There was a click when the Wuling Glory Cabin was driving in double rows.

The valve clearance of cold car is large. This is because after the Wuling Glory truck stops for a period of time, the oil will flow back to the oil pan. When the throttle of the engine of Wuling Glory Truck is released after starting, although there is engine oil in the oil circuit, it is impossible to establish effective engine oil pressure at the first time, and there is no effective oil film between components, which causes the engine to make a clicking sound when releasing the throttle. This is a normal phenomenon.
