7 Must-Know Signs of Serious Engine Trouble

7 Must-Know Signs of Serious Engine Trouble

With engine issues, the important thing is that you take action as soon as you notice a sign of trouble. By being proactive, you can hopefully avoid the problem worsening to the extent that major damage occurs and you have to spend a ton of money on repairs or even replacement. By knowing common signs of engine trouble, you'll be alerted to address the issue as soon as it becomes apparent. Here are seven symptoms of a serious engine problem.

Knocking/Tapping Sound

When extremely low oil causes insufficient lubrication, repetitive knocking noises may arise. Adding more oil might take care of this issue. However, there's also a possibility that the bottom end of your engine will need rebuilding.


Vibrations could emerge from your engine if a dangerously low oil level is causing metal-on-metal contact.

Burning Smell

Moving engine parts are liable to fail when burning oil leads to inadequate lubrication.

Power Loss

If you drive an older car that has high mileage, you don't necessarily need to worry if it's slowly lost some power over the years. But if it loses power suddenly and sharply, then you could be dealing with serious engine trouble, such as worn-out pistons causing low compression.

Check Engine Light Illuminates

When your check engine light comes on, it's not necessarily an indication that your engine is about to fail. Still, it's smart to soon get to the shop for computerized diagnostics so that any developing issues can hopefully be nipped in the bud.


Overheating is often the result of leaks in the cooling system. Another possible source of overheating is a malfunctioning water pump. It's important to keep your cooling system in great shape so that you don't risk overheating causing major engine problems.

Discolored Exhaust Smoke

The color of the smoke can give you a sense of what the problem is. Blue-tinged smoke is a sign of an oil leak. White smoke suggests that coolant is leaking. Black smoke is an indication of an oil leak.
