Reasons for cars’ rattling noise

Rattling Noise Main reasons for rattling noise.

Step by step engine assembly

If you spot any of the following symptoms, RNK Engineering recommends having your vehicle checked to prevent more costly problems from developing.

• Rattling, pinging or knocking noises. When spark plugs begin to misfire, you may notice unusual noises from the force of the pistons and combustion not working properly. Pistons travel at high velocities; if the spark plug fires at the wrong time, this could lead to constant rattling, pinging or knocking sounds.
• Hard vehicle start. If your car is having trouble starting or just feels disjointed and jerky, your spark plugs may not be working right. This can lead to misfires and erratic performance.
• Reduced performance. Spark plugs fire when you accelerate and change gears. If the spark that the plug generates isn’t functioning at 100 percent, your vehicle performance will be poor, and you’ll experience a sluggish and fuel-wasting drive.
• Poor fuel economy. Lots of things can lead to poor fuel economy. In the case of old spark plugs, fuel is wasted because your vehicle fails to receive the proper, heat-generating spark at the right time.
