having the exact problem but there is no help in any forums with nissan quest. Have had 6 nissans so far and after the Quest have had all my family and friends stay away from Nissan. The manifold would not budge. I think Ford used some sort of paste with the lower manifold gaskets. Had four mechanics tried to take the lower intake manifold from the head and no results. This is the problem when Ford gets involved with anything. All eight bolts that secure the lower intake from the head are out and would not budge. Lifting the manifold also lifts the vehicle completely. I don't think that the gasket would fuse that much to the head that it would not give way.
