I was just wondering if anyone on here has had any issues with blowing out the diaphragms on the one way check valve's either the one by the fire wall running from the Throttle Body or the one way check valve running from the head? If so is there any solution such as a check valve that can handle more pressure with a stronger diaphragm that someone has came across? I have searched quite a few places and yet been able to find one. Or is there a more simple solution. I look forward to hearing some input on this as I am not having to replace these things on a daily or weekly basis or anything but if I could find a strong one that would last a long time and might even be able to take disassemble for cleaning that would be nice. Thanks for everyone's input in advance.
