Big End Engine Problem - Diagnose,Repair Worn Conrod Bearings

Big End engine problem - WORN OUT. Pre maturely worn out bearings can be the result of dirty or diluted engine oil. When unsure and a cause must be established, take a sample of the used oil from the engine in a clean glass container and have it analysed. The result of the oil analysis will give definite answers to the cause of the failure.

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.
