white smoke after injector swap and glowplugs

I recently had #3 injector faulting causing codes so I tore passenger side down to replace that injector yesterday and found both injector #3 and #1 missing the nut to the little bolt that holds spool valve assembly together and the red power wire broke at top of molded spool valve electrical part. So I swapped in 2 injectors off the spare 6.0 motor I bought for backup, engine is of course used and don't know the history about it, so really no idea about the injector condition, but they looked ok, and I put new o-rings/coppers on them. While I was in there decided to swap in 4 new motorcraft glow plugs because 3 of them(off brands) were faulted out, and unfortuanately managed to break the glow plug harness at #7 plug, oops... while putting truck back together I noticed the coolant overflow was a little low, so topped it off... the first time I tried to fire up truck the engine stopped turning over mid crank as if something was physically lodged somewhere, but the next time I cranked it, it fired right up... immediately got an unbelievable amount of white smoke out the exhaust and a weird idle sound that eventually seemed to smooth out, so I just assumed it was something to do with the used injectors having sat so long... well after about 10 minute drive and 10 minute idle time, it just smokes a little under half or more throttle now, pure white in color...

WHAT THE HECK COULD BE WRONG???

:dunno:

The stopping while cranking is hydrolocking. Now wether it is fuel or coolant is the next thing to figure out. Usually if it is fuel then while idling it will start to knock and run rougher and rougher...if the overfueling is that bad. With coolant low I would probably start there. Any smoke before the work was done?

No smoke before i did the work... a mechanic at work told me to fire it up on my next day off and smell the exhaust, whether coolant or oil smelling....he thinks the upper o ring didnt seat on one of the injectors or one of the injectors is bad and letting oil into the fuel side of the injector.... i thought only coolant produced white smoke and that oil tended to be grayish... thoughts???
