Here is an album with some pictures of the
old conrod bearings I removed not long after I bought the car. The top halves on every pair are the more worn ones. There is 1 which looks worse than the others, I don't know which bearing is from which rod unfortunately, but I feel like the bad one is from either 1 or 2.
There is a picture of all 4, and there is 2 pictures of each bearing, one top down and one from the side. Sorry about the reflection it's hard to get the light right. I don't believe I measured the clearance on these before replacing them, I just looked at them and decided they were obviously fubar so replaced them all.

I pushed a pin up through the oil holes in the rods to make sure they are not blocked, they didn't appear to be.
I was thinking if there is a flow issue, wouldn't it be affecting the bottom halve of the bearing too.... because there is just one oil supply hole in the crank on each journal, this would supply the whole bearing as it rotates?By the way, my oil pressure was good before I disassembled, 18-20psi once warm on idle ( up at 80psi nearly cold start ).
Here's a picture of the bottom of main bearing #3 ( and a close-up )
They all looked like that, same with the top halves. The top halves also have the groove for the oil, so they are in the right way at least.
