mine did that. Had no shaft play. Now its got no play at all... It seized. Although it wouldnt even make 0 vacuum when it was making that noise

Every time you do something with the turbo.. you should prime it. When you replaced it, you drained the oil.. So theres a chance you could have fried it, or are frying it. Be more specific with chainsaw noise.. I don't understand it. Coming from the cabin, under the hood, I dunno.. be more specific.

The noise sounds like it's coming from under the hood, or possibly from the exhaust. I'm not sure how else to describe it...other than it sounds like a chainsaw

It's not high-pitched, as I would imagine grinding turbine blades would sound.

And I forgot to mention, I primed the turbo before I started everything up. Disconnected the CAS and the injectors and cranked it for a few seconds.

Also, I didn't point this out explicitly, but the turbo boosts fine. Pretty damn hard, actually...
