Can Yinglang pass the annual review of replacing the aluminum cover of the valve chamber?
I can't.

The aluminum cover of the valve changing chamber of the general engine is made of metal, and it is only sealed by rubber strip without sealant during assembly. It will have a good seal. It is feasible to replace the front bumper after approval, but modifications such as raising the chassis to improve the off-road performance of the car are not allowed. Once illegal modification is found in the annual review, it must be restored to its original state.
