My type R wont Blow OFF !!!

[Supra-Man18]

I had the type r on the stock twins setup on 15psi and it blew off perfect.. like the boost the twins were pushing was nothing for it.. Then i took it off and went single over the time of a month or month and a half... and i put it back on, and it doesnt blow anything off... Just the " Juh Juh Juh Juh" surging sound.. What could be wrong here...

I'd check the vacuum line going to the bov first, make sure there are no cuts or holes in it and that its hooked up properly.

Is there an adjustment knob or nut on the bov that allows you to adjust it?

Standard or stiff spring? For stiff spring you need to be boosting 18+ psi for it to open. if you have the standard spring you can adjust it to the softest setting. Also make sure you a have a good vacuum source not teed off from anything.

I think the Type R's respond that way. 91-Mk3 also was comaplingin of this. they are fairly quiet.

Tee Vacuum line to the valve is fine as im running a knock off at the moment.. The spring should be the standard spring.. It worked with my twins on 15psi beautifully.. AND the spring setting is loosened all the way to the top...:1zhelp:

BOV's are simple devices. Double check that both of your pressure sources are good and not ported or on one way valves. When I was running that valve it would open when you just rev the motor with the clutch in....

Do you kno how to expose the spring in this valve ? I cant figure out how to open it up...

Took it apart today and found out theres a tear in the little seal around the diaphragm... =/ damnit...

I had the same problem with mine, turns out mine had the stiff spring and i wasn't pushing enough boost. Also that BOV has two vacuum inlets. Supposedly if you want the BOV to work normally only use the bottom and plug the other off but if you want it to regulate how much it needs to open up then hook both of them up. After i put only one vacuum source to it and i put the standard spring in the BOV worked fine. They sound bad ass i love that BOV, everybody nuts when they hear it because now a days everyone and their mom is running a HKS SSQ.

AnyBody believe in this diaphragm fix... Looks like it could apply for the type R bov as well...

I don't know about that fix. It looks kind of ghetto. There is a lot of pressure moving thru there you don't want that to fail again and then you start surging like a mofo. I guess it depends on how much you care about your turbo(s). I'd spend the money and fix it the right way.
