I'm gonna go out on a limb here and say you know a lil bit about the ford diesels, see i'm lookin at trading in my f150 for a bigger truck for working purposes and was wondering about the diesel engines. I know in the 03 and up 6.0's have all the problems or is it just the earlier models? and what about the 6.4's? reason i'm asking is cuz its kinda hard to find a nice 7.3L with fairly low mileage. I guess the point here is should i look at some 6.0L's? or avoid them all together?
