Ouch...whatever that is looks like it gouged the cylinder wall as well.

What square drive is this? Not 1/4 or 3/8.
I think you forgot a picture?
I hear you, but I would want to see the cylinder so I can ponder solutions while I walk away. Stopping there might assume the worst, then again, some people might get so mad they ruin what's left before they find out the real issue. I don't think that's you though Wade.
If it was never ran with whatever that is in there maybe the cylinder is okay the rest of the way down? A fella could turn it over and gouge it the whole way down.
I have an 8mm square drive in my toolbox, no idea why I bought it but I must have needed it for something. 5/16 or 8mm would be between 1/4 and 3/8

I have a set of square drives @6 or 7, including the 1/2 3/8 and 1/4
You are correct. Plugs in the oil filter adapter. 5/16 square hole. Ground a 3/8" driver down.
Frustration is one of the triggers for my TGA. And heat differences. Heated shop into snow. There are 2 of my triggers. Good thing I got a decent night's sleep.
Looks like ring. I see witness mark in the picture, but can't tell how bad it is.
Seeing blue towl wipe marks in lifter valley had me suspicious yesterday. Some had looked at it and put back together. The intake gaskets looked new too.

If you can't get that stuff out and the oil pan is coming off the easiest solution is to pull that piston to remove the debris so no more damage is done. Might be salvagable, don't know until we see it. Was definitely ran that way because the debris dinged up the piston top and embedded itself in the piston, you'll likely see similar but much smaller marks in the harder iron head.
Correct on all counts.
It's obviously been rotated some to pressurize each cylinder, plus before that:
Engine is upside-down now. Stopped for lunch. More to come later.
I also think it looks like either someone dropped something in there, or it looks like it could be the separator piece that goes between the oil rings. But for the oil ring separator to be above the compression rings something major had to happen, like a damaged cylinder wall. Hopefully that's not the case.
Yes it was.
I ran it back down and the scar is not noticeable and the fingernail test did not catch.
That's unfortunate. Your LQ9 or L86 are looking like more attractive options now...
This is what fell out when I tapped on the piston.
It did not get to the rings.
Minor tapping on the head.
Cylinder. I can not feel the mark and a razor blade does not skip going across it..
I think it is part of a star washer. I don't think the engine ran with it in there. My guess is that it fell in there before I got it. The damage you see is from compression testing the engine.

Looks like you could get away with running it as is, depending on if you wanted to ball hone it with a drill and put fresh rings in it or not. Cyl;inder wear looks minimal, you can still see the crosshatch pattern.
Its hard to tell in the pictures, but it looks like its been there for a while? It doesn't look fresh to me, but either way it doesn't matter, if you can't feel it with your fingernail I wouldn't be too worried about it too much. It may not seal perfectly but it shouldn't be a showstopper.
However, why was the oil 4 quarts over full with antifreeze? Still need to figure that out....

Well that’s good news
i would file down that bump in the piston and buff the sharp edges smooth and run it .
but there is the ck5 way ......... pop up pistons / stroker crank / big cam / aftermarket heads / blower or turbo ........
