Excessive white smoke after GP and oil change

Changed Glow plugs & relay, oil & filter, air and fuel fiters.
Truck was smoking at all before. Now it smokes white, alot.
Used Beru plus, but i dont tink its the GP's. Just doesnt make sense.
Oil is Shell Rotella T5 synthetic blend 0w40.
I soaked up the oil aroud the GP's before removing them to minimize oil running into the cylinders.

If I accidentally unplugged an injector, would it smoke like this?
Any ideas?

I think one or more glow plugs isnt getting power. I would check all the wiring.

If you unplugged an injector you would know it for sure. there would be a difference in the way it runs.

i'd start with checking that your GPR is putting out power if it is then unplug each plug to the vavle covers and ohm the gp they are the outer pins on each plug

does it clear up once the motor is warm, or is it like this?

GPR is from NAPA.
Smoke does not clear up at all. Does is when warm just the same.
And it does not run the same, seems to shake more. It ran real steady before. Its almost as to one hole was doing anything.
Yet if an injector was unplugged it shouldnt fuel that cylinder and not smoke. right?
