..............and a true story
Years ago, a small HVAC/R outfit I worked for had a V6 S-10 "shop truck." It used some oil, but we kept at it. The boss's daughter had the truck for a couple of weeks..........and seized the engine.
The boss wanted me to tear it down
So on the bench is the block, the crank, the bearings, the caps..............AND NO OIL SEAL
The thing had never had a seal from the factory!!! Absolutely no wear on the crank, nor any sign of anything in the seal groove!!!
