    Watch the video and help me determine what this knocking noise is. It COULD be an exhaust leak, but I'm not sure. The other noise, is coming from ehhh, behind the motor. I was thinking it could have something to do with the torque converter or the flywheel, ect, but again, I'm not sure. Any help would be awesome. Thanks guys!

    Well first off I hope that blue wire in the door jam is fused right.. 2nd Maybe a leak. Are those headers on your truck?

    yes, the blue wire is fused properly, it wouldnt be on my truck if it wasnt.. lol but nope, just the stock manifolds, looking to get headers soon. i looked at all the ports on the heads (with manifolds on) and didnt see any traces of carbon build up where it could be leaking...?
