I tried finding the thread where Jake explains how to get to it with a scope from underneath....no luck.
I split the cases so I haven't actually scoped from the sump
The bore scope will usually show nothing in regard to cylinder wear. Why? Because the wear starts at the bottom of the bore. This is the point that is covered when the piston is positioned at BDC for a bore scope evaluation. The piston covers the point where wear begins, and is always the greatest.
The only way to see this is removal of the sump plate and going in from underneath, through the "back door" with the piston at TDC during inspection. This means you have to scope through the spark plug hole, and through the sump.
The issue is that you can only access 3 of 6 cylinders from the sump plate due to obstructions.
Your flywheel could have gone from "flailing around" to "locked up". If its in the locked up mode, to verify drive in 4th gear at about 1500 rpm and see if you get any "gear noise" when lugging. (will sound like an old worn out dump truck trans). Trust that the noise didn't just go away.

I'm betting the noise didn't go away either, unless it was something else entirely. Right now all signs are looking up.
