Dan, While in the end the bearings were destroyed, I’m not convinced you could blame the bearings for failing. If the two rods failed side by side without obvious signs of installation error, it’s more likely there was oil starvation leading to ultimate failure. I don’t think we will really ever know unless the buyer of the car tears it down and proves or disproves the theory that the Upstream main failure caused oil starvation.
Edit- take note that the other inspected BE bearings on the engine showed basically no wear in 28k miles.
