When they did the headstuds, were the heads sent out to be magnafluxed for cracks, flatness, and pressure tested? Did you install a new oil cooler? How about a new EGR cooler or do a EGR cooler delete?

What he said. Sounds like you have blow by coming from your heads and it's flash boiling your coolant and over pressurizing it causing it to come out.

thats exactly whats wrong with it,whoever did his heads didnt deck em!!!!! dang i hate when a mechanic does that,ITS VERY IMPORTANT to CHECK the HEADS and the connecting rods,see if they have stretched or what not,also if and when you get your heads redun,make dam sure they check the arp headstuds,I.E mesure them.

i work on these things and ive seen horrid things done to the 6.0.if you get your truck "bulletproofed" it should not blow any coolant anywere,if it does,it wasnt done correctly....
