Stopped at the Ford Dealership the other day because I heard a 6.7 was being torn down and of course I was curious as to why. Turns out the owner was up on vacation from GA and heard what sounded like a miss with his truck, brought it in and it has one visibly cracked EX valve (like a 2mm gap) and 2 more on the pass head that are cracked slightly. Just wondering if anyone else has heard of this? Im hoping its just one of those few trucks that happens to break down and it does not become a trend with others. I think it had like 20k on it or something close to that.
