EGR or headgasket?

[Armour]

hey i got a 2005 powerstroke 6.0 with an intake edge juice w/attitude (peice of junk) and a 4" mbrp exhaust. what my truck had been doing was dumping HUGE amounts of black smoke on levels 0-5 didnt matter and i thought it was pretty weird.but i was at work so ruffed it out and kept driving for about a week. then a few days after i was back started it up at noon about 5 hours after it was last started it. went to go in reverse and when it got to 1200 rpm it it pretty much died out and went back to ide and idles fine and the truck started just shooting out white (coolant im guessing) and my degas bottle is pretty much empty. asked a few people they said egr. the mechanic is saying headgasket but on mylast 05 i blew mygasket by towing. anyone hurd of a headgasket going like that? eather way im planing on doing egr delete but dont want to have to do theheadstud yet (short on cash).could this guy be just saying headgasket to make a few extra buck?

I kinda doubt he is just trying to get in your pocket book. Head gaskets are a common 6.0 problem. along with egr coolers,oil coolers etc etc etc the list goes on and on.
Egr leaks usually blows coolant out the tail pipe, both can cause exhaust gases to get in the coolant. Depending on where the head gasket is damaged you can get water in the oil,or just have it going in the cylinders and then out the exhaust, this can be acompanied by excessive crank case pressures. Kinda hard to diagnose without pulling injectors and rooling it over gently to see if any coolant get blown out.
