What are the symptoms of timing misalignment?

[DeEmerson]

Here is a detailed introduction to the symptoms of timing misalignment: 1. Excessive clearance: When the car is idling, there is a slight noise; the noise becomes obvious at medium speed; at high speed, the noise becomes chaotic or disappears; when accelerating sharply, the noise reappears, and in severe cases, the timing gear cover vibrates. This indicates excessive clearance in the timing gear meshing. 2. Insufficient clearance: After major repairs or replacement of the timing gear, there is a continuous noise. The higher the speed, the louder the noise, especially when accelerating sharply. This indicates insufficient clearance in the timing gear meshing. 3. Uneven meshing: When idling, a rhythmic noise can be heard, which increases with higher speed. This indicates uneven meshing of the timing gear. 4. Axial displacement: When idling, there is a clear, rhythmic metal impact sound, which worsens with higher speed. This indicates axial displacement of the timing gear or damage to individual gear teeth.
