Can anyone tell me what is wrong. My truck is making the exact noise. This video isnt my truck but same circumstance. I thought it was a manifold gasket or cracked pipe but I replaced gaskets and took out the headers to look. Would it possibly be a head gasket? The noise is coming from driver side exhaust area. Thanks
