Causes of Connecting Rod Bearing Failure

Connecting rod bearing failure can be caused by a number of factors, including:

• Insufficient lubrication: The connecting rod bearings need to be properly lubricated to prevent metal-on-metal contact. If the oil level is low or the oil is dirty, the bearings can become damaged.

Connecting rod bearing failure can lead to catastrophic engine damage. The connecting rod can break, which can then damage the piston, cylinder wall, and other engine components. This can result in a very expensive repair bill or even a totaled vehicle.
