Oilleak near turbo
 

Drove the car for the first time today, and i noticed that besides running like shit (which turned out to be water around the plugs from cleaning the engine bay) it also had a lot of smoke comming from the turbo-exhaust.
I haven't located it exactly yet, but it seems to be comming from between the firewall and the turbo downpipe elbow.

Is this a common place for oil to leak, and would it be the oilpipe of the turbo or the headgasket spurting oil onto the exhaust?
