my greddy type s started fluttering after i installed it again after leaving my car sit for about a month. i tried adjusting it all the way soft to all the way hard still flutter, also tried the single spring mod and still caused fluttering any suggestions?

 

man the stock bov works great put it back on

 

removed 2 spring and put one spring.. it work

 

fixed problem the diaphram had a kink in it for some reason

 

I was going to mention the diaphram, I had one rip on me, cause car to run poor from vacume leak and also would not blow off unless had lots of pressure.

 

Better check it for leaks. They tear very easily.

what's the best way to replace the diaphram?

 

Buy a new one from Greddy and install it...

... i.e. take the cover off and replace it.

On a related note, I will have a Greddy RS recirculating BOV with 2 replacement diaphragms and krytox lubricant available for sale within the next week...
