Types of Engine Bearing Damage | KnowYourParts

A complete lack of lubriion in the crankcase usually leads to seizure of the bearing and total failure of the engine. But, experts say a more frequent issue regarding lubriion is simply inadequate oiling. The absence of a proper oil film will result in metal-to-metal contact, occasionally to just one bearing or often to a nuer of them.
