Has anyone else had this issue of the obx dp not sitting exactly flush on the turbo. I thought I had a manifold leak until I ripped all that apart and replaced the gaskets. Now it's still making that annoying exhaust leak noise. I used a oem gasket for the dp and I climbed under there today and see that it is for sure the dp. The bottom bolt is as tight as I can get it and there is still a gap between the turbo and the flange on the dp. I even tried loosening the top bolts and tightening the bottom but still a gap between the two.
