Help: Engine Knock w/ Greyish White Smoke

I have an early 99 its makin a knocking noise with a constant flow of white smoke with a really destinctive smell to it. Its not burning any oil i have heard so many different things would like to ge it narrowed down I was in cruise control when it happened the truck is running a bully dog power pup 4" straight pipe its also a 6 speed its not the turbo already had it off and checked. Has 220000 miles and 35" w/ 6" lift thats all the mods!

Any help would be greatful b/c I am boggled.

Also loss of power and sounds to have a slight miss! When cranking over it seems to hit then crank hit then crank but it will start up and when u first start it it wont knock or smoke then after about 30 sec or so it starts knockin and smokin!

And what is that smell that is so distinctive? Antifreeze burning? Seems like the only things can possibly make their way into the exhaust pipe from your motor are gonna be either diesel, oil or water. Those are about your only options. Checked your water level? I believe there are seals at the base of the injectors that when they leak allow water to get into the cylinder. Maybe thats a place to investigate. I'm sure someone else will chime in here.

Well got'em pulled out today they dont look to bad they are going to need o rings of course none of the o rings were broke but a few are a lil chewed (the bottom o ring closest to the nozzle) ... I also noticed when I pulled the I believe on the number 7 cylinder where the knock was coming from the bottom of the injector looked like it was stuck open where all the others were closed so I sat it to the side but when I looked at a few minutes later it closed up so I am thinkin it was the one dumping all the fuel.

Everything seems to be running fine but!

I switched out injectors from AB to AD and the truck starts right up and idles fine but it is dead it feels like something is holding it back there is no smoke or noises the temp and oil pressure are good but the exhaust temp feels a little warmer than usual.

Could it be the HPOP or fuel pump I dont know I boggled I read that the AD's should do fine and I have heard u need to change a few things.
