Common Symptoms of an Engine Problem


It's important to get your car to the shop when you first notice a sign of engine trouble. If you ignore the issue, you run the risk of it worsening to the point that you need increasingly expensive repairs. At Hye-Tech Auto, our local mechanics are experts at diagnosing and repairing engine problems. Don't hesitate to give us a call if you notice any of the following symptoms of engine trouble.

The Check Engine Light Flashes On

When your check engine light illuminates, it doesn't necessarily indicate that your engine is on the cusp of disaster. Nonetheless, it's smart to visit the shop for computerized diagnostics so that the issue can be identified and addressed before it escalates. Oftentimes, check engine lights get triggered by faulty catalytic converters, oxygen sensors, and mass airflow sensors.

Warning Signs of Engine Trouble

It's important to investigate any strange sounds that come from your engine. A knocking noise can arise due to a variety of issues. Bad rod bearings can cause a knocking sound. A lean air/fuel mixture can also cause this symptom. If you're driving with dangerously low oil, then you might hear a tapping noise that emerges due to a lack of lubrication. This could make your engine's moving parts susceptible to major damage from metal-on-metal contact.

Power loss is another sign of engine trouble. If you drive an old car that has a ton of miles, it's not necessarily a red flag if it's lost a little power as the years have passed. But a sudden loss of a lot of power could mean you're dealing with a serious engine problem such as worn-out pistons.

You'll also want to keep an eye out for discolored exhaust smoke. The color of the smoke can give you clues as to the underlying issue. Black smoke suggests that too much fuel is burning up. Blue-tinted smoke is a sign of an oil leak. If you're noticing white smoke, then there could be an internal coolant leak. White smoke could mean that you have a blown head gasket.
