Bearing nock, or turbo......

[Obsession]

So all know by now that i might have a bearing knock, and that the Turbo on my car is packing up(Screams like a banshee, and only starts boosting(OKAY puffing..)) from 5000rpm. Well yesterday I ripped some of the plumbing out turbo side as I saw allot of oil in the boost pipes, and lo and behold, my dearist turbo has not got any play on it, oooo no, it travels…From here to cairo, I am talking of almost a centimetre or more of play on the shaft….

Now the car is going in tomorrow for the rebuilt, and I was wondering, could the noise witch I think is bearings(witch only starts from about 3000rpm, underload, and one can hear at 2000rpm, when u do not load the moter(IE, I rev to about 2400rpm, and slightly raise my foot of the throttle)) actualy come from the turbo itself?????

Or am I thinking like a year old hippie on some realy good sh!t???

mine did it at 4500 rpm then with time went lower and lower to 2000rpm
then i pulled the motor
