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.

Auto repair shops can be divided into several categories, such as:

• Independently owned and operated – Generally, an independently owned and operated auto repair shop offers complete auto repairs and maintenance services for various types of vehicles.  They can also achieve certification to perform work on specific types of vehicles through manufacturer-sponsored programs, such as hybrid vehicles.

• Specialty shop – Specialty shops deal in only a certain component or system, such as brakes, mufflers and exhaust, transmissions, tires, electrical, air conditioners, glass repairs and installation, wheel alignment, or specific brands of vehicles. There are also shops that specialize in vehicle modifications and customization.  This type of shop may have a facility in various locations for specific jobs or vehicles, and technicians and mechanics with varying certifications.
• Auto parts store – These stores sell automotive parts to the general public, and some may also maintain a service center.

• Online auto repair shop – These online shops provide doorstep repair services and home delivery of new and used auto parts, generally not widely available in the market.

The National Institute for Automotive Service Excellence (ASE)

The ASE is a professional, non-profit organization that certifies auto repair technicians and auto repair shops in the U.S. and Canada.  It was created in 1972 in response to consumers needing to distinguish between incompetent and competent auto repair technicians.  The organization aims to improve the quality of vehicle repair and service through the testing and certification of repair and service professionals.

Some people spend months planning their summer trips. Car problems can be a real hassle, not to mention expensive! Don’t spend your precious vacation time and money in an auto shop.

Of course, that unexpected flat tire or break-down could still happen, but with the help of your auto shop, you can be as prepared as possible. Check out:

• Tires – check air pressure, tread, and look for bulges or bald spots. Under-inflation lowers fuel efficiency and increases the risk of tire damage. Uneven wear indicates a need for a wheel alignment. You may need to purchase new tires before your trip.
• Hoses and belts – These are critical to the proper functioning of the electrical system, air conditioning, power steering, and cooling system. They can become cracked, brittle, frayed, loose, or show other signs of excessive wear.
• Filters and fluids – These include the motor oil, the power steering, brake, and transmission. Check the antifreeze/coolant mixture, as well as the windshield washer solvent.
• Lights (interior and exterior) – If needed, your auto shop can replace any burned-out bulbs.
• Windshield and wiper blades – Replace wipers as necessary for those summer rain storms. Don’t drive with a cracked windshield—it will only get worse!
• Brakes -- Make sure you stop in good time when you step on the pedal.
• Battery -- The battery connection should be clean, tight and corrosion-free.
• Tune up – A pre-trip tune up will help the engine deliver the best balance of power and fuel economy.

Reduce the chance of unplanned, costly car trouble by having any necessary maintenance or auto repair performed at your trusted auto shop before hitting the road.

Radiator Service Facts About Antifreeze.

With winter's freezing temperatures here in full force, it is important that you have taken care of a needed radiator service to check the antifreeze/coolant mixture. It used to be that no matter which brand of antifreeze you chose, the color was always green. The antifreeze was mixed with water (50/50), and poured into the radiator. As the engine operated, the antifreeze performed its primary duties of carrying heat to the radiator, preventing freezing and protecting against corrosion in the cooling system. The antifreeze was simply changed at the prescribed radiator service interval. Most drivers know that ignoring this important service could lead to a costly radiator repair!

Unfortunately, many vehicle owners are confused as to what color of antifreeze is best. Because today there are numerous types of antifreeze technology which come in a rainbow of colors, be sure to get professional assistance from a radiator repair specialist. Most radiator service technicians agree that it is best to use the same type of coolant originally used in your car or truck (the vehicle manufacturer's recommendations).

Regular Radiator Service is Key!

As with anything automotive, proper maintenance is the key to longevity. The generally recommended replacement interval for antifreeze/coolant is every three years or 36,000 miles. Your owner's manual will indicate what the manufacturer recommends for your vehicle.

More important than the type of antifreeze you use is how the cooling system's freeze point protection and coolant level is maintained. Almost all coolants work best at the ideal freeze point mixture, which generally is a 50/50 antifreeze-to-water mixture. At this level, antifreeze protects to -34°F and boil-over protection to 257°F. In addition, maintaining proper freeze point protection ensures corrosion inhibitors are present at intended levels.

A cooling system that is constantly low on coolant can create an extremely corrosive environment due to the aggressive nature of the vapors of a glycol/water mix. These steam vapors are more corrosive than either fluid by itself. To check your coolant system's capacity, refer to your vehicle's owner's manual or ask your radiator repair technician.

The water you use to mix the antifreeze is critical. It is best to use distilled water, not tap or filtered, when refilling any cooling system. Tap water contains minerals such as magnesium and calcium that can form deposits in a cooling system, especially on the engine's hottest parts. Premixed coolants are mixed at the factory with distilled water.
