i am noticing some problems with my vortech bpv, it is making a abnormal hissing sound. will it work if i replace the vortech bpv with a greddy rs bov for now? i have a greddy rs bov lying around i was wondering if i can toss that on to see if that changes the problem??

 

did you make sure that the black rubber o-ring on the valve is properly seated in the BPV?

 

i think i've read that Greddy RS won't work, but Greddy S would..
