1. Check that you are not ingesting oil trough oil-breather.
2. Check compression and leak-down.
3. Check valve stems for wear (yes, you need to remove cam covers)
4. Check scavenging pump.
5. If everything is OK, you might have a blown turbo bearing seals or worn bearings.

Personally, I find your chances to be like this:

15% faulty scavenging/breather/whatever
25% valve stem wear
35% blown turbo
25% cracked piston compression rings
Thank you for your time,
