What are warning signs of engine trouble?

When you first notice a symptom of engine trouble, you'll want to be proactive about taking care of it. This will give you the best chance of addressing the problem before it badly worsens and requires repairs that are much more expensive. Here are seven warning signs of engine trouble.

Loss of Power

If you drive an older vehicle that has gradually lost a small amount of power, then you don't necessarily need to be concerned. However, if your vehicle has abruptly lost a lot of power, then there could be a serious problem, such as worn-out pistons.

Knocking Noise

An extremely low oil level can lead to inadequate lubrication, which may consequently result in a repetitive knocking sound. It's also possible that a knocking sound will arise if the air-fuel mixture ignites on its own rather than through spark plugs, which is a problem that needs to be brought to a mechanic's attention.


When oil gets really low, metal-on-metal contact could cause vibrations to emerge from the engine.


Because overheating can lead to major engine trouble, such as a cracked block, you'll want to be sure that your cooling system stays in excellent condition.

Check Engine Light Turns On

An illuminated check engine light doesn't necessarily mean that your engine is about to fail. Still, it's wise to get to the shop for computerized diagnostics so that any developing problems can be identified before they worsen.

Car Stalls when Idling

A fuel delivery issue could very well be to blame for an engine that stalls during idling. Such a problem can actually put you in a dangerous situation, so it should be addressed as soon as possible.

Discolored Exhaust Smoke

The exhaust smoke's color can give you a hint about the problem that you're trying to identify. Blue-tinted smoke is an indication of an oil leak. White smoke suggests that coolant is leaking internally. Black smoke is a sign that too much fuel is being burned up.
