Intake Manifold Gasket Question

[Chuckles]

A while ago my mechanic (who I have never had a problem with) told me that the intake manifold gasket and water pump needed to be replaced and that because the manifold gasket was cooked, coolant was getiing into the oil or vice versa. He also told me that it would not be a good idea to drive the car in this condition and if I did I'd cook the engine :(
While the car has been sitting (about 4 months) I have noticed a puddle of coolant next to the intake directly below the throttle body . I have not found any oil in the coolant reseviour or water on the dipstick.
Does this sound right? I don't have a lot of experiance with Pontiac engines but on every other make I've worked on, the water jacket does not run anywhere near the intake manifold. Any help or info I get would be greatly appreciated.:)

Just do a search on here and you'll find lots of info about the LIM.
And yes the manifold can leak coolant either internally or externally. Even some older Vee engines of the past can do the same.

Thank you for the reply. I have discovered without a doubt that the LIM needs replacing. Does anyone know of a good manufacturer to go with for the replacement?
