So I removed the other two bolts you mentioned, for a total of 12 bolts removed from the intake manifold. EGR tube is unbolted, and I removed the two sets of plastic tubes. The whole thing wiggles slightly, but then there is a very solid thunk and it does not go any further. I've tried a pry bar under the thermostat housing, and under the bosses on the other side as well, and it does not budge! What am I missing??? The only bolts that seem to still be in, in that area, are the engine mount bolts.
