New Turbo Sound...with scraping?

[jim_87]

I have been reading about compressor surge, and I am positive, that it is happening to my turbo during moderate acceleration. Mixed in with the "flutter" sound is a slight metallic scraping noise:icon_exclaim:. Could the surge be causing the turbine to be off center and scraping the housing? I have checked the oil this week and it is fine, just dirty, time for a oil change. I also did the tailpipe "finger sweep" and it is sooty, but dry, and no oil present. I plan on checking the turbine shaft play asap. Any thought, or tips?

Thanks.

Check the shaft and oil again when you change it for shavings or Debris.
