I think my block is toast, anyone want to tell me otherwise?

tearing into my h23 that spun a bearing, I noticed something that didn't appear to be right on journal mains #3-5
here is main #1,

main #2

main #3

main #4

and two shots of main #5


those little indentions that are on the right side of all the halves except fot main #1 shouldn't be there correct? If I put new bearings in there won't they just spin again? thanks in advance

Re: I think my block is toast, anyone want to tell me otherwise?

I'm familiar with engines, but not the 4th GEN specifically, but I believe that there should be some "oiling" holes in the block and the bearings as well. And in the 2nd picture of your 5th main, it looks like those holes are plugged with bearing material. Can you snap a shot of the other bearings or at least confirm that they each have a small hole in them? Or does the oiling come from the bottom caps?

It looks as if those notches were there from the beginning and not caused by something, exept for the last one which has a part of the bearing stuck in there.

Well as you can see in the very first picture, there is no little notch on the right, only the notch for the upper bearing half that is on the left side. On main 3-5 I understand that the lower bearing half (that rests in the cap bridge) worked it's way into the block thus grooving out those little notches on the right side. I'll post a better picture of the 5th main in a little bit, but I don't think it's bearing material stuffed up in there

here are two kind of better shots
as far as I know these slots are not for oil, they are for the bearing to fit into so they have a edge to rest against on the other half. and these appeared to dig into the edge rendering the block unusable.........right?

H series are bottom feeders, meaning the oil is fed from the main caps. I would likely find another block. They are easy to come by
