Hi there, my car (94 WRX import) has started idling high recently. I started it up earlier today and opened the bonnet just have a wee look/listen to try to diagnose anything. I know it could be an endless amount of things, one of which being a split vacuum hose. When I opened the bonnet I heard quite a loud hissing noise, I located it to be coming from one of ports on the inlet manifold:





The blue hose is going to the fpr. and the black one going to the boost solenoid, the other port on the left(with no hose on it) was the one making the hissing noise.

Does anyone know... if it should be connected to something? What it should be connected to? etc. etc.

I have a standard re-circ valve, rather than a dung valve btw

Dump valve actuator vacuum feed.

Need to go to the vacuum feed on the recirc, this pipe is usually where boost gauges get spliced into too.

Ha we have the same name!

Thanks for the advice, is it definitely the same between the standard recirc valve and an aftermarket BOV?

Yep, as it needs the vacuum feed to tell it when to open.
And yeah I`d noticed you had the same name lol, I thought I didn`t start this thread lol.
