the bushings are out of your turbo. you should still get -some- boost though? sure there isnt any blow rubber connectors or anything. but if your turbo is no longer spinning as fast as it should be your #'s will be WAY down. time for a rebuild or an upgrade.

if the fan spins the shaft isnt broken. is there excessive shaft play.

Seal gone. You should rebuild or replace the turbo and have a look in the intake horn to see how much oil it's been injesting - just for shyts 'n grins. Maybe need to flush the intercooler.
