How to know if you need engine repair


As long as you're good about always getting to the shop for your regularly-scheduled maintenance, you'll be doing your part to help decrease the odds of engine trouble arising in the first place. But even if you do stay current with maintenance, it can still come in handy to be familiar with common signs of engine trouble so that you can know to head to the shop when a symptom arises. Here's a look at six signs that you need engine repair.

Check Engine Light

When the light turns on, it isn't an automatic indication that you're on the verge of automotive disaster. Nonetheless, you'll still want to take the necessary precautions and have computerized diagnostics done so that you don't end up needing major engine repairs that could've been avoided.

Knocking Noise

A repetitious knocking or tapping sound could be an indication that you're seriously low on oil, with the noise itself occurring because of a lack of lubrication. By simply adding some fresh oil, the issue might be remedied. On the other hand, this symptom could turn out to mean that you need a rebuild on the bottom end of your engine.


Vibrations that emerge from your engine might also be a result of low oil, with the metal-on-metal contact being the source of the vibrating.

Worsening Gas Mileage

While various automotive issues can cause this, one possibility is a problem with your engine's compression stroke.

Loss of Power

With older vehicles, it shouldn't be too alarming if there's a bit of power loss over the course of a number of years. But if the power loss is sudden and extreme, then you'll want to visit the shop for diagnostics.

Excessive Exhaust Smoke

The color of the smoke can provide clues as to what the issue is. Black smoke suggests too much gasoline is being burned. White smoke could mean that there's a coolant leak. Smoke that is tinted blue could mean that you have an oil leak.
