hey Scotty. I have a 2002 Chevrolet Venture front wheel drive that I have been trying to nail down an exhaust leak, I replace the o ring at the rear exhaust manifold and it still sounds like it's coming from the same place, could it be coming from the cross over and if so how do i go about getting to that part of the manifold?. thank you from a loyal viewer

do this video, it can find exhaust leaks too https://www.youtube.com/watch?v=zMok2y05jNE&t=40s
