Shouldn't the passenger side go to the "vacuum source" too, via a T connection combining both valve vents? If I put a "breather" on the passenger side, isn't that breather going to let engine fumes in to the engine compartment as well? Can I just plug the present valve cover vent until I get it properly fixed? The reason I'm asking is that the fumes from the valvecover seems to leak into the coup�.
