wait wait wait are you saying a piston rod, is knocking? I have worked on many of these engines and have never seen that have seen many and I say many with cam and lifter issues normally lifter will stick causing it to score the cam and and then its normally a easy cam and lifter job but, if it is a piston rod knocking they don't just start knocking. how often do you change you oil change and do you use synthetic or coventional

No had the lifter problem before this is a rod. Oil changed every 3 to 5k at dealer never actually asked whether they used synthetic or conventional. They did say this was rare but after several major issues in front end, transmission, and engine I'm pretty much done with this truck

That s@cks big time! From what they cost new you would hope it would last longer than that!
