Hey forum :P

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.
