Hi I bought an 05 F-250 6.0 about 5 months ago. I drove one week and the head gaskets let go. I found a guy local to do the job. when we talked before I brought him my truck he was very knowlegable on the problems with the 6.0 and what caused them. I brought my truck to him to get it studed, egr delete, 6.4 banjo bolts and blue regulator spring. When I dropped it off he told me he had a 3 to 5 day turn around, more like a 3 to 5 month turn around. It was almost five months he had my truck and dropped it off to me last wednesday. Needless to say the truck is not right and it was a fight for five months just to get my truck back. The worst part about it was that I lost my job in the mean time and could not afford to bring it to another shop. In tearing down the engine I head cracked heads so I got new heads not reman heads. He did the studs, gaskets, egr delete, blue spring and 6.4 banjo bolts. took truck for test drive after he dropped truck off and split and was very disappointed. Truck has no pickup and very slugish. When I put the pedal to the floor the truck goes into safe mode and will not down shift or go over 2200 rpms and the wrench light comes on. The mpg display says the truck is only getting 5.0 mpgs and that is horrible. It also sounds like something is hitting the fire wall at times under the hood and makes what sounds like a metal against metal sound at times also. When I put the truck in reverse and turn the wheel to the right it sounds like the exhaust has come undone under the hood. Needless to say I have problems and any help would be great. Oh and I almost forgot sometimes when I take off The truck doesn't want to shift out of first and when it does that if it shifts it does the same thing in second too. Sorry for the long write up but I think that is all the problems that I am having.
