What happens when rod bearings go bad?
A damaged or worn-out connecting rod bearing may result in excessive rod knock, which is a rapping noise produced by the engine. This means that the clearance between the connecting rod and crankshaft has changed, hence the knocking sound.

How do I know if my rod bearings are bad?
Low Oil Pressure - Many times when a bearing is beginning to fail (or has failed), you will noticed signs of decreased oil pressure. This is usually more evident upon first starting the vehicle. In many cases, a bad rod bearing will lead to a "check engine oil" light being displayed on the dash.
Why do main bearings fail?
Most of engine bearing failures are caused by one of the two factors: - Mixed lubrication with direct metal-to-metal contact between the bearing and crankshaft surfaces; - Fatigue of the bearing material. Mixed lubrication is one of the main causes of engine bearing failures.
Why Can Bmw Rod Bearings Fail?!
Can you drive with bad engine bearings?
In essence, the car will not function properly, and if you continue to drive in such a state, further damages will occur. One symptom of a bad engine bearing is silver shavings in the engine oil. Soon, you may start noticing some awful noise from the engine due to the rod knock, and the oil pressure will reduce.
How are rod bearings diagnosed?
If your vehicle has a worn out main engine bearing or rod bearing, your car will usually display some or all of the common symptoms: Knocking Noises - If your car engine knocks upon starting the car, there is a good chance that your engine bearings are worn and need to be replaced.
