For a vehicle owner there are few words as scary as engine repair. If a mechanic mentions this phrase it immediately brings thoughts of extensive and expensive services. While some engine trouble may occur completely unexpectedly there are other issues that will provide warning signs long before they become dire situations that result in these big bills. If you run into any of these signs of major engine trouble be sure to contact your local mechanic in order to have them repaired prior to bigger issues arising.
Perhaps one of the first signs of trouble you may run into is a knocking noise that occurs under the hood while your vehicle is running. This is the sound of the engine bearings clanking as they wear out, which can happen due to general high mileage or if the engine is operated with low oil levels. The engine bearings are what all of the moving parts of the motor rest on, and should they become worn they’ll need to be replaced, which may require a partial rebuild of your vehicle’s motor.
Excessive Exhaust Smoke
Another sign of trouble can be easily spotted with your eyes. Excessive amounts of colored exhaust smoke will indicate one of several problems, depending on the color. Black smoke indicates too much gasoline is being burnt, blue smoke is a sign of an oil leak inside the engine and white smoke indicates a coolant leak. Any time your vehicle is producing large amounts of exhaust head to the auto shop to see what the problem is.
Decreased Fuel Efficiency
A drop in your MPG’s can be caused by numerous issues, some much more serious than others. It may be as simple as something such as a clogged air filter, but it could be a result of more intricate engine issues.
Lack of Power
Another fairly general symptom of trouble is that a lack of power and performance. If your car is now having trouble getting up to speed, has a rough idle, or needs several minutes to warm up prior to being able to drive properly there’s a good chance that some sort of engine trouble is occurring.
