Worn-out Components: Over time, various engine components such as belts, bearings, and pulleys can wear out. This wear leads to increased friction and subsequently generates noise. Regular maintenance can prevent such issues.

Lack of Lubrication: Engine components require proper lubrication to reduce friction and prevent metal-to-metal contact. Low or degraded oil levels can lead to noisy operations as components rub against each other.

Exhaust System Problems: A malfunctioning exhaust system, including the muffler, catalytic converter, or exhaust pipes, can result in loud rumbling noises. These issues can also impact the engine’s performance and fuel efficiency.

Ignition and Combustion Noise: Knocking or pinging sounds could indicate problems with the combustion process, such as improper fuel-to-air ratios or carbon buildup in the cylinders.

Loose or Damaged Parts: Loose or damaged engine parts, like heat shields, can create rattling or metallic clanking sounds as the vehicle moves.
