had my injectors checked by the dealer and they couldn't find anything wrong with them

 

Keep an eye on the oil level. If you notice that every time you check it the level gets higher your injectors are bad.

Next thing, are you using coolant?

Only other white smoke complaint can be from lack of compression. If you can't find a fault in the injectors and rail pressure is not below spec, then I would say your next step would be to have a compression test and leak down test performed. This will not be a cheap test, as the injectors will have to be pulled to perform these tests.

 

Remove the Edge and see if it helps.

 

Updates??

 

I don't know what it takes to be promoted up from "newbie" but all other suggestions are very similar to mine (without quoting). Check for axial play in/on turbo shaft, oil being blown into engine if turbo shaft seal is leaking, blowing into engine, it is a fairly easy repair.
You can run it if turbo is leaking, until axial play eventually causes turbo to hit housing, breaking 'blades' apart, injecting metal into your engine. A bad injector could put a hole in your piston if malfunctioning as well. Get 'er done ... NOT WISE FOR THE 'OL MAN TO IGNORE!

 

Reckon the next test on the list is a compression test.

 

there was a bad injector in my buddys 04 cummins he drove it for a two weeks and lost #5 cylinder head

 

Updates??
