I don't know if i have a pressure leak somewhere or if the bypass valve isn't unctioning anymore. Yesterday the jet sound most vortech installs have went away.

Insted of the loud release of air pressure it sounds more like a tire leaking air as it's driven down the road. Has anyone had issues with this?

 

did u check the vacuum connection to the bypass valve?? might have blew off

 

I did, checked the vacuum hose from the fuel presure regulator going into the bypass valve and on up to the intake. even removed the bypass valve to ee if i could manually open and close the valve.

 

if you pushed on the valve with your finger, you f'd it up.

send it in to vortech.

 

are you serious? why would it mess up?

 

Your not going to screw it up by pushing on the valve and opening it ! Its just a spring you would be compressing .

Check all your vacuum hoses , and your intercooler pipes and couplers

 

^^ if you say so,

i pushed in my valve to reseat the o-ring and it was trashed. vortech had to send me a new one.

Its not just a spring, theres a manifold.

 

Ive had mine off and taken apart to put in a new spring . I pushed in on the valve opening and closing it many times . Its still working perfectly

 

interesting. could you go out and push it all the way in now and see if it seals right without taking it apart?

 

i took it in to a shop today and was told the bypass valve was not functioning. have to get with vortech for a rebuild or buy a new one from another vendor.

suggestions?

I have mine I may sell . It does have the lighter spring in it . It opens and closes sooner than the heavier spring . The shop just took it off and replaced it with the huge one on Vortech's site .

 

Ya, make sure you dont push the new one.

i'd send it back to vortech for a repair. It will be way cheaper than buying a new one.

Your BOBPV must have been screwed up or faulty to begin with when you pushed in on it . Your not going to screw it up pushing in on the valve . Think about it , its the exact same thing it does when on your car .

 

if it didnt matter, why would they tape a HUGE warning sticker on the bottom of a new BPV and explicitly says not to manually push in.

ive never opened mine up, so i do not know what the valving looks like. But it worked, pushed in valve to reseat the o-ring, and it didnt seal.

Vortech confirmed by saying valve was messed up.

Again, not saying you are wrong, that's just not my experience

 

Now that you mentioned it [ its been 4 years ] I think I do remember seeing a sticker on the bov when the kit came new . Im just going by that I know I played with the thing....pushing in on the valve many times when I replaced the spring and it still works great .

 

it got fed exed today. the z will be garaged until i get it back. it's good the weather isnt too bad because i'll be on my GSX_R until the z is running. after i get it back i am doing a whole tune-up on the car followed by a UTEC over at SGP in Houston. Nice road trip should do the car some good

 

Yeah, my kit's BOV has a HUGE sticker on it that says it will damage the diaphragm if I push on the plunger.

 

Thw rebuilt one has been on a week now. Definately a lot louder than before, don't know if the threads on the adjustment screw are set the same as the old one. Good thing is that they replaced the bell housing with a red one instead of the blue on that was on there, matches the car better

 

Mind didn't had the jet sound either, my kit is less than 150 miles. I didn't adjust the valve as the instruction metioned, but I used 7/32 hose. Also, isn't true if you have headers, plenum(SSV) mod, the bypass valve will sound differently(no jet sound) ?
