Apparently if the engine has had an easy life and not worked too hard the bores can glaze. This glazing or polishing means the bore surface is very smooth / shiny thus allowing oil to pass between the sealing ring & bore wall and into the combustion area - hence the smoke. Diesel engines like to work!, running at low revs or idling for long periods will lead to glazing as will frequent short trips where the engine will not be able to fully warm through.
The solution although it sounds brutal works. My first attempt would be to run the engine hard, under heavy load with high rpm, the engine will smoke heavily until the bores start to rough again and the oil seapage slows. The second method is even more brutal and you can pm me if the first does not work and I will explain further.

Indicators that this is the case are oil consumption and the ability to discount that it is the cooling system is to monitor the coolant level to see that the engine has not been consuming coolant.

Obviously the minced turbo internals mean something has contacted the inlet guide vanes and that should be the first concern - making sure nothing is still in the intake system.
