The engine end cover includes an oil return chamber and a suction chamber inside it, wherein the oil return chamber recovers the oil remaining in the working chamber of the valve body through a suction tube, and the suction chamber removes the leaked gas from the working chamber of the valve body installed in the end cover. The suction chamber is limited between the partition and the top surface of the end cover, which requires the end cover to be sealed to prevent oil leakage from affecting the effect of the shock absorber. Therefore, the sealing of the end cover is crucial to the performance of the car, and the welding process will inevitably result in poor air tightness of the end cover, so it is necessary to test the sealing of the end cover welding.

[0003] However, the prior art still has the following problems:
