its probably the oil seals in the turbo i have worked on several with the same problem the turbo shaft itself may not have any play in it but the seals can still be bad. i have mine rebuilt at a local turbo shop here it costs $400 to rebuild them not bad considering the cost of a new one

but it could also be the injector orings but i'm leaning more towards the turbo.
