The engine block of my Smart Forvision makes a thud

If you are in neutral and the engine block makes a kind of roar , there is undeniably a concern. This could be from a loose engine block cover, which repeatedly ricochets on another element. It is also conceivable that a serious whistling sound comes from the belt. If your Smart Forvision does not make a suspicious noise in neutral, but a deaf noise appears when you are driving, the problem most likely arises from bearings and not from the engine block. Do not wait too long to go to a garage, it can get worse.

The engine of my Smart Forvision makes a tractor noise

Your Smart Forvision makes a airplane noise , but without having its performance. Usually this comes from a holey 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 the car makes noise. When this is not the case and the noise does not vary according to the acceleration, go to the mechanic. The problem probably stems from a component of the faulty engine block.

The engine block of my Smart Forvision makes a pan noise

The engine of my Smart Forvision makes a lot of noise

If your Smart Forvision ever produces a lot of noise, it can generally come from two main causes. The first is a thud that will come from bearings . However, it could also come from tires not sufficiently swollen, or even in poor condition. If the engine block produces a lot of noise, it could also come from a problem of fuel combustion, or exhaust hole. Finally, it is quite exceptional that the engine block is the source of this kind of noise.

This is a fairly common and relatively annoying concern. This noise of slam could arise from several components of the engine block. However, here are the two main ones.

  • Poor combustion. In fact, poor or partial combustion could generate clicking noises. Do not engage in repairs if this is what is happening, rather go to your garage.
  • If this noise appears only when cold, it could come from hydraulic lifters .
