Having an engine issue is one thing you don't want your mechanic to tell you. The engine is the main component of your vehicle and one of the most expensive to repair and replace. An engine problem can sometimes be something very simple, such as a bad battery or an alternator, or it could be something much more complex, such as valve repairs or a complete engine replacement. If you have an engine problem, it's something you need to have looked into right away. Read on for signs that you may have an engine problem. 

1. Vehicle Not Starting

If your vehicle isn't turning over, it may be a concern with your battery more than your engine, although your engine could also be the problem. You could have an issue with your alternator, which helps give power to your engine, much like your battery. If your vehicle isn't starting, you should have both your battery and your alternator tested. You can have this done at your local auto parts store, or you can take your vehicle to an auto service shop to have it repaired.

2. Knocking Noises

If your vehicle is making knocking noises, it may be doing this because you don't have any oil in your engine. If your vehicle is out of oil, it can create all types of problems for your vehicle, including bending your valves and wearing out the timing chain guides, which can also cause the timing chain to be off. If you are hearing any type of knocking noises, or it sounds like your vehicle is making other odd sounds, be sure to take it to a repair shop to have it looked at. 

3. Smoking Or Odd Odors

If you see smoke coming from under the hood, or your car emits odd odors when you are driving, it could be an engine problem. Your vehicle may be overheating, which can be caused by not having any anti-freeze in your vehicle, or it could be because of a thermostat problem. If you smell any odd odors or you see smoke, take your vehicle to an auto repair shop immediately.

If you have a problem with your vehicle's engine, you need to take it into a repair shop to be inspected and diagnosed, then repaired as needed. Don't wait to have your engine repaired, as it could result in more problems that can add up quickly. For more information, contact an auto repair shop near you to learn more.
