Can someone tell us if all four of these channels are supposed to be open and clear. As you can see two are not. Actually this picture was a week ago and now we have the one on the right side clear but the one on the back side is like welded closed or something. Also if someone could be nice enough to explain exactly how the exhaust manifold works on the 800 stringer v6 I would appreciate it. I mean like the flow of water and exhaust and how does blowing an exhaust gasket ruin your motor. I have researched it and read all I can find but I need someone to explain it a little more in lay terms maybe. Thank you.
