May be the turbo seal leaking,starts and runs well,does it use oil,?

[Olderisbetter]

Starts well runs great and does not seem to be using oil.

I’d temporarily disconnect the air intake at the inlet manifold and see if it makes a difference,if it does then the smoke is oil being burnt,then if it is oil reconnect inlet pipe and disconnect turbo boost pipe and try again,this should determine weather it’s the crankcase or turbo
