WTF is this THING in our 340 ?!?!?!?

Well that was a quick easy answer. We had a butterfly pin from a Kinsler stack get sucked in. Took us a while to figure out why that cylinder was running hot. We figured it got puked out on to the track. Not so, it wound up in the intake screen for the dry sump. still can't figure out how it made it there.
