Great info Fish, but you didn't answer my question. :B
Is there the possibility that Ford issued this bulletin as a CYA attempt of a weak spot in the 6.7L engine? I'm not trying to be a smart a$$; I just find it odd that no other manufacturer has done this if it truly is that big of an issue. :?
Hoo, boy! Didn't even think about that! Great observation! I sure hope you're wrong!
