What are the potential signs of major engine trouble?By being diligent about always getting to the shop for your regularly-scheduled maintenance, you'll be doing your part to minimize the chances of engine trouble arising. But even if you stay on top of your maintenance plan, it's still good to know common signs of engine trouble in case symptoms of a problem do start to show. Here's a look at six signs that it's time for engine repair.

Check Engine Light

Drivers sometimes ignore an illuminated check engine light because it doesn't always mean that a major issue is brewing. Regardless, it's best to play it safe and have computerized diagnostics performed so that emerging problems can potentially be detected and remedied before they turn into expensive nightmares.

Knocking Sound

If you're hearing a repetitive knocking noise, it could be happening because you're extremely low on oil, with the noise itself arising from of a lack of lubrication. Simply adding oil might take care of the issue, but it's also a possibility that the bottom end of your engine will need to be rebuilt.


Vibrations emerging from your engine could also be caused by low oil, with metal-on-metal contact being the source of the vibrating.

Excessive Exhaust Smoke

The smoke's color can help you determine what exactly the problem is. Black smoke could be a sign that your car is burning too much gas. White smoke is suggestive of a coolant leak. If the smoke has a blue tint, it could mean there's an an oil leak.

Decreasing Fuel-Efficiency

While this symptom could emerge because of differing problems, one possibility is there's an issue with your engine's compression stroke.

Power Loss

Gradual loss of power in older cars shouldn't be too concerning. On the other hand, if the loss of power is more sudden and significant, then you'll want to get to the shop.
