- Inside, noting burning oil from the exhaust?
- Oil Inlet side of the turbo ?
- Oil return line of the turbo ?
If it is one of the last two, it is simple repair. The inlet line is a copper O ring that will require two wrenches remove the line itself. The return line is harder to get to (removing the AC compressor helps) and is a metal gasket, with 2 6mm allen screws holding it into place.
The job (replacing both) should take less than a couple hours!
