I had a broken stud on my valve cover and replaced it yesterday. After doing so I am now burning oil, and I have looked under the hood and also under the car. I have found that the intake side of the turbo is leaking oil as well as the oil pan where we tapped it for the oil return ! What is a good fix for this? I know I need to reweld the oil pan but why is there oil leaking from my turbo?
