2011 F350 6.7: hmm, well we had the EGR off and then dropped a nut in exhaust manifold (trying to weld nuts on to those ones that break). ANYWAY, yeah stupidity move for me but in the course of looking for the nut with an inspection camera, found this mystery ring at a valve.
Absolutely no idea what this is. Doesn't look like anything that fell off a part or a tool. Amazingly my buddy somehow got a flexible magnet down there with the inspection camera, and almost had it. So, despite being so shiny, it's ferrous as we saw the magnet pick it up.
Bottom line, we still haven't located the nut but the mystery ring is....mysterious. 99.999% chance we're pulling the turbo and exhaust manifold now. Only question is if we wanna pull the cab to do it.
