I pulled the 2nd and 5th rod bearing cap and both had about the same level of damage. I think .010 cut would fix these. I pulled the third (from front) main cap and it is trashed.

What does the pressure relief valve look like? I'm seeing a spring loaded rod. I can seen through the end of the oil pump into the spring. I can see the rod through holes in the housing above where the gears are. I can see that the valve has the hole closed off right now.
