Today driving my 1600 tp bus it last all power then locked up, stripped the engine and found that only one big end ran a bearing. The bearing pushed out on the sidesWhy would the happen and could over heating have caused it. What would go first if it did over heat. Thanks in advance as it is really bugging me.Could overheating cause this without damaging the piston and barrels.
Normally when this happens you will hear it progress, starts with light clicking to then knocking, it doesn't just seize at the drop of a coin, you missed the warning sounds. The loss of power is the last sign, this is when the rod / crank is melting the bearing.

For what it's worth, ignorance has no limits ......

If it was from overheating alone, the oil would have a burnt carbon smell and you would have damage to more then one bearing surface.
