Just got done installing my bbk intake. When I started it it sounded like a vac. leak so I pulled the intake and double checked everything but when I reinstalled it it now sounds like valvetrain noise? Was wondering if anyone had any idea's of things to check or previous experience.

 

Did it throw any codes or anything? It's fairly common to hear the intake sucking or whistling, especially if you still have AIR.

Post a video or something so we can help you pinpoint what's going on.

 

Pulled car out and saw my egr gasket sitting on the ground, that fixed it
