Bov

west_side_supra · 04-16-2007, 05:52 AM

ok so this is a issue that had never been solved, bought me a BOV about 4 months ago, and it has never worked. its a HKS SSQV knock off and i have tried about anything to get the damn thing to open. i have lubed the valve and cut the spring to relieve pressure thinking that the spring was maby to hard, i have even taken the spring out and tried to see if would open. the valve moves freely and the only thing that is sticking is a little rubber diphram inside of it on the vacume side of it. ill draw a little diagram showing what the ssqv looks like on the inside. but any ideas would be helpfull.

hmmm so why buy a knock off part for your high performance machine?

I have this BOV and it works beautifully, I love the sound and it is LOUD even with stock 7psi boost.

Now, did you just buy the BOV or did you buy a kit? Because mine came with a little black check valve that goes inbetween-that little nipple that supplies air to chamber B in that diagram-and the hard pipe its suppost to connect to. Because that is how a BOV opens from the vacuum that is created in chamber B.

because the job i was working with only gave me 6.50$/hr my paychecks where about 120-200$
and you know the deal with that, goto pay gas/cigerettes/blah blah blah. and after time you have about 20$ left if your lucky. so i spent 50$ on a knock off.

mm and i bought the kit, it came with the little pipe with the adapter already welded on. it that the little round black thingy that goes on the vacume line. ive been trying to figure out what that was. i threw it out or lost it one of the 2

like this little thingy

thingy

here be another picture

where do i obtain one of these, is that the vacume filter?
