Still trying to figure out why I have this leak on the turbo. Have had it for last 40k miles. Always slightly dirty when I change oil It isn't the return line. Rather, it is leaking what appears to be the air intake side. When I take the turbo to intercooler pipe off, I also have oil coated on the interior of the hose on the charged air output side. This seems like a common condition.

Many people say this is just the dirty PCV going into the air intake. I wonder if my turbo seals are worn?

Oil leak on bottom of turbo

 

That is common on all turbo cars.

At the dealer they were having us remove the hose. Then take a bicycle tube and cut a peice off of it and install it on the turbo then install the plastic hose and it would help alot.

 

Thanks. I'll try the "build your own seal" trick :-) I'll take a look to see how much has to come out. The engine bay of this cars always look worse than the job really is.
