Causes, in order of what I would personally troubleshoot:

1) PCV valves (Remove oil fill cap, put your palm over it. excessive pressure can mean bad PCV valves and/or bad rings)
2) Valve stem seals (Will only smoke when cold/startup)
3) Piston rings (Dry vs. wet Compression, leakdown test. Leakdown through the oil fill cap means worn rings)
4) Turbo seals (No way to troubleshoot on car, pull the engine)
