when i installed my aem fpr i was revving the throttle under the hood checking for leaks , and i noticed my BOV sounding wierd , and when i gassed it and held onto the charge pipe , it felt as if somthing was hitting the charge pipe , like the piston inside or somthing , can sombody explain what that might be?

 

well if your bov is still working it probably isnt. all u gotta do is take it off the charge pipe and check it. push the piston up and down with your finger and if its still smooth and stuff its all good

 

ill do that thanks
