You should have posted a picture of it BEFORE you bolted the main caps back on.Might as well share the bad news along with the good. The last main bearing cap (main seal cap near the flex plate) was being a total asshat and would not budge. Grabbed the trusty rubber mallet and gave it a few whacks.. On the 6th or 7th wack the 90degree corner next to the hole where the oil pump shaft passes cracked. Never in a million years did I think that would happen. That corner does not appear to have any purpose and it is not a bearing Surface. I used the Dremel to smooth out the fractured area.
Heath at Volcano Manifolds says it should'nt be an issue and I agree. There is at least a quarter inch gap between the shaft walls and the oil pump drive rod.

Now we can tell you that you should have removed the bolts before hammering on the cap.

And yes, I expect a flip-off emoji in return.
