Just noticed while my car was idling that my Tial Q 50mm BOV was open. Isn't it supposed to be closed at idle? I did some research and got some mixed opinions. Seems to me that if it is open at idle that would cause a bit of a vacuum leak? Our cars pull around 19" at idle which means I should have the Unpainted tial spring. I took the BOV apart and it looks like I have the Black spring which is designed for motors that produce 8-11"
Should be as simple as swaping out the spring for a stiffer one correct?
