Default Green liquid in throttle body

When i was working on my coupler change earlier i discovered a green liquid seaping out of the throttle body. i havent taken the supercharger off yet but i know there is some in there too. what can this mean can it possibly be antifreeze

I'm not sure about the Series I, but on a Series II it would be a gasket leak between the supercharger and the throttle body.

I'm sure its very similar situation, sounds like a leaky gasket. If it was an NA engine I would be more worried.

Are you running low on coolant?

It likely hasn't caused any major damage, but fix the gasket immediately. Once all done you might want to do a top engine clean using GM Cleens or similar pruduct, be sure to do this in a somwhat remote location because it puts out a lot of smoke. You might also want to do an oil change.

Good luck!
