First time it happened I shat myself because I was giving it a bootful on a freeway on ramp and it sounded like a police siren! I thought it might be the BOV because it happened when I was backing off the loud pedal. It doesn't happen all the time and the car is otherwise running normally and boostin well. Today it happened under about 75% throttle. I backed off and then gave it a bootful but it didn't repeat the sound. Car has done 175K kms Link to comment https://www.fordxr6turbo.com/forum/topic/86422-weird-intermittent-turbo-noise/ Share on other sites More sharing options...

The reason I was thinking BOV is because it sort of sounds like the whirring/whining whooshing noise you hear from ricer cars when they are changing gears. I sh*t you not though - I could have sworn it was a cop siren in the distance behind me when it first happened!!

Same with bent fin or bearing problems...I don't know enough about bovs to be sure but can they get stuck - ie not open enough and create different noises?

Is it possible there was a temporary obstruction in the BOV?
