5 Common Signs Your Car Needs Engine Repair


5 Common Signs Your Car Needs Engine RepairWhen it comes to car trouble, few things are as frustrating as problems with the engine. While many people believe trouble under the hood is going to cost an arm and a leg, issues can often be resolved quickly and affordably, as long as they're addressed in a timely manner. If you encounter any of these common signs of engine trouble, it's important to visit a local auto repair shop ASAP for proper diagnostics and service.

Decreased Performance/MPGs

There are lots of things that can deplete performance and cause your vehicle's fuel efficiency to plummet, many of which are not related to the engine. However, if you experience a sharp decrease in MPGs, or if your vehicle has trouble starting, idling or accelerating, it's likely time for engine repair. Head to the shop for proper diagnostics.

Excessive Exhaust Smoke

A vehicle that is producing excessive amounts of exhaust smoke is likely suffering from issues with its engine. You can often tell what the trouble may be based on the color of the smoke. Blue smoke is an indicator of burning oil, black smoke often means too much gasoline is being burned and white smoke is a sign that coolant is leaking into the combustion chamber.

Knocking Noise

A knocking noise that is coming from your car's engine could be a sign of failed engine bearings. These bearings support the motion of the moving engine parts, and should they fail the engine could seize. This could likely be a sign of poor engine lubrication. Head to the auto shop for proper diagnostics.

Oil Leak

Nothing should ever be leaking from your car, so if you spot a drop, head to the shop. Oil leaks are detrimental to engine health as they indicate that there isn't enough oil to properly lubricate the moving parts in the engine. Quickly addressing leaks will ensure that your vehicle's motor does not suddenly grind to a halt.

Check Engine Light

The check engine light can represent a long list of issues, but many of them are quite minor. Early diagnostics are key to preventing small problems from growing much worse. What starts as a failed oxygen sensor or MAF sensor, could lead to a malfunctioning catalytic converter, which is much more expensive to fix.
