Outside the box or am I off the wall, Lol.
If this area in not high stress or pressure maybe something such as this?
Green = Block
Red = Plug
Black = Spring Steel Shim (.003", .005"?) rolled to fit in bore
Silver = Old Bearing Shell
Blue = Epoxy Filler? JB Weld?

Nope, you are thinking correct. There is very little load on a main bearing IN THE BLOCK. The load is IN THE CAP. Like I said, the leak would be so small as to be insignificant. There is very little stress there.

You can turn a simple fix into a nightmare by using fillers, sleeves and all the like. If you were going to run the snot of of it, maybe, MAYBE, I'd sleeve it.

I never understand how guys make something out of nothing. This is NOT as rare an occurrence as you might think. I've seen it several times. They are still going.

To the OP...don't sweat it. File down the sharp edges and let it go. Or you will end up redoing the main line. Changing from stock to ARP bolts won't require a line hone. Changing to studs will.
