I just hooked up my HKS Blow off valve and for some reason it doesn't seem to be releasing air and it's definitely making no tone/sound. I'm running with the BPV also open for now, but I heard that shouldn't be the problem. Anyone have a clue what could be wrong?

 

Tap into the line leading from the lower charge pipe with a t and feed that to your bpv. There will never be vacuum on the lower cp therefore it will keep the bpv from releasing. Are you running the line that lead to the bpv previously to the bov?

 

I was told to put a T in the line going from the BPV to the solenoid up front and connect the line from the BOV to that. Are you saying I T the line from the lcp and run the line from the BPV to that, I'll just plug it at the solenoid? Where does the line from the bov go?

 

Line from the bov goes either to the port on top of the intake manifold or you can t it off of the line coming out of the top of the intake manifold. The spring that comes with the bov is too strong to work with the solenoid so you have to bypass it. It will throw a bpv code if you remove the bpv solenoid but just ignore it.

 

Which port on the solenoid? Where the BPV hose was originally hooked in?

 

Sorry, I had to edit that, its late, lol. The spring in your bov is too strong to work with the solenoid. You have to bypass it and hook directly into the intake mani.

 

You do not need the solenoid with a bov.

 

Ok so BOV hose straight to intake mani? Or splice it into another hose with a T?

 

Yeap, BOV straight to intake mani. Disconnect the line coming out of the intake mani and replace it with the BOV hose. Connect the bpv to a T in the line coming out of the lower CP. You will throw a bpv solenoid code but just ignore it. You can have your tuner disable it or you can yourself if you have hp tuners.

 

Sorry for all the questions, but will I go into limp mode without the MAF relocate? And what do I do with the hose that originally went directly to the intake mani?

 

Not if you're tuned for the bov. Your tuner will just have to compensate for the rich spike. That hose would have originally went to your vacuum canister and then another hose would lead from the vacuum canister back to the bypass valve solenoid. The other line on the bpv solenoid came from the lcp. If you get rid of the bpv solenoid you can just disconnect the line from the lcp and run a line from the lcp directly to the bpv.

 

Alright what I have done so far, and seems to be working, is the BOV hose straight to the mani with the original hose capped off. Then I have the BPV and LCP hoses T'd together and plugged into the top slot (facing firewall) of the solenoid with the original location of the BPV on the solenoid (left port) capped off.

Is this right? I can't really tell if the BOV is releasing air because my BPV is loud as well.

 

Your BPV should not be working. The BOV should be the only thing releasing air. Try connecting the bpv directly into the lcp without the T, although technically as long as the bpv solenoid is plugged/capped good, it should work the same. Just wondering if your plugs are leaking.

 

Yeah, I definitely still hear the BPV. Maybe if I throw in the BPV block off plate it will solve the problem?

 

That would definitely solve the issue.

 

Gonma text you

 

Ok I have a HKS BOV and the forge BPV hooked up. I bypassed the solenoid as well. I also had the lower charge piping nipple broken off by someone who worked on my car when it was installed.

So I have it set up but putting at in the line from the BOV and the intake manifold so it t's to the BPV as well. At low boost my BPV works and at higher beast the BOV works. Mine runs perfect

 

I'm gonna try and run the block off plate this weekend and see what happens. I'm beginning to think that the HKS itself is the issue

 

a block off plate won't make a difference.
i run my bpv and my hks at the same time.
I WOULD NOT advise doing this as you're going to have 20+ psi surge.

 

Not if OP has the correct spring in his BOV.

 

Nvm, he has the ssqv.

 

his bov sounds like its seized.
after texting him he has it all setup properly. if he puts on a block off plate, in hopes that the bov will magically vta when its seized, it will damage his turbo.

 

Then OP needs to pull it apart and clean it with some silicone based lubricant.

 

I am using a block off plate and using a softer spring inside my HKS bov, I have 0 issues with how it is set up. I am also tuned by Trifecta for this set up. As you can see from the pic I have the bov vacuum line right where the bpv vacuum line would have been hooked up.

 

I'm going to try pulling it apart this weekend and see what I can do, thanks for all the help guys!
