My Turbo was leaking as well. After 20k K's
It looked like this.
Took it to the dealer and they said:
"Inspected the vehicle for oil leak, turbo is not the cause of the leak, due to the location of the rocker cover breather in the intake tube - small amounts of oil vapour escape the rocker cover under boost conditions and vent into the intake tube right in front of the turbo this is normal operation washed down oil - all okay"
Others have said it is ok as well. Seems some leak and some don't.
Still under warranty so if it breaks, they can repair it for free.
