Where are you located. Members here may know of an actual diesel shop to repair the problem. It sounds like the shop your going to does not know how to diagnose a problem.
Now what I suggest you do is get, scan for codes, do an injector buzz test, cylinder contribution test. All this should have been done already.
White, greyish colored smoke usually means the engine is running cold or running lean. So I would lead to an injector or possibly high pressure oil pump problem. What are the IPR readings. I had the levels that they are supposed to be but I deleted that pm. Also this color smoke is a sign of fuel starvation. Your fuel supply pump may not be working properly so you would need to check that for pressure and flow. The fuel pick up tube could be clogged. In the tank is two fuel filter screens they can get clogged up, and then cause the truck to starve for fuel. What is the gauge reading for the fuel tank level.
I would deffinately contact one of the techs on here. Scuffy, Jon, Dirk, there are more but it is so hard to remember all there names. These guys will point you in the right direction.
As I think of more things I will add to this.
