Need good mecahnic for head gaskets, studs and a few other improvements on this 6.0! Any suggestions for good mechanic in south louisiana? Of course i'll call dealer, but they'll want my first born to along with payment!! LOL! had my first small puking from the bottle this weekend, nothing major, just a few white spurts on bottle, truck never got hot. I had a new coolant bottle put on about 3 months ago and will change the cap again just to be sure. 213,400 miles on it, so know it close.
