I've removed the intake manifold from my 85 12a to fix a coolant leak. The factory workshop manual is very specific about the torque values and torque pattern for the water pump but not so clear about the intake manifold. I believe the intake manifold torque amount is 14-19 ft-lb but I can't find anywhere where it specifies a torque pattern. Is there a specified/recommended torque pattern for the intake manifold? Thanks.

 

I've always torqued the intake manifold from the inside out. Meaning, I tighten each of the inner (towards the center) fastners first and work my way out and back diagonally. Once the fastners are drawn in, I go back over them and torque each to spec.
