Have noticed a rather massive oil leak only while the truck is running. Parked it in the driveway warming up the other day and left a large amount of oil in the driveway. Here's what I know. It only leaks when running. It is coming from the passenger side. looks to be around the turbo. I have included two pictures. The steady stream of oil winds up dripping to the ground off of of the wastegate, following the trail of oil up it is all over the oil return line of the turbo. Any ideas where I need to be looking to fix this leak? maybe a gasket? I figured aybe someone else here has had the same problem. I snapped two pictures of the oil leak area when I had the air intake off looking for the leak.

 

I'd powerwash the area and see where it starts leaking from. Could be the gasket between turbo and drain tube. I had the bolts that hold the drain tube to turbo come loose.

 

make sure there isnt a crack in the drain tube itself. Look close where the flange and the tube meet up.

 

Find anything?
