Knocking Noise from Engine
Listen for a knocking noise when the engine is running. This will likely be worse when the engine is cold and before the oil has had a chance to warm up and begin thoroughly lubricating the components. A rod knock is a hollow sound that speeds up as the engine RPMs rise. The knock may still be there when the car is warm or may go away entirely.
Low Oil Pressure
Check the oil pressure. A bad rod or rod bearing can also cause the oil pressure to be excessively low. Signs of low oil pressure can be an oil pressure light turning on or a low oil pressure reading if the engine has an oil pressure gauge.
Excessive Oil Consumption
Determine if the engine is using excessive oil. If the engine is consistently running low on oil, it may be due to a bad connecting rod or bad connecting rod bearing.
