6 Indications of Serious Engine Trouble

So long as you keep up on maintenance, you’ll be doing your part to help prevent the onset of serious engine problems. But even if you pamper your vehicle, it’s still possible that trouble could arise in this department. And if it does, you’ll want to be able to identify the symptoms so that you know to quickly get to the mechanic. Here’s a look at six must-know signs of serious engine trouble.

Knocking Sound

A repeating knocking or tapping noise could be an indication that your oil level has gotten dangerously low. In this scenario, it’s possible that simply adding oil will take care of the issue. However, this symptom could also mean that you’re going to need a rebuild on the bottom end of your engine.


Vibrations stemming from your engine could also suggest low oil, with metal-on-metal contact causing this symptom.

Check Engine Light Turns On

While something as trivial as a loose gas cap could cause the illumination of the check engine light, you’ll still want to get to the shop to make sure that something major hasn’t started brewing.

Loss of Power

If your vehicle has entered its golden years, there’s not really reason for concern if it has gradually lost a bit of power over the years. However, if the loss of power is sudden and drastic, then it’ll be best to visit a mechanic.

Decreasing Fuel-Efficiency

While a number of automotive issues can cause worsening gas mileage, one possibility is an issue with your engine’s compression stroke.

Excessive/Off-Colored Exhaust Smoke

Whenever exhaust smoke seems to be the wrong color, it’ll be worth further investigation. White smoke suggests a coolant leak. Black smoke could be an indication that your car is burning an excessive amount of fuel. If the smoke is tinted blue, then there could be an oil leak.
