What happens if the small chain tensioner is damaged?

[DelJohnny]

Damage to the small chain tensioner can result in increased fuel consumption and bearing failure. Increased fuel consumption due to small chain tensioner damage: A faulty tensioner can cause issues such as increased fuel consumption, lack of power, and engine knocking. The tensioner acts on the engine's timing belt or timing chain, guiding and maintaining optimal tension to ensure proper operation. Bearing damage in the small chain tensioner: The tensioner pulley contains a bearing. If abnormal noises occur, it indicates bearing failure, which may lead to timing misalignment, ignition and valve timing disorders, affecting the vehicle's normal operation. Warning signs of small chain tensioner damage: Timing chain failure disrupts the engine's designed management logic. If timing misalignment occurs, the engine may not function properly, leading to symptoms like unstable idling, poor acceleration, or failure to start.
