HELP! Potential Gasket Leak?

[MidnightsPaleGlow]

Hey all, I noticed a problem with my 93 S10 Blazer 4.3 Vortec recently. On the front of the engine block, near the base of the intake manifold and the 1-3-5 cylinder head, I noticed a slight antifreeze leak (a tiny stream of green running down the front of the block) and am starting to fear that something is definitely going wrong. The thing hasn't overheated on me, as the temperature gauge is still reading within normal operating range (between 208 and 215), but I also noticed the idle speed has been slightly high as well, the MIL lamp came on and gave me the trouble code for the Idle Air Control Valve, I replaced that and the light still comes on. I'm starting to fear that it may have some kind of gasket leak. Any help is greatly appreciated.

Before you go through all of the work replacing that head gasket run some tests and make sure that coolant isn't just being blown back by the fan from another leak.

I know today I quickly ran my finger along the inside of the valve cover on the 1-3-5 side and didn't come out with any frothiness when I removed my finger (I didn't have the time to remove the valve cover, so I unscrewed the oil input and felt around the hole there, my finger didn't have any frothy stuff on it). I also pulled the spark plugs on that side and didn't find any green on them, tomorrow I'm definitely gonna pull the valve cover from that side to get a better look.
