Check Valve.

[StealthX]

Hey forum

Couple weeks ago I installed an idle control valve, it's running from a vacuum port on the manifold and uses a 5/8 heater/vacuum hose. The unit is a bosch two wire PWM.

I have boost escaping through it, making a funny noise - I'm confident this is what the noise is - does anyone know where I can buy a one way valve to put into the line to shut when I reach boost?

What am I looking for and where can I buy one!?

Thanks!

Cam.

The hose on the break servo line on some cars have a one way valve on them although I think this would be to big. Also when I worked at Vauxhall in the uk, which is General motors there was a recall for the washers on some of the models (vectra/Astra). The fix was a one way valve on the small hose to stop the water from running back into the washer bottle. Maybe try Holden.

Thanks mate I'll try some dealerships then, I might just be looking for a PCV valve maybe?

Any other advice?

PCV valve is a one-way valve, the brake booster on our Nissans (probably only the turbo ones) have a one way valve as well.

Just hook the inlet side of your idle control valve to the cooler pipe just before the throttle body.

this is exactly how it should be and its how it is on every nissan ive worked on
