Paging all Garret Turbo owners-- sound from turbo at startup????
OK so I have a ball bearing Garrett GT3071. When I start the car after it's sat for a while, I hear a sort of grinding whirring for about 1 second after the car starts. I am pretty damn sure it comes from the turbo. Is that the sound of the bearings spinning before fresh, sweet, juicy oil reaches the CHRA?
Do you all hear this sound too? I don't remember hearing it for the first 15K of the turbo's life. I heard it before my engine build and now. It doesn't burn oil, it spools happily, shaft play seemed to be what it should be etc.
