03 7.3 idi turbo knocking smoking (vid)

I need help figuring out my truck. It had a knock when I got it so I replaced the injectors. It was not smoking at all except on start up.
Now its rough idling knocking and smoking pretty much constantly like this. also feels low on power. I checked coolant and it is good. also checked for cavitation. Also I know my cdr valve is bad but it wouldnt cause this much of a problem. I had a leaky return line and 2 kits later I finally have that sorted and sealed. Got reman'd injectors from pensacola diesel. Thinking one or more are bad.

Good news is i swapped some of the injectors today with some i suspected bad and it got rid of the higher ticking sound but the truck is still smoking at idle and driving almost just like in the pic. still has a nok nok nok nok type sound just not the ticking sound with it like in the vid.
