AntiFreeze on the Intake?

So again where did it come from?

Pressure test, dye might show a rad leak that is spraying a small jet of coolant that ends up in that location?

I used dye on an AC leak, saved me from taking the dash out of my minivan!

I'd say it's either coming from the intake gasket or maybe the thermostat housing? Should be pretty easy to figure out. Hell, wad up some paper towels and let those tell you where the leak is originating.
