6 Symptoms of a Major Engine Problem

6 Symptoms of a Major Engine ProblemBy keeping up with maintenance, you can reduce the risk of engine trouble developing. But if engine issues do emerge, you'll want to be able to recognize the signs. This way, you'll know to promptly get to the mechanic so that the issue can hopefully be resolved before it causes your engine to fail. Here's a look at six common signs of major engine trouble.

Knocking/Tapping Sound

A dangerously low oil level could lead to a knocking sound that arises from an absence of lubrication. While it's possible that simply adding fresh oil will take care of this issue, there's also a chance that the bottom end of your engine will need rebuilding.


If extremely low oil causes metal-on-metal contact, then vibrations could start to emerge from your engine.

Check Engine Light Turns On

When the check engine light illuminates, it doesn't always mean that you're on the brink of engine failure. Nevertheless, it's smart to promptly bring your vehicle to the shop for computerized diagnostics so that any developing problems can hopefully be nipped in the bud, saving you from much more expensive repairs.

Excessive/Discolored Exhaust Smoke

Whenever exhaust smoke looks off in color, it's best to try to determine the underlying issue. Blue-tinted smoke suggests that oil is leaking. White smoke is a sign of leaking coolant. Black smoke is an indication that an excessive amount of fuel is being burned up.

Worsening Fuel-Efficiency

While there are many types of car trouble that can cause reduced gas mileage, one serious issue to consider is that there's a compression stroke problem.

Loss of Power

If you drive an older vehicle with high miles, it shouldn't necessarily be concerning if it has slowly lost a bit of power as the years have passed. But if your vehicle's power loss is sudden and dramatic, then you'll want to visit the mechanic for diagnostics.
