So im working on my car, and i noticed that during idle the Forge BOV valve is 25% open!
So i rev'ed the engine and the valve appears to be working properly / moving freely. Also i figure the BOV is not pushing out air but sucking in air at idle.
My best guess is that the intake manifold has a vacuum at idle where pre-throttle blade the pressure is neutral, so the vacuum is pulling the BOV open.
What do you guys think?
