Hey Bolt, so i have the same problem with my valve and came to find this topic and your solution, wich i suspected that the fault was the oring. I used one but came from Temu, so that didnt work.. The thing is that im from Portugal. Is there any way of sending some, like 3 or 4? And how much do you want for them? Or where did you get them? Much apreciated.
