My question is...... How do the other 6 rod bearings look?
If they're fine, then it's obviously not an oil pan/supply issue.
Fwiw, .0025 on the mains for that type of build is tighter than I would have let go.
I would have made them .0035-.0045, preferably with coated bearings.
.0025-.0030 on the rods, again coated bearings.
I have used several sets of Eagle 7.100 rods with the arp2000 bolt upgrade.
They all needed to be touched up on the hone before I felt they were ready to use.
It seemed like they were fine with the TQ settings for std bolts, but the added TQ of the 2000 bolts pulled them a little out of round.
The other rod bearings and mains are all perfect. So we are looking at stuff like that, but since that is toastm might never know, We also looking at the swinging pick-up. We are going to a static one on the next oil pan.
