Typically, car manufacturers recommend that you service your vehicle once per year or every 12,000 miles, whichever comes first. This can be more frequent if the engine is exhibiting any signs of trouble. The truth is car engines can experience a variety of problems that require attention and repairs. Knowing what to expect can help you identify an issue with your engine before it gets worse.
Here are 10 common car engine problems and what causes them:
1. Misfiring Engine
You know an engine is misfiring when it makes an unusual sound, such as a “puttering” noise. This occurs when one or more of the engine’s spark plugs are firing incorrectly or not at all. The most common cause of a misfiring engine is faulty spark plugs and wiring, but it can also be a faulty engine control unit. According to car manufacturers replacing spark plugs every 30,000 to 100,000 miles is ideal.
2. Dirty Engine Coolant
When engine coolant becomes dirty or contaminated, it can cause overheating and other engine problems. The most common cause of this is a coolant leak from the hoses or seals in the cooling system. To prevent this issue, make sure that your vehicle’s cooling system is flushed out with fresh coolant every 24 months, or as specified by your car manufacturer.
3. Leaking Oil
Oil leaks are common in older vehicles and can lead to engine damage if left unchecked. The most common causes of oil leaks are loose bolts, cracked gaskets, or worn seals – all of which should be checked regularly and replaced as needed. Also, make sure that you change the oil in your vehicle according to the manufacturer’s recommendations. You should also check the oil levels in your car regularly to ensure that it’s not leaking from any other source.
4. Faulty Combustion Parts
Faulty or worn combustion parts, such as spark plugs, fuel injectors, and ignition coils can cause engines to misfire or run rough. It’s important to check these parts regularly for signs of wear and tear and replace them if necessary. If you’re having trouble starting your car or it’s running poorly, one of these components may be to blame.
5. Oil Starvation
If your car isn’t getting enough oil, it can cause serious damage to the engine. This is because oil lubricates the moving parts of the engine and not having enough oil can lead to excessive wear. Make sure that you’re checking your oil levels regularly and topping them off if necessary. If you find that you’re constantly having to add oil, it may be a sign of a bigger problem such as a leak or another issue.
6. No Engine Lubrication
Another common engine problem is a lack of lubrication. Without the right amount and type of oil, the moving parts of your engine can suffer from excessive wear and tear. It’s important to check your oil level regularly and to change it as recommended by the manufacturer. If you don’t have enough lubrication, it can also lead to overheating, which may cause further damage.
7. Too Little or Rich Air/Fuel Mixture
For your engine to run properly, it needs the right air/fuel mixture. If there isn’t enough fuel or too much air in the mix, then this can cause poor performance and possibly even engine stalling. This is usually caused by a faulty oxygen sensor, carburetor, or fuel injector. When these components wear out or become clogged, they can cause your engine to run inefficiently. You should have these components checked and replaced if needed to maintain optimal performance.
8. Oil Sludge Build Up
Oil sludge build-up can occur when the oil in your engine hasn’t been changed regularly. It happens when oils break down and become a viscous gel-like substance that collects on engine components like pistons, valves, and spark plugs. This can cause serious damage to your engine as it prevents proper functioning and circulation.
9. Too Much Heat in The Combustion Chamber
Heat buildup in the combustion chamber can cause excessive pressure. This can lead to problems like knocking, pinging, and poor performance. It may be caused by a faulty thermostat that doesn’t open or closes properly or a clogged coolant system. The knocking sound may start gently but will increase in intensity as the problem worsens.
10. Malfunctioning Oxygen Sensor
The oxygen sensor measures the amount of oxygen in the exhaust. A malfunctioning oxygen sensor can cause serious damage to your engine, as it causes a rich fuel mixture and leads to increased emissions. This will also cause poor drivability and fuel economy. If you notice your engine idling rough or misfiring, have your vehicle inspected for a faulty oxygen sensor.
