PCV system could definitely cause some smoking but I'd do a compression test first as Erik suggested. Smoking blueish white under acceleration is usually rings or turbo seals. Compression will test the first. Test while engine is hot which means removing plugs first when cold and reinstalling before warming up the engine, to ensure they'll come out when hot....without stripping.
For turbo seals, you can check the intake hose after the turbo to see how much oil is in there. Also test the turbo bearing/seal by grabbing the turbine wheel and seeing how much ply there is up and down. A bad seal/bearing may also show some signs of the wheel touching the housing..
If both of those check out fine, then it could be your PCV, but you should probably upgrade that too
