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!

Well **** if I know. I ain't there and it ain't my car. Plus, the cats knocked my crystal ball off on the floor and broke it and yall all know how tight money is with us. I ain't got a new one yet. Did you see where I said it might "not" be coolant? It could be oil. I haven't seen where he verified it 100%. Oil "right there" makes much more sense, because it could migrate up the bolts and pool right where it is.
