I would be looking at poor oil supply from the the front main bearing, that's the path of flow to the front rod bearing, NO. 1 rod.

So either the oil passage is blocked/restricted, or the bearing outer edge is to close to the crank fillet restricting the oil flow leaving the bearing, or the bearing crush was insufficient.

Many guys does not measure bearing crush, it is what holds the bearing in the rod.

Now you need a full engine rebuild.
