Then you got a defective one. Send it back, get ur money back and buy the real HKS BOV and you'll be problem free.

i dont think its defective, i think its just not getting enough vacume. or maby not enough boost to make it blow off.

i dont think thats the case here,
are u at stock boost levels?

and jus dont buy knock-off anymore
there's a reason why they call em knock-offs
their fake
not the real thing
crap

if u could see who sold u the thing u should knock-him-off his feet
for selling u this (jus kidding)
thats probly why it was on ebay, cuz it doesnt work

stock boost=yes, im still looking for a cheap Electronic Boost controller < hard to find. um and also what kind of BOV would you recommend for stock boost levels

this is the kind of bov knock off i got

Well the reason it doesnt work is cause you payed 3.99 for it. At least get a 40$ ebay BOV lol. It will probably never work right because the seller bought a cheap defective bathc of BOVs to sell on ebay. But I agree, Save for a real SSQV or a cheaper name brand BOV maybe. If your just after sound go with the ssqv because it is quite loud and sounds nice. Or the turbo XS bov with the horn insert is pretty loud and nice sounding too. Or if you get a knock off at laest get one of the 40-80$ ones, because they really work.

Actually, If you want, Ill sell you my ebay BOV for 30$ shipped. It works great, It sounded just like the stock bypass valve, but much louder. But im replacing it with a real SSQV when my car is back on the road. Ill get some pics of it for ya.

Why not just get a Bosch BPV?
They work great, hold tons of pressure, and are cheap... hmm, seems too good to be true? oh wait, they're not blingy... they're black plastic. so that's probably why it's so far out of the vocabulary of so many people. It's not polished aluminum, or anodized blue/purple/gold/red/pink yelling "look at me! i'm not stock!"

Personally, stick with what works and you'll be fine.
If you really want an HKS BOV, buy one.

You should take yours apart, and polish the shaft, polish the housing, grease it up, and put it back together. It'll work fine, I'm almost sure of it.
