Sorry meant take off "Turbo charger" yourself not engine. ...Silly distraction.

What happens is there is often residual heat in the turbine end, and when the Engine has stopped without the Exhaust cooling down adequately, and no oil circulating to take heat away. The heat will migrate from turbine end to the bearings and raise the temperature of the oil, till the oil "cracks" leaving a tiny deposit, perhaps blocking oil passages. Would think your bearings are roller type. At minimum your bearings need to be replaced and a good clean out of the labyrinths and Turbine. I'd say subsequent damage may have been done, more so because combustion hasn't been clean so Exhaust temperatures have been elevated, possible distortion of shaft. But still worth a go. Considering the highly balanced sensitive components suggest you get specialist dismantling. But you could save a few dollars by taking off the engine yourself. Good luck.
