Truck has 29,990 on it. Injectors were super loud from day one. Somewhere over the past 6 months or so a new noise started. The best way I can explain it is it sounds like a midget behind the passenger firewall tapping the motor with a metal hammer. The noise takes a minute or so to occur at startup, but after that it's there all the time. While cruising down the street and then letting foot off gas the noise stays where the RPM's were, then rolls off down to idle. So it was time to take it in.
Dropped at the dealer almost three weeks ago. Took them a bit to isolate it. Misfires all over the passenger side bank. No shavings in the oil pan. At that point it became a back n forth with Ford. Dealer suspected a rod, but had to follow Ford's direction. Eventually the head was pulled. Cam is scored, I didn't get confirmation for sure, but the rod in cyl 4 went south. The dealer was approved for a short block replacement but the tech and writer are both pushing for a long block. Tech said this was the 2nd early '12 5.0 he's had this issue with.
There's a bunch of videos of 5.0's knocking. NONE of those were the noise I had.
