I am trying to find the source of the white smoke at idle that is worse on acceleration on my 1991.5 ve Cummins I have ball honed the cylinders, replaced the piston rings, replaced the head gasket, new cylinder head with new valves, seats, springs, arp headstuds, oil pump, water pump, new radiator, thermostat, intercooler, starter, air filter, hx 35 turbo, hvlp, fuel filter, Oregon fuel injection stock rebuild injection pump, ddp 5x12 injectors and have checked piston protrusion, correct thickness head gasket, injection pump is on tooth e, and I have rotated the injection pump every way within the slots for adjustment, have deleted the wif sensor, and fuel heater all with no change to the smoke, and now the truck has started a recent hard hot restart needing to be cranked several times while flooring the throttle truck has 290,000 miles and has no visible fuel leaks, have bled air out of the lines extensively, cracked open each injector with a noticeable miss sound without clearing up the smoke on each injector

 

Fuel smells strongly of diesel burns your eyes, have tried temporarily running a clear line from fresh bucket of diesel to hvlp inlet, and another clear line to the return line with lots of bubbles coming out of the return line. Also noticed lots of black specs in the fresh bucket of diesel when I was done with this test, and while doing this all rubber lines were bypassed also I have removed the fss plunger it was completely hole with no missing chunks, and replaced with a brass tipped one

 

White smoke is often a retarded timing issue. Have you checked that the Key way is still present? I see you skipped a tooth, are you sure you skipped it to be more advanced?
Does it clear up when the truck is warm?

 

tooth e is the correct tooth so not advanced, the keyway is in there, and it clears up some when warm but still hazes, and smokes more white on acceleration

 

Do you have another set of injectors you could throw in it? To rule that out.

 

I have replaced my original injectors with ddp 5x12 but later learned that they are the incorrect spray pattern for my intercooled pistons, I had my original set rebuilt, but the pop pressure was set at 280 bar and I could not start the truck without starting fluid, I sent them back and had them lowered to 255 bar and had 2 leaking, I overtorqued them they still leaked I swapped them with 2 that weren’t leaking and it started leaking on these so I’m saying that I’m having bad luck with my original injector rebuilder. I have ordered a set of ducky 5x12 vco 145 spray angle and am waiting to get them, but after seeing black specs in my test bucket of fuel I’m not sure I should try injectors until I figure out what’s causing the black specs, and I’m wondering if it is a bad injection pump rebuild that I got
