So i bought a Blitz SS blow off valve a few months ago that actually came with the metal pipe its attached to cause the plastic **** broke. Well, it doesnt make any sound. Im not sure if its supposed to or not but all i keep hearing is that particular bov sounds good yet i hear nothing. its a totally stock 89 T2 except that blow off valve and yesterday i put in a new hks air filter......ideas?....advice?....whats going on here?

1. is it adjusted properly? set to the proper boost(opening point)? it may not be opening. so it's not doing it's job.

2. from my personal knowledge the Blitz SS should be fairly loud even at low boost levels...

let us know so we can help you,

Ryosuke

I didnt even put the thing on so to be honest i dont know how its adjusted. If someone could tell me how to do so i would love to check it out....?

im not shure where on the blitz it is, but for the HKS theirs an adjustment screw right on top next to the vacume line.

cool so any idea which way im supposed to be turning this screw or will it be a hit or miss trial and error thing?.....thanks for the help...more?

takahashiRyosukeFC3S

definitely look at the BOV. there will be a screw or bolt with *most Likely* a locking nut on it to keep it set at the setting you decide on. I have the SSQ and the adjustment bolt is right on the back. I'm not sure which way more / less sensative is for your aplication.

take care,
Ryosuke

EDIT: to test i would turn the srew all the way out and rev the engine to get a small amount of boost then let off. if it wooshes then you know that's the most sensative it can be. if not turn it full in and test again.

once you have found the most sensative start turning it in until you are happy with where the BOV releases.

will do....thanks again

alright so does anyone know specifically about the Blitz ss cause when i looked at it i dont find anything to turn...then i found a pic of someone selling theirs and on the top of the bov there is a valve stem and a screw.....mine doesnt have the screw and i think thats where im going wrong....am i right?

shelby4130

or is my whole issue going to be about the spring messing up....i searched about it and hear the piston turns sideways and tears up the inside?....this is annoying either way.....help?

crashdummy

which vacuum did you hook it up to?

takahashiRyosukeFC3S

can you post a pic of your BOV so we can all see exactly what you are talking about?

shelby4130

i will try to post a pic tonight.....oh and how do i do that?....do i need a image hosting site?

there should be a bolt on top to adjust it. I had the Blitz DD and my friend has a Blitz SS, and the adjustment bolt is on top.

does your BOV have custom work done to it? Like did anyone weld over the hold or something. If there is no adjustment screw basiclaly it will not hold boost.

If the screw is missing, that's a leak that won't allow it to create vacuum... You can buy set screws at your local hardware store though...

shelby4130

yeah there is no screw at all....i found pics of the stock bov and next to the vaccum line is the screw but not on mine....i can feel a little hole....the car works fine though....just no sound....what size screw is it?...anyone know?

your vaccum hose might not be connected to the right place, take a pictures of where it is connected to also. and make sure the big hose in the back of the metal pipe is connected to the BAC valve too.

shelby4130

i didnt put it in so im not sure where its connected of the top of my head.....the local shop here in orange county Rotary Reliability did it and im pretty sure theyd do it right....but who knows.....

shelby4130
