Thank you, I changed a valve, helpfully I didn’t crack cover ✌️

I’ve tried to remove this cover but it won’t come off I don’t want to break it. You make it look easy. I have some oil residue inside the vent pipe so I wanted to inspect the diaphragm. Should there be some oil residue Inside the vent pipe?

如果外殼拆壞了，還有救，買個副廠的外殼蓋回去，還能繼續用，只是不保證密封性和原廠一樣。
但是，如果把搖臂蓋上四個角落的扣腳弄斷了，那就很抱歉，只能換新的搖臂上蓋了!
DIY 有風險，請自行承擔。

If this is damaged does it cause the car to smoke?

[@S2D]

Yes, especially when decelerating, blue smoke can be seen in the mirrio.
