So, The most common cause of mechanical problems is improper engine lubrication. The lack of oil will result in excessive metal on metal contact. The cause of oil starvation is a faulty oil pump. Also, High mileage wear and tear. Of course failing to change the oil can also be the culprit.

So, Abnormal combustion will produce excess heat and pressure within the combustion chamber. This means that fuel will be combusting when it should not be. Often causing a loud knocking noise. So, The most common reason detonation occurs is the failure of the exhaust gas recirculation (EGR) system. This system is what ensures a proper air/fuel mixture.

Another big problem is overheating. If this happens it can cause several parts to fail. Overheating often occurs due a coolant leak. So, Overheating can cause blown head gaskets, cracked blocks and other problems.
