Top Signs of Engine Trouble

Top Signs of Engine TroubleIt is easy to understand why the engine of a car is often compared to the heart of a living organism. While the heart is pumping blood, the engine is pumping its pistons up and down, creating the power necessary to move your vehicle. If you felt you were having heart trouble you'd certainly visit a doctor, so why not head to the mechanic if you believe your car is having engine trouble? If you notice any of the following signs of engine trouble be sure to visit your local auto shop as soon as possible.

Knocking Noise

A knocking noise that rises and falls in sync with engine RPMs can often be attributed to worn engine bearings. These bearings are what support the motion of moving engine parts, and should they fail, which they most often due to because of a lack of lubrication, the engine can suddenly halt. This of course can result in the need for an engine transplant or rebuild.

Increased Exhaust Smoke

Have you noticed excessive amounts of exhaust smoke coming out of your car's tailpipe? Judging by the color of the smoke you can often determine what type of issue your car is having. White smoke may indicate coolant is being burnt up in the combustion chamber, blue smoke indicates burning oil and black smoke means too much gasoline is being used.

Decreased Performance

A drastic drop in performance can be a sign of engine trouble both major and minor. Many times rough idles, stalling and decreased fuel economy can be attributed to small problems, such as worn spark plugs, failing ignition coils or clogged filters.


Nothing should ever be leaking from your car. If you notice a drip from your vehicle be sure to visit a mechanic ASAP. The leaks most commonly associated with engine trouble are oil leaks and coolant leaks. Oil is necessary for proper engine lubrication and sufficient coolant levels and needed to prevent engine overheating.

Check Engine Light

One sign of engine trouble that will stare you right in the face is the check engine light coming on. This light is often feared, but should be thanked. Many of the issues that trigger it are relatively small, such as a failed sensor or even a loose gas cap. However, if left unchecked, the problem will get worse.
