2000 3.8 Lower intake manifold (manifold to cylinder head) 1st step is 44 inch pounds, 2nd step is 89 inch pounds. This must be done in sequence.
Here is a link that shows how to replace the intake manifold gasket. Bolt locations and torque settings. Hope this helps.
Correct torque on 2000 model : 18 Ft. lbs.- upper intake manifold [ plenum ].
There is no set torque sequence. Usually, starting with the bolt at the 12 o'clock position, then move to the 6 o'clock, then 3, then 9. Then move to 1, 7, 4, 10, and continue in a clockwise manner until 12 o'clock is reached again. The torque amount for a Silverado is 44 inch pounds on first torque, and?æ89 inch pounds the second time.

I have a 2000 Malibu, I can help you out if you can give me some more info...where on the intake manifold are you referring to?

on top of the motor
Here is the installation instructions for the Edelbrock Performer aluminum intake manifold for a Ford 351M/400...hope it helps out. http://www.edelbrock.com/automotive_new/misc/tech_center/install/2000/2171.pdf
the intake manifold is located on top of the engine, the piece that look like the tubbing is intertwining.
your oil and coolant mix. then you have water in your oil and it makes a white grease. Then the engine will seize if you don't do anything about it. The gaskets is like $30, To put on a intake manifold you need a torque wrench, torque spec and torque sequence. Go buy yourself a Chilton or Hayes manual for you car and read it. If it don't cover it completely, read more and apply what you know and fix the car to your capabilities. Or go spend a lot of money not to get your hands dirty
The only fix for a bad intake gasket is to remove the intake manifold and replace the gasket.
