HKS SSQV

[Jonson]

Ok, I've got a HKS SSQ on my VR4, had it on there for ages, but it never vents.

I've pulled it apart, the diaphragm is good, I lubed the pin/slide thing, everything looks ok. I sealed the main O ring on the flange. Changed the spring tension. Still no change.
I even swapped it with an identical one mate has off his car it didnt work, although it did actually vent for about 3kms then stopped working again.

So I'm thinking it has to be Vac source. I've had it run dedicated and shared lines off the 2 vac nipple on the front side of the Aus spec inlet mani, still no difference. I haven't tried the single nipple(jap throttle body) above the TB as the source needs to be behind the butterfly from what I know.

So my question to people is where the **** do you get the vac source from for a SSQ? The car is a JDM VR4, with Aus inlet manifold, JDM TB, Evo 6 cooler w/ custom piping.

Any help to get this ****** to vent would be great. Then I can change it for a plum back.

Have you tried replacing the fin? Do you have the factory one in there or another colour??

My mate bought a 2nd hand SSQV with a gold fin in once, and it wouldnt make ANY noise- then I changed it around with a stock fin (silver) I had lying around and it started making noise!

I get the vac for mine from the Inlet manifold Jon. The source is just under where it says "eci multi". I'm also running the latest ssqv.
Mine does seem to have a non-return valve in the vac line though.

 

[Jonson]

Yeah, changed fins too. From then normal silver one to a purple one, no change. Ah ok Tim, what way is the valve facing? That would make some sense I think.

 

[brisvr4]

There is a thin side and a thick side to the valve Jon. The thin side points towards the bov and the thick side points the other way.
I can't find my bloody camera cable, when I do i'll toss the pics up mate.

 

[Jonson]

Thats cool mate. I'll figure it out. I'll grab a valve tomorrow. Tried 4 places today in my area, not a single person knew what a 1 WAY VALVE is.....there is no secret meaning or tricky names.....Idiots.

 

[Jonson]

Ok, put the 1 way/check valve in, no difference either direction. Any more ideas?

 

[brisvr4]

Try hooking the bov vac source to your boost gauge and see if it is actually working Jon.

You should be the mechanic not me
