In warm temps or cold.... it smokes.
On a warm summer day, what you get is,
no smoke for 5 seconds or so and then the smoke comes pouring out for a while and as
the engine runs for about a minute it dissipates and basically disappears as the engine warms and throttles down..
Has a slightly blue tinge to the smoke or steam....
In winter some of it, maybe a lot of it, is obviously moisture
as evidenced by the huge clouds produced in freezing temps on start up..
Cant prove it but I think a lot of it is steam.

If it has a blue tinge, it’s likely oil. The seal in the turbo could be leaking. While the engine is not running, oil seeps into the turbo. Then when you start it up, it takes a few seconds for the turbo to get hot enough to start burning the oil. That’s how it was explained to me when mine was smoking but it turned out my catch can was full.
