It is also conceivable that a severe humming noise comes from your belt.

The engine of my Toyota Prius 4 makes a tractor noise
Your Toyota Prius 4 produces a airplane noise , but without having its power. Often, it comes from a drilled or damaged exhaust pipe, not from the engine block. The noise should be louder and more serious than normal, but dependent on acceleration. the more you accelerate, the more noise the car produces. If this is not the case and the noise does not vary depending on the acceleration, go to your car repairer. The problem is likely due to a damaged engine block component.

- Poor combustion. And yes, poor or partial combustion could cause clicking noises. Do not embark on repairs if this is what is happening, go to your car repairer instead.
