Update: Still had burning oil smell. Return was still dry but there was a different source which it think is the real source. I think that on the pressure side of the rear turbo, the hose clamp was a little loose and the retainer clip that holds the clamp to the pipe kind of pulled it away from the turbo housing. I think oil would pool around the connection and when I would go into boost it would squirt it through. That said I got a little freaked out that a turbo seal was leaking but I checked all the other piping and tried to drain the CAC but there was minimal oil everywhere else. Fingers crossed, car dealers suck!! ( I also found the noise maker bracket was cracked and crappily crazy glued and gorilla glued, bunch of hacks.)
