Could be leaking into the bellhousing.

BUT, how do you know?

Always check the gearbox oil cold, sfter the car has been standing (ideally in the same, absolutely flat, position) for at least 2 hours.

Could be the turbo seal?

Depending how much is being sucked through there may not be much smoke to show for it.
