Normally the turbo will turn with very light pressure. The one on my sister's 740 gas turbo would spin freely, but the ones on the diesels wont' spin much if you flip the wheel.

My Volvo didn't spin at all when the turbo finally died -- you could turn it fairly easily, but it didn't spin if you flipped the wheel with a finger tip, and it definitely had a couple binding spots in rotation. No boost at all, and VERY low power...

worth having it check out, for sure.
