What are signs of serious engine trouble?By staying current with your maintenance schedule, you can help to reduce the risk of major engine problems emerging. But even if you consistently keep up with maintenance, it's possible that engine issues could still arise. And when they do, you'll want to be familiar with the symptoms so that you know to get to the shop for diagnostics at the first sign of a problem. Here's a look at six signs of major engine trouble.

Knocking Noise

If your engine is insufficiently lubricated due to extremely low oil, then a repetitive knocking sound could emerge. It's possible that you can resolve this issue by just adding fresh oil. But with this symptom, there's also a chance that the bottom end of your engine will need to be rebuilt.


Dangerously low oil could cause metal-on-metal contact that leads to vibrating.

Burning Smell

When oil burns up, there might not be an adequate amount to keep the engine properly lubricated.

Worsening Fuel-Efficiency

A variety of car problems can lead to a reduction in gas mileage, with one possible cause being a compression stroke issue.

Discolored/Excessive Exhaust Smoke

Whenever exhaust smoke is off in color, it's best to further investigate. White smoke is a sign of leaking coolant. Black smoke suggests that an excessive amount of fuel is burning up. Blue-tinted smoke means there could be an oil leak.

Power Loss

There's isn't necessarily cause for concern if an older vehicle with high miles gradually loses a small amount of power. But if the power loss is sudden and steep, then you'll want to bring your vehicle to the shop for diagnostics.
