I might have mixed up a line but I don't remember any other oil lines except for the two going to the cooler.
I only had the plenum off when I had the engine out. And I don't think there are any oil and water areas there to mix up??
