look. take off the inlet to the turbo. grab the shaft nut, pull it out and push it in. there should be little to NO forwards and back movement. a tiny amount is not necessarily bad but not good. side to side there should be a tiny bit. not very much but should be able to feel it. if there is a LOT of play, its toast and i would NOT run it.
Get the car warm, and shut it off and drain as fast as you can the oil, you can drain the oil and add some gasoline and run it though a coffee filter. same with the oil filter, can opener, no saws. and cut the pleats out in one but, fold into accordion and press in a vice to get oil out and inspect for metal. clean the metal with gas again and now that the bits are clean tell us if its brass or aluminum or iron. Brass means the turbo journal bearing is FUBAR should be pixy dust like, aluminum means you have damaged some lifters or bores, or bearings ect.... fairly large pixy dust or more. Iron means the cam and maybe some gears are worn down. again, larder than pixy dust here.
anything larger than say a grain of sand in size is bad. ultra fine glitter is ok but if its brass then your turbo is GONE.
