Hello
I have been have problems with my fd since i took the double throttle butterflys out. Found out the problem the check valves have stoped working not letting any vacume through anyway what so ever. My question is do i need to use the one way valves or can i just leave them out? Also where could i get a couple of them from? Do the mazda dealers normally keep them in stock? and how much?

You DEFINITELY need the check valves.
Dealers will probably expensive (but new)
I bought some last year second hand from Jimmy\'s for £15 each.
For my current car I got mine from Dale Clark on rx7club.com. Delivery was lightning quick. $25 shipped for 4 valves.

As the advert says, they are a little loose, so you should probably use 3.mm hose for the lines with valves in them.
These are pretty heavy duty though! http://www.rx7club.com/showthread.php?t=164819&highlight=viton+check
Just recieved my new check valves form mazda and they are very very heavy duty and made out of stanless steel. So thats why they cost £23
I have never seen the stainless steel check valves. Would you mind posting a pic?
cant post but i can email it to you
