3 Common Causes of Major Engine Trouble


3 Common Causes of Major Engine TroubleModern automobiles are fascinating pieces of machinery. They are constantly reengineered to outperform, out maneuver and get better fuel efficiency than their predecessors. But without proper maintenance, all that engineering could be worthless. Major engine trouble and engine failure isn't an issue for most vehicles, but if your car has high mileage or isn't properly taken care of, there is a chance of ending up stuck on the side of the road with major problems. But what actually causes possible engine failure?

Detonation

Detonation is caused by ill-timed combustion inside the engine that produces mass amounts of heat and pressure in the combustion chamber. Because fuel is combusted when it should not be, excessive heat is produced, usually accompanied by a knocking noise. This is likely happening because of the failure of the exhaust gas recirculation system, which ensures a proper air/fuel mixture. However it can also be caused by bad fuel, incorrect ignition timing, wrong spark plug gaps or elevated engine operating temperature.

Improper Lubrication

Likely the most common cause of engine failure is low levels of engine oil. Even if you change the oil on a regular basis, you should routinely check the oil levels to make sure there isn't a leak or that your car isn't burning excessive oil. However, engine oil starvation can also be caused by a faulty oil pump, high mileage wear and tear, or gunky oil, which is a result of not changing the oil and/filter at the proper interval. Always conduct routine auto maintenance to ensure your car's engine remains healthy.

Overheating

If your vehicle overheats it puts it at risk of mechanical problems, such as a blown head gasket. Common causes of overheating include a coolant leak coming from the radiator or a radiator hose, or even the engine itself, if the block is cracked. The latter would result in a need for engine replacement. However other causes of overheating could include a bad thermostat, a faulty electric cooling fan, or a failed water pump. Ensure proper cooling system care by following your vehicle manufacturer's recommendation for coolant flushes. This will help detect any leaks and gives a mechanic the opportunity to inspect other parts of the vehicle's cooling system.

If you experience any signs of engine trouble you shouldn't wait to have the problem diagnosed. Issues could include lack of power, a knocking noise, increased exhaust smoke or poor fuel economy.
