I have to change the fuel pressure regulator on my pontiac, which means I
have to take off the intake manifold. I am having a hard time finding the
torque specs. Also, is there anything else I need to do I am not thinking of.
Thanks

This in general for that series engine, all through the 90's:
I thinks it's 18 ft-lbs for the upper intake. You don't need to remove
the lower. That coolant pipe that goes from the water pump all the way
around the back of the engine has two little coolant hoses that go to
the throttle body, which is attached to the intake. It's best to leave
the throttle body attached to the intake which means that pipe needs to
come off, and it will need a new o-ring when you put it back in at the
water pump end. Also, those breather and PCV hoses often have rubber
ends that are so worn that they won't want to stay in place when you try
to re-install them. The map sensor is blocking two of the upper
manifold bolts. That's all I can think of.
