Oil leak 535d from turbo
 

Hi guys,

I have a really big problem , I found yesterday day that I have a oil leak from the small turbo fin , its just leaking from there down to the large turbo to the engine tampons ... I dont have a huge oil consumption aroud 500 mil for 7000 km or so. But it just make me wonder from where it is , today we had remove the bouth turbos, and I send them for check, at first seeing the small turbo seems the have a little radian clearence , the big turbo however is w/o any noticiable clearence maybe a little radian but its really hard to notice it. I even have a video of the small turbo. So far I have changed my CCV filter with a vortex type one , and then I chenged my vacumm pump, however when I remove the CCV pipe that goes into the airfilter pipe I see there oil ... and also there is oil into the intercooler pipe? Is it possible that whole leaking to be from my CCV system? that cause extra pressure and push up oil that goes to the small turbo leak from the fin and goes down .. ? I really dont know what to do cause I have fully rebuild bouth turbos before 25 000 km ..., the car have no power loss , no smoke(smoke a little black when push to floor , cause the car is remapped w/o dpf and cat). Can you please help me ? Thx in advance!
