You are correct, smoke typically suggests a long period of city driving and then you take the car on the freeway and you notice black smoke in the exhaust which is no more than the unburned particles collecting in cold weather and city driving in the exhaust system being blown out.
Alternatively, you have many bad glow plugs that are not functioning in the post start up glow.---Very strange as you dash would lite up indicating a bad glow plug.
You indicated that your injectors were cleaned and springs changed or shimmed to bring back to factory specs---that's good.
Our injector pump is only adjustable for injector release timing in relation to TDC---that is not a DIY takes special mechanical and electrical equipment to correctly change.
A last thing to concern or check is compression---you could have a couple of bad cylinders, but she starts in the cold and runs like a champ---
All I can do is list the suspects for smoke, because smoke to you may not be smoke to others and when smoke occurs and doesn't is also important-----
I would take the car to a diesel truck mechanic---they hate working on cars, but they know diesels!!
