Why you ask.
The dump side stays open when under vacuum.
So when you drive DIRTY unfiltered air goes into your motor via the dump tube tru the diverter valve.
BIG NO NO.
Didn't you notice the vacuum suckting on the pipe you disconnected?
you do realize that whats in every car is the same thing as a BOV it just sends the air back to the intake rather then outside right? it does not "suck" air in from that tube
