Is the Impact Significant if the VTC Actuator Abnormal Noise is Not Resolved?

[StephanieMarie]

VTC actuator abnormal noise not being resolved has significant impacts. The abnormal noise from the VTC actuator indicates that the technical state of a certain mechanism in the engine has changed. The primary reasons include excessive wear of some parts or improper assembly and adjustment, which can directly affect the engine's lifespan. Symptoms of VTC actuator abnormal noise: 1. Engine abnormal noise: There are many possibilities for abnormal noises coming from the engine compartment. Most people can identify the noise as originating from the engine compartment based on the sound source, typically characterized by a metallic screeching or a whistling noise. 2. Transmission abnormal noise: If there is a rustling sound inside the transmission while driving, which disappears when the clutch or accelerator is pressed, and a whistling-like sound occurs during gear shifting.
