just fitted a BOV to my s14 and it doesn't work. i bought the item off ebay. i was promised that it worked. i seeked advice from a guy at a local performance garage (not the best place in the world) and i was shown where the vacuum pipe should be placed but i don't trust his knowledge. He seemed a bit dopey. As no instuctions came with the valve it's just been a guessing game so if any 1 can help me i'd be very apreciative.
