Must-Know Signs of Potential Engine Failure


Must-Know Signs of Potential Engine FailureAs long as you keep up with your scheduled maintenance plan, you'll be going a long way toward reducing the odds of engine problems arising in the first place. But even if you are good about maintenance, trouble could begin to brew---and when it does, you'll want to be familiar with the signs so that you know to get to the shop. Here's a look at six common signs of major engine trouble.

Knocking Sound

A repetitive tapping noise suggests that you're dangerously low on oil, with the sound arising from a lack of lubrication. While it's possible that you can resolve the issue by simply adding oil, there's also a chance that you'll need a rebuild on the bottom end of your engine.


The vibrating could also be caused by low oil, which arises from metal-on-metal contact.

Loss of Power

In older vehicles, it shouldn't be too concerning if a bit of power is gradually lost. But if the power loss is sudden and drastic, then you'll want to have a mechanic take a look.

Excessive/Off-Colored Exhaust Smoke

Anytime that exhaust smoke seems off-colored, you'll want to further investigate. Black smoke suggests that too much fuel is being burned. If the smoke is blue, there could be an oil leak. A coolant leak could result in white smoke.

Check Engine Light

An illuminated check engine light doesn't automatically mean major trouble. Nonetheless, it'll be best to get to the shop for diagnostics so that you don't risk ending up with expensive repairs that could've been nipped in the bud.

Worsening Gas Mileage

Many different automotive issues can cause a reduction in fuel-efficiency, with one possibility being an issue with your engine's compression stroke.
