My BOV which is a stock OEM lets boost out at idle and low rpms. Is this normal?

I just had to replace mine as it wasnt holding boost. I think they are only rated to 12 psi or something anyway? mine held 20 ok for quite a while though... 1 Link to comment https://www.fordxr6turbo.com/forum/topic/91318-bov-leaking-at-low-rpm/#findComment-1567231 Share on other sites More sharing options...

You wouldn't normally have boost at idle. Is it leaking air at idle?

Grego.77 Member 195 Member For: 10y 5m 26d Gender: Male Location: St Clair NSW Posted 09/12/15 12:39 PM Author Share Posted 09/12/15 12:39 PM While on the dyno It was hissing a bit of air, had an old $30 Chinese bov sitting around which fitted straight up and has solved the problem. The Chinese 1 seems to have a spring which is a bit to tough and now at low boost deceleration the turbo is making that anoying flutter sound. (very light throttle) But works when open so I guess it couldnt be doing too much damage.
