I wonder if the bearings could be changed out as opposed to replacing
the
entire turbo.

Yes, along with the seals. However, when you pull the compressor off the
shaft to slide the bearings off, you disturb the balance. Balance is
critical at 130k rpm. Then there is that pesky FAA thing about engine
accessories having to be overhauled at a repair facility.

Do you use Marvel Mystery Oil?

Not in this aircraft as of yet but I have used it in other non-turboed acft
in the past. Can it handle the heat of the turbo and do you think it might
help clean the bearings?
