Must-Know Signs of Engine Trouble


By staying up-to-date on your maintenance plan, you can help to reduce the chances of major engine trouble arising. Still, even if you pamper your car, it could develop engine issues. And if it does, you'll want to be familiar with the signs so that you know to quickly get to the shop. Here's a look at six common signs that you need engine repair.

Knocking Noise

The tapping sound could arise from a lack of lubrication, suggesting that your oil has gotten dangerously low. In this scenario, you might be able to solve the issue by simply adding oil. On the other hand, this symptom could indicate that you're going to need a rebuild on the bottom end of your engine.


This could also be due to low oil, with the vibrating happening because of metal-on-metal contact.

Check Engine Light

When the check engine light illuminates, it doesn't automatically mean that an automotive disaster is just around the corner. Nonetheless, you'll still want to bring your rig to a mechanic for diagnostics so that the detected issue can be addressed and you minimize the risk of needing major repairs.

Power Loss

As a vehicle enters its golden years, it shouldn't be too worrying if it gradually loses a bit of power. But if the power loss is extreme and seemingly comes out of nowhere, then you'll want to have a mechanic take a look.

Excessive/Off-Colored Exhaust Smoke

Whenever exhaust appears to be off in color, it's worth further investigating the matter. If the smoke is black, too much fuel may be being burned. Blue smoke suggests an oil leak. White smoke could mean that coolant is leaking.

Decreasing Gas Mileage

While a variety of automotive issues can cause a drop in MPGs, one thing to consider is a problem with your engine's compression stroke.
