What happened to this bearing?
Working on an engine over haul and have gotten as far as removing the pistons. The connecting rod bearings all show some bluing.
What would cause this? I found some info that it can be caused by fuel in the oil but I know this isn't the case since I took an oil sample in for analysis prior to the rebuild. No fuel in oil reported.
Any ideas?

That looks normal at that mileage for upper shells on the rod. If it was also the bottom shells, then maybe the engine was run on too thin of oil.
