This is basicly a very time consuming job rather than a physically hard one to complete. In order to replace the gasket you must remove the intake plenum,throttle body, and misc. vacuum hoses. The wiring harness connections must also be disconnected. Finally the intake manifold is exposed. The bolts holding the manifold to the block are removed exposing the leaking gasket. After removing the push rods and placing them in the correct order to be replaced the gasket and sealants can be removed. Finally replace everything in reverse order. Be sure to consult a GM manual for correct bolt torch specs. The correct specs for the manifold bolts usually come with the gasket. Make sure to change your oil a few times after this job in case any coolant entered the block. Also,change the thermostat and the oil seal on the distributor half shaft cap while you have everything off. Good Luck

The exhaust manifold is right there as soon as you open hood , first disconnect neg batt cab, then jack up car remove bolts that hold pipe to manifold together , unplug any o2 that is in the way and that could get damaged. now from the top take shield off then take manifold bolts out. you might want to spray them with pb blaster and let set a few hours sense exhaust bolts love to break. Remember to use new gaskets installing new one.

Did you find the solution yet? This just happeded to me. But my odometer went out, the blower fan stays on when it rains, and the lights to my shifter, a/c, and stereo are malfunctioning.
