Default Possible coolant leak at WP casting & Hard line?

I just pulled my Exhaust manifold and as I was getting ready to install the header, I noticed drops of coolant seeping from where the hard line under the manifold connects to the water pump casting (I did have to move it a bit to get at the far nut nearest the firewall).

It was only a few drops and appears to have stopped, but I've never had the WP or casting off and am not sure how the hard line seals into the WP/casting.

Do you guys think I might have fucked something up and need to pull the casting off? If I have to, I'd rather do it now than install the header and fnd a major leak when the radiator builds up pressure.

Theres an o-ring in there where the two meet.

That makes me feel much better and explains why it would seep coolant after moving the hard line. I'll just install the header and I suspect it will be fine.

If not, it will still be easy to pull the casting now that the AC is out of the car.

hard line press fits and seals with an o-ring.
be sure that the hard line is fixed to the engine with a bracket secured to one of the exh mani studs, otherwise it's likely to seperate while driving. (it's happened to me)
