It's worn through the coating. There's a little divot by the oil hole also. This is the worst one. I'm going to change them out.

I had a funny knock develop in the engine in my '51 after owning the car 29 years. Oil pressure was good, but nothing I did tracked it down. I swapped in a '51 Merc I had, which required that the oil pans be swapped. When I cleaned out the Ford pan, I found a chunk of the thrust surface of the rear main in the bottom of the pan. It was about 1" long and the full width of the thrust flange. I really don't see how that caused the noise, but I am assuming that it was the cause of the knock. (I know what they say about the word "assume."

My knock happened suddenly, you would think the culprit would be obvious like yours.

make, borrow, or buy a oil pressure pot, use it to force oil into the engine, watch where it leaks more than drips, look there for something out of specifications

Sometimes when an engine sits for a while (a month or so) a piece of carbon comes loose from the combustion chamber near the valves and sticks to the top of the piston and contacts the head,which can sound like lower end noise since it forces the rod against the crank momentarily. Any chance that could be the issue?

I suppose that's possible, I was running it hard the day before. I always wanted a bore scope, now I have an excuse, might be a good time to buy one.
