Have a 94 5.9L turbo in my Coachmen. In replacing manifold gaskets, I notice that only one port, the third from rear, truly matches up with the head. In each direction, the manifold ports are farther and farther from matching up.
Does anyone out there have a similar Cummins engine, to see if this is normal? The only sensible explanation I can think of for this design would be to accommodate stretching of the manifold when it's hot. Including both ends, it seems to be about a total of 5/16" short. :question:
