As the moving parts in a motor heat up during use, they require ample oils and lubricants to keep them functioning correctly.

An insufficient oil level is the most common cause of engine rod knock, and the damage that occurs as a result of throwing a rod is often expensive to rectify. Indeed, a lower engine rebuild is usually necessary to replace crankshafts and lower gaskets, and sometimes a complete engine rebuild is also required. If a vehicle is not particularly valuable or of sentimental value, it may require breaking if a total engine rebuild is necessary.

To prevent throwing a rod in future, be sure to maintain the correct oil and coolant levels, regularly service the vehicle, and check that the water pump, thermostat and radiator are functioning correctly.
