You have to use a micrometer or vernier caliper and measure the size of each rod journal. To do this u need to be able to measure to a tenth of a thousandth of a inch (very small increments). You need them all to be very close to each other. Looking at that one bearing from cylinder #1 my guess is that rod journal is out of spec from all the metal on metal contact. If everything specs out ok, and there is a smooth surface on the journals (you shouldn't be able to feel any scratches the crank would have to be polished, or the quick way is to use crocus cloth and polish it with the crank in the car. From there you would install the new bearings and make sure to plastigauge everything and make sure the clearances are .002 or less (usually 1.5-1.7 thou is optimal clearance. Even then you still have to figure out why the bearing failed in the first place, be a bent rod, bent/damaged crank, or a faulty bearing. When u tighten down each rod end caps for the last time make sure to turn the engine over a full turn and verify everything spins nicely without binding up.
Also remember that if u spun the beaing, it can keep oil from getting to the wrist pin and cause damage up there as well to the surfaces too.
