[QUOTE="fordpsdtech, post: 1193580, member: 16975"] Not saying this is what you have but I got one torn apart right now, customer states started making noise, running rough. Found broken rocker, replaced rocker, valve bridge, and push rod, did not see any damage to top of the lifter, put it all back together, ran great but still ticking, rechecked and found too much valve lash, inspected oil filter and found silver metal, pulled cab and head, found lifter lost its roller bearings and ate the cam. Tore apart further and found all cam bearings gritty and mains are scored along with crank, and front cover and pump are toast. I do not think that you are dealing with a fuel issue, the injectors were probably good too. Hopefully its just a rocker issue for you but I would pull and inspect that filter. [/QUOTE]
