Checked the downpipe today. No oil there. Good news...turbo is ok. As it seems it is the oil feed that is causing problems. Changing that tomorrow.

 

Ok we have checked everything now ther is no oil in downpipe as well as no trace of oil in the intake. Turbo seems to be fine there is no foul shaft play or traces of oil where it should not be.

Compression has been checked and it is perfect. All of the cylinders lined up perfectly.

But after all of the check ups are done nothing was resolved, car is still smkoing white-blueish smoke. Usually when the gas pedal is not pressed and the car isn't moving. It does not smoke at all when the engine is cold or first started. there aren't also any problems with starting the engine.

Any suggestions?
