Rebuilt Engine bearing wear

What you have is not rod knock. There’s no way a bearing will make noise if there’s oil pressure and 002 clearance. You have lifters that are bleeding down and not pumping up. Remove, disassemble, and clean the lifter check valves.
See that's what one would think. That what I thought. But it's undeniably rod knock. I have no idea how it's possible but it is. Maybe the machine shop didn't actually check the crank for roundess... but I swear they did. It's the only explanation though. All bearings are in spec.
