I have an 86 SVO, I recently purchased the dual piston blow off and the t coupler, I installed it but the valve never opened no matter what I tried, did I do something wrong? I I bought a 1/4' tee fitting and 2 pieces of vaccum hose so everything would be plugged up properly, I plugged up the valve with a hose that was tee'd off the intake manifold hose, but still no whoosh noise, the valve isn't defective either. help?

Where does the vacuum hose go to on your install?

Where does the vacuum hose go to on your install? (i used the vacuum that goes from the intake manifold to the fuel pressure regulator) |

I don't like "stealing" a signal from such a vital device but it's a valid source. Where did you put the Tee?
I've never seen it happen but are you sure there isn't a piece of silicone in the Tee that is blocking the opening to the 1" outlet? I've seen a few that were partially covered that I had to clean out before shipment.
When you have the BOV removed to check that, push the valve open with your finger to ensure it's not stuck.

I made it a 3 way split, one connected to the fuel regulator, one connected to the intake manifold and the other on the valve. the tee connects all of them no problem but the valve just doesn't open, I even tried putting the fuel pressure regulator hose directly on the valve just to see if the valve maybe needed more air but to open up and nothing... the valve isn't stuck either, it's so strange cause I've seen tons of people do it similar to this and if works fine.

I don't see anything, in the tee, the valve pushes open as well, I'm not sure why it's not blowing off |

The valve that is visible through the vent hole will open under vacuum allowing you to see through them. Does this happen when under vacuum at idle?  |

Yep, that was going to be my next question if the first valve would push open (which it does).
My next question is how much boost are you running when you let off the throttle and aren't hearing a release?

okay, so I tried it and the valve is stuck, it's not opening.

One of the o-rings in the upper valve may have rolled out of it's groove. Caution: the primary spring in the valve is under compression, once you remove the Allen screws hold it together tightly in a controlled area.
Without spring pressure, see if you can slide the inner valve freely inside the upper housing.

(I removed all the Allen screws, but the valve wont come apart, not even if I try and force it open lol, I was gonna try and open it up with a flat screwdriver but I don't wanna damage it, I'd rather exchange it for a new one, if I can) |
