Sometimes the smoke is white, others its black.
Had 4 of my injectors come out like that after putting in new heads from Ford. Turned out that head was cracked, and the injector cups were leaking. Pressure test the coolant system with the injectors out.
I'm literally just getting it back on the road tomorrow !!
Mine was smoking black and white also. Idling weird and that's when I decided to pull the injectors.
