bent shit is boring, unless it's super bent. We want to see stuff that 'sploded!
I will never forget the day I pulled the heads off of a 5.8 EFI engine in an F250
that had what I'd describe as a "light knock" and found a rod with a wrist pin through it in one cylinder and not the slightest trace of the piston from that bore until I dropped the pan off the engine...
As for "taking the pan off" of a 4.0 in the chassis? Not possible.
