Seems to be leaking oil from here. Before this the drain line below was leaking right where the ntp fitting screws into the turbo. I took it out and reinstalled making sure it was as straight as possible to the oil pan. Then after that I reinstalled with some thread tape just to make sure. Hasn't leaked there again. Couple of weeks later and it's now leaking from here. What do you guys think? Failing gasket? Failing turbo? Or failing me?
