What is the most common cause of engine failure?

The most common cause of engine failure is a lack of lubrication, often due to low or dirty oil. Without proper lubrication, engine parts can overheat and wear out rapidly, leading to severe damage. Here are other common causes of engine failure:

1. Overheating: This can result from a malfunctioning cooling system, such as a broken water pump, radiator, or thermostat.
2. Detonation: Also known as engine knocking, detonation can cause significant damage over time. It occurs when fuel burns unevenly or prematurely.
3. Lack of Maintenance: Neglecting regular maintenance, such as oil changes, filter replacements, and checkups, can lead to different engine issues.
4. Fuel Problems: Contaminated or incorrect fuel can cause engine damage or failure.
5. Timing Belt or Chain Failure: If the timing belt or chain breaks or slips, it can cause the engine’s internal parts to collide, resulting in catastrophic damage.
6. Cooling System Failures: Problems with the cooling system, such as leaks, clogged passages, or a failing water pump, can lead to overheating and engine failure.

Regular maintenance and prompt attention to any problems can help prevent engine failure and prolong the life of an engine.

What Can Cause a “Service Engine Soon” Light to Come On?

Regular engine service is the best way to make sure your vehicle provides you with reliable transportation as long as you want it to.  If you think you are starting to experience engine issues, the “Service Engine Soon” light illuminating on the instrument panel could be the first warning sign.  Unless your car doesn’t run at all, head to your auto repair shop and ask for a diagnostic test.  Your auto mechanic will plug a small computer underneath the dashboard to “read” what is happening under the hood.  Potential issues can be diagnosed while they are small problems before they turn into a major engine repair.  

If you’re wondering what can cause a “service engine soon” light to come on, there are few reasons. It could be an easy fix or something more serious is happening under the hood.

1. A Loose or Faulty Gas Cap – If the gas cap is loose, fuel vapors leak out and can throw the complete fuel system off, reducing gas mileage and increasing toxic emissions.  Replacing the gas cap may take care of the issue.
2. Faulty Oxygen Sensor – The oxygen sensor monitors the unburned oxygen from the exhaust, and how much fuel is burned.  If the sensor is faulty, it cannot provide the right data to the computer, thereby reducing gas mileage and increasing toxic emissions. 
3. Failing Catalytic Convertor – The catalytic convertor reduces exhaust gases by converting carbon monoxide and other harmful materials into harmless emissions. If it fails, your gas mileage decreases, and your car won’t accelerate when you step on the gas pedal. 
4. Mass Airflow Sensor is Faulty – The mass airflow sensor tells the car's computer to add the proper amount of fuel based on the air going through to the engine.  If it fails, toxic emissions will increase, the vehicle may also start to stall, and gas mileage will poor. 
5. Dirty Spark Plugs and Wires – The spark plug seals the combustion chamber and provides a gap for a spark to jump across and initiates combustion in your engine.  If they are going bad, they will misfire.  They simply want to be replaced.

Now, do you understand what is “key” to a well-running engine?  To put it simply—take care of all service items as recommended by the manufacturer, thus helping prevent a major and costly engine repair.

Do you Know What Does an Engine Rebuild Consist of?

Most vehicle owners have heard of an engine rebuild but not many really know what does an engine rebuild consist of and why it is compulsory. There are two main reasons for an engine rebuild:  

• Worn engine bearings -- The moving parts of the engine are mounted on bearings lubricated by the engine oil so that they move freely.  When the bearings become worn, they produce loud knocking sounds and can ultimately cause failure of the engine.  The bearings are actually built to last thousands of mines, but wear is accelerated when a vehicle is not maintained correctly and is run on low levels of oil or even dirty oil.  
• Poorly-sealed piston rings -- Piston rings to seal in the expanding gasses created by the burning of gasoline within the engine. As piston rings wear, they no longer seal the cylinders correctly, resulting in a phenomenon called "blow-by.”  Blow-by occurs when crankcase oil escapes past worn rings and is burned with the fuel mixture in the cylinder. This may be the reason that older engines have an unnecessary amount of smoke in the exhaust.

What does an engine rebuild consist of?  First, the "short block" or lower half of the engine is removed, disassembled, and then cleaned so that the condition of the block can be correctly assessed. Depending on the condition of the external parts of the engine, the piston rings, bearings and occasionally the pistons themselves are replaced. The internal surfaces of the cylinders are also reconditioned to ensure that the new piston rings can form a correct seal with the cylinder walls. The cylinder head may also be renovated at a similar time.

Do you understand the benefits of an engine rebuild? First, you know that everything has been closely checked and now has new parts. Second, the worn parts are recycled to help reduce the amount of scrap in the environment.  The third, and the best, the benefit is the connectivity and compatibility with the existing ECU and electrical system.
