What are the causes of engine failure?

Engine failure is usually a major problem and causes much damage, requiring extensive overhaul. Failure of an engine results from several issues emanating from lack of proper engine service as recommended. Here, I will explore what are the causes of engine failure that call for engine repair more often.

What are the causes of engine failure?

• Lack of Regular Maintenance:  Failing to replace the oil, among other maintenance activities, may result in severe damage to the vehicle engine. Engine oil serves as a coolant and reduces friction between moving parts in the engine to avoid getting hot quickly. In the absence of proper intervals of oil change, the oil gets contaminated and loses its efficiency, resulting in excessive use of the engine's parts. This may lead to complete failure of the engine, and in the process large amount of repair work on the engine has to be done.
• Overheating:  Another cause of engine failure is when the engine overheats. They include faulty cooling systems, low coolant levels, and a defective water pump as common causes of overheating. In the case of an overheated engine, the metal parts swell and bend and, as a result, the entire system fails. Failure to inspect the cooling system often leads to the vehicle overheating, eventually requiring the engine to be repaired.
• Timing Belt Failure:  The timing belt is essential in maintaining harmony between the camshaft and engine crankshaft. If the timing belt becomes damaged, it will stretch or break, resulting in engine stalling and many internal strains. This is a common cause of engine failure, and it is recommended that one changes the belt per the manufacturer's advice.
• Fuel System Issues:  Issues with the fuel system, like a dirty fuel filter or a faulty fuel pump, can hinder fuel from reaching the engine in time. This may lead to the inability to start the engine or the engine cutting off during operation. These problems and the necessity of engine repair can be avoided by properly caring for the fuel system.
• Ignition System Problems:  The ignition system is another vital factor that plays a large role in the starting of the engine. Inadequate spark plugs or ignition coils will also hinder the engine's operation or cause it to stall. Timely inspection of ignition system parts and replacement can go a long way in eliminating chances of engine failure.

Improper Servicing or No Services of an Engine causing it to Break

This is compounded by the fact that failure to go for a service as recommended may worsen these issues. For instance, when spark plugs are not replaced when they become bad, the engine starts to misfire and utilize more fuel. If a small coolant leak is not attended to, the engine will likely overheat and cause much expense damage. Each of these issues calls for engine repair, which can be expensive and take a long time to accomplish.
