Good luck!

I'll bet it'* leaking out of the same gasket that I recently replaced. The little rectangular intake manifold water jacket cross-over cover plate. You would be wise to change out your throttle body gasket at the same time. It'* an easy job but takes time because you will also have to remove the exhaust cross-over pipe to get at the bolts. But this can be a blessing in disguise if you want to install a new set of headers at the same time.

yea I had found some coolent in the TB when I replaced my TB gasket. I had the car apart for a few days and thought OH **it there is coolent in the engine!! Turnes out everything is fine. Change that TB gasket and check the oil. THe TB gasket is like $11 and some odd change from GM. It is a GM only part I have the part number but that is for a N/A Series I

In case some miss the point here, coolant is supposed to travel from the lower intake, up through the upper intake or supercharger, through the TB, and back down. It'* normal to see coolant when pulling the TB, and I'd freak if I didn't see it.

Is that the technical term?!!?

I know what you mean about seeing coolant stains inside the supercharger inlet when you remove the throttle body. Sure, the coolant naturally flows as Will has stated, but the gasket is a weak point and unless you coat both sides with silicone ( just a light smear) you stand a good risk of leakage that could eventually get bad enough to do serious damage. Thank good GM design for making it leak on both sides, so you get some advance visual warning.
My guess is that the supercharger vacuum at the entrance is very high and tends to draw pressurized coolant thru the unsealed gasket in very small amounts that only progress worse.

that wasnt the only thing loose. the supercharger had a few loose bolts too and the gasket wasnt sealed down on it either
