Agreed. I had r/r'd all of the air cleaner assembly and all of the couplers connected to the turbo. Everything should be tight. I think it is more of a mechanical noise, definitely on pass side. I thought I had a bad alternator (which I had just replaced two months ago) so I swapped that out- again- but not the problem.
I have not seen too many postings about having to replace turbo bearings, but maybe it's time. Thanks.
