Default 1998 Suburban 7.4 coolant leak, how screwed am I?

I bought a 98 Suburban for dirt cheap, everything seemed in mint shape, however when I got home I noticed a very slow leak from right below the thermostat. How bad is it?

When I bought it I figured it was the intake manifold gasket cause 7.4.... I don't know how well you can tell from the pictures but it seems like there's actually a hole in the intake manifold itself?

Lift the wiring harness out of the way for a better look/pic.

I'm surprised you say slow leak; looks like a pretty good sized hole that would pass alot of coolant

Clean all that residue off so you can see better.

My guess is it's JB welded on the inside.

Well, if there is a hole, I guess I would be shopping for a new lower intake manifold...
