I have the same thing, there was a large cloud about the size of the car, but having changed the glow plugs to all the longer length Beru ones and fitting an oil catch tank, I now only get a tiny puff, sometimes nothing. I have no leaky injectors so I'm now thinking it might be the fact it's used for lots of town driving and the last mile is driven fairly easily so the turbo isn't shut down to hot. Maybe it's just clearing out the remnants of whatever settles overnight, in which case I'd rather it was kicked out.
Try searching Rutland motors oil catch tank on here and get one fitted, easy job.i admit the smoke is a but annoying, but maybe better out than in. Just let us know if you get it cured.
