Is the smoke coming from the tailpipe, or just where you indicate on the picture?

First, check the turbo for external oil leaks.

If that's not it, then pull the downpipe and check the turbine housing for evidence of oil leaks.

It sounds like the turbine seal may be leaking.

Have at rebuilt because at the same time they will balance it. But it may be cheaper to find a good used unit.

I had a bit of smoke coming from the turbo and it turned out to be a small external oil leak burning on the hot exhaust. I would check all the fittings first up.
