I think I am SCREWED




I think the old Hays or Chilton's manuals used to have a section of what to look for for different types of damage.
IIRC;
Thin metallic flakes, usually not magnetic were bearings.
Black pieces of magnetic metal were cracked rings.
Very fine metal shavings/filings (Magnetic) were oil pump.

Doing the leakdown will be a little bit more difficult as you will need an air compressor, and also will need to make sure you are on the compression stroke for each cylinder you are testing. So it is a little bit more involved.
Make sure that the inspection camera you are buying will fit down into the spark plug hole. Most of the cheaper ones you can buy, have a head that is too large to move around. And buying a good borescope is a bit pricey, especially if just using it once.
If that was a piece of carbon that somehow made it into that area, it would not be magnetic at all

Good luck.

Oh and to the OP, I don't think it is a ring, I think the black chunk is from the threads on the oil filter housing and shavings/flecks maybe some bearing wear. Leak down/compression tests will tell you much more though. Keep us posted.

I looked up some threads about it but didn't find much info on the actual paint process. How long would I have to wait between coats, and final drying time? I just want to give the engine bay another reason to make me admire it for hours and keep it clean. I am removing the hood insulation and plastic vent thingy as well.
