What's the proper procedure for testing the bypass valves? Looks like 
mine are stock (and original judging by the "use-once" hose clamps).  
Would failure symptoms be obvious when driving the car? I understand 
they could fail where the don't fully close. Could they be the source of 
an intake leak?
