The oil return line fell off somehow (I think that's what it is, it's on the bottom of the turbo and connects to the intake manifold), and I had to take off the turbo to put it back on (if there is an easier way, someone please tell me). Well, now that it's all back together I have an exhaust leak where the wastegate connects to the dp. I wouldn't imagine so because it doesn't go to the o2 sensor, but does this have any negative effects? Thanks.
