Anybody knows what this could be?

Car does this for a few year's now and runs perfectly fine.

Could it be AC related? That's the only thing that never worked on the car.

 
Solved it, the PCV Valve caused this. After cleaning the noise is gone for the last 300 miles, didn´t even sound like the typical PCV Valve sound but somehow it was :smiley:
