335XI turbo inlet hose oil leak

Uzi_335xi · 08-05-2013, 11:23 AM

So my car started smoking at stop lights once a week for the last month. Yesterday I noticed drips of oil under my car. After further inspection, there is oil around the turbo inlet hose which appears to be dripping down.

BMW Thornhill dealer just put new turbo's and all gaskets into the car about 2 months ago.

option 1, cold side of the turbo is shot, option 2, PCV is acting up, option 3, this car just likes to mess with my head lol

Any suggestions on what could be wrong here?

Most likely your rear turbo inlet pipe isn't seated correctly. This is fairly common actually. The oil condenses from the crankcase through the check valve connected to that pipe.

Take it back to the dealer and let them know before you start messing with it.

But what is causing the oil to get there? Inlet hose sealed or not, why is there oil going into my turbo inlet?

I told you. Oil vapors that condense from the crankcase, move through the check valve, and get dumped into that pipe.
