United Tire and Service News

Most modern engines run quietly and very efficiently. They run so well that you often overlook basic maintenance services and other issues that can lead to engine knocking. An aggravating car engine knocking noise can be very upsetting. Fortunately, the cure does not have to be expensive. Oftentimes, it is something simple that our certified technicians at United Tire can cure with a thorough diagnosis and engine service.

 

Car engine knocking occurs for many reasons. The most likely is when you use lower octane fuel in modern engines. Current engines often have high compression ratios and computerized fuel injection systems that are very sensitive to the type of fuel used.

When a car manufacturer advises using higher octane fuel and you choose to cut costs with regular unleaded, your car engine might rebel. Instead of burning fuel cleanly and efficiently, the lower-grade fuel delivers less power and more exhaust that causes problems under the hood. A tune-up and using recommended fuel is a simple cure.

 

You need to maintain the engine to ensure it runs its best. If you skip engine tune-ups and let the air filter get clogged with dirt, your engine might start knocking. The same goes for a clogged fuel filter that sends either too little fuel or unclean fuel to the fuel injectors.

You also might find the alternator is not sending enough power to your motor. If the plugs are working at less than ideal capacity due to reduced electrical power, your car engine might rebel. A recurring knocking could be the problem—especially when accelerating. Regular car care helps to ensure that will not happen.

 

Sometimes, that engine knocking sound is a bigger problem than bad gas or needing a tune-up. If your car ever ran low on oil or coolant and the engine overheated, you might have bad wrist pins on connecting rods that became bent due to heat. One or more bad valves also might cause an engine knock. You might have other underlying mechanical issues that cause the knocking sound. Fortunately, those are relatively rare. When such problems do arise, costly repairs typically are in order. You also might need to replace it. We can help you decide the proper course of action.
