BMW N13 F20 116i PCV Diaphragm Replacement

搖臂蓋 PCV 壓力調節膜附近總是油糊糊的? 踩油門會有噓噓的吸氣聲? 有以上症狀也許是 PCV 膜破了! 原廠是更換搖臂蓋與油封，我打算只換 PCV 膜，很遺憾原廠不單賣 PCV 膜，只好淘寶上拍一個自行更換。影片記錄了更換過程，Mini 的 N13 也適用。如有幫助，請給個讚，謝謝!

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

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。

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?

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

[@S2D]

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