What are the symptoms of a damaged timing sprocket?

[DanteDella]

The severe wear of the timing sprocket may cause the meshing to disappear or lead to the timing chain slipping. Here is an introduction to the related content of the timing sprocket: 1. Function: The function of the timing sprocket is to maintain "synchronous" operation at all times under the connection of "timing" when the engine is running, including the piston's stroke (up and down movement), the opening and closing of the valves (timing), and the ignition sequence (timing). 2. Replacement time: The replacement cycle of the timing belt is almost the same for all vehicles, approximately every three years or 60,000 kilometers. At the same time, the tensioner pulley and idler pulley need to be replaced together because the lifespan of the belt and the tensioner pulley is almost the same.
