Also do a thorough EGR tune-up on it.. including cleaning out the Delta-P sensor and piping, etc. ++ ensure the exhaust back-pressure circuit is not clogged up going thru the thermostat housing.

-=== and fix the exhaust problems hat are throwing codes while your at it.

and if your getting exhaust smoke then remove and clean out the EGr valve.. pressure test the CAC.. do a turbo inspection.. and remove the DOC and DPF.. have them de-ashed, baked, and flow tested. Take pics of their faces and post them here as well.. to show any contaminants.

These engine need a of of care and attention.. they don't fix themselves.. they cannot heal, and no repair shop is going to go thru it and do tune-up work. They also cannot keep themselves clean, especially the EGR circuits, etc. ... and it sounds to me so far like yours has been seriously neglected?.
