I currently drive an 04 dodge hemi 4x4 and it has been a great truck. 69,000 miles The only problem was when I broke the pcv valve in the intake. It was a bugger to get out. If the hemi starts burning oil, change pcv valve. Oh, some of them have a tick to them...Don't worry though..Mine has ticked since I bought it, most of them do. It was the way the Hemi was made. It has something to do with the angle of the push rods. The only thing that I can say is a common problem on these trucks is the transfer case seals and power steering hoses. Almost everyone I've seen leaks.
