"At normal running temp the torque is 105-110 ft/lbs. 130-135 ft/lbs for turbo models. The pattern is basically a middle to each end pattern. First the middle-single bolt on the exhaust manifold side of the engine, then the two bolts on the injector pump side in the middle, then back to the manifold side one bolt out, etc. Work your way one bolt at a time from middle to each end. That is, one bolt towards the end on each side until you get to bolt number 25."
