It seems more a gas outlet, but this is clearly seen in Bombardier BD-700-1A10 Global 6000 in starboard engine before takeoff

Maybe its just condensation in a particularly low pressure zone? Think of the vortices in front of a C-17 when its reversing.

I think what you are perhaps seeing (and talking about) is an oil system vent. These tend to smoke a little on many jet engines.

I couldn't see anything coming from the starboard engine.
