A complete lack of lubrication in the crankcase usually leads to seizure of the bearing and total failure of the engine. But experts say a more frequent issue regarding lubrication 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 number of them. 

When the bearing is damaged by oil starvation you’ll find a very shiny surface and evidence of wiping.Remember, the failure of the oil film can be seen in a variety of ways on the bearings. Check or such things as blocked oil passages, a malfunctioning oil pump, improper ina bearing selection or installation, oil seal failures, fuel dilution (often caused by blowby of fuel and air past the piston rings) or foaming or aeration, caused, ironically, by an overfilled crankshaft.

Sometimes, failures are the result of simple installation errors. For example, if a bearing half without an oil hole is improperly put into a position where the hole is needed, that journal will receive no lubrication. 

Other types of assembly errors may also be seen. If a connecting rod or main bearing cap is installed in the wrong position, or a bearing isn’t set into place securely, lubrication will be insufficient and cause failure. Careful installation procedures are, of course, critical in every aspect of engine building – careless errors are always expensive.
