When the car first starts moving, the reasons for abnormal noises are as follows: 1. The car has not been used for a long time: The engine oil will return to the oil pan, meaning the top part of the engine, specifically the valve chamber, will have less oil. Because the valves lack the sealing and lubrication provided by the oil, abnormal noises can be heard from the bottom of the car when it first starts. This situation is normal. 2. Issues with the engine belt: Abnormal noises from the engine belt are usually due to the belt being dirty. Cleaning it with water or applying some lubricant can eliminate the noise. However, whether this solution is suitable for all car models requires further analysis.
