Moved thread to 6.0 problems section.

and it sounds like you've got issues. EGR cooler could be cracked causing your coolant to boil over. Quite possibly head gaskets blown too. If you've got a bad EGR cooler replace the oil cooler at the same time. It probably plugged and that's what took out the EGR.

Plus a few other odds and ends...

I just got new head gaskets, cyclinder heads, H11 Head Studs, Bulletproof EGR cooler, New oem oil cooler, de gas bottle, Cap, STC fitting, Turbo updated tube, fuel spring, banjos, and a powermax turbo. I still smell coolant now and then. I have a looney wild tune. My temps stay within 4-8 degrees (EOT/ECT) after the truck is at operating temp. Even if i hammer on it after its warmed up. As the truck is warming up some times it might be 20 degrees difference if i dont let it warm up to 100 degrees before driving. But once its at about 188-190 it really never varies more than 6-8 degrees. any ideas? I dont see like a leaky hose or drips. Ive heard of sometimes a tune making a truck puke coolant, could this be that? the truck never gets over 220 even up 10-12% grade at wot for 2-3 miles.
