I'll post my reply to your PM here as well so others who search will find what I did when I had the exact same problem.

Like I said, I'm pretty sure my problem is the valve seals, but I don't have the time or money to do motor work, so I poured in some Lucas Oil Stabilizer with my next oil change and the smell/smoke went away. It only just started to come back, about 3500 miles later. Time for another oil change and some more Lucas.

Typically, when a car has worn valve guides, or seal, it will puff on no load decel. If, however, the smoke runs up with the revs, then look for bad rings. But you certainly can't ruel out rings...

leakdown test will pinpoint the problem clearly, if the engine is fine, blame the turbo.
