It should take about an hour to change the intake manifold gasket. This part can be replaced by taking off the intake manifold cover, cleaning the old gasket off and sealing a new gasket in the space and tightening the bolts. When other things are in the way, like the alternator, it will take longer.

Tighten # Tighten the bolts on the first pass in sequence (1-8) to 3 NÂ·m (27 lb in). # Tighten the bolts on the second pass in sequence (1-8) to 12 NÂ·m (106 lb in). # Tighten the bolts on the final pass in sequence (1-8) to 15 NÂ·m (11 lb ft). Use Loc-tite blue on these bolts and follow the above sequence and torque levels.

I'm pretty sure this is that same 3800 motor that gm uses in my mom's 2001 buick Le Sabre. Her intake was the fiberglass resin plastic and the torque specs are 89 INCH pounds. Make sure you use the right tightening sequence too. 89 inch pounds is for the upper intake or Plenum. 136 inch pounds is the torque specs for the lower intake
