Maybe it is that the first bearings to be starved of oil are the # 2s, since
they are closest to the pump. If the pump sucks and pumps air, it would show
up at the closest bearings. Joe(B)

It seems that when the crank fails, it does so through fatigue, at the
undercut radius at the rear main. This I understand.
It seems that when a rod fails, it is mostly #2 and / or #3.
What puzzles me about this is that I would think it would be #1, but that
seldom happens. Why would I think this?
The oil from the pump / filter is piped to the main gallery immediately
behind the distributor bushing. The bushing bore and the main gallery
intersect, and the oil pump drive shaft bushing partly blocks the flow to
main #1. I would think that #1 would have the least flow.
I guess there are some things we mere mortals just aren't meant to understand.
