Default Coolant leaking back on engine

Gentleman,
I though my S10 Blazer (1996 V6 4WD) had a radiator problem yesterday, white steam from under hood when slowing and stopped.

On inspection the radiator and hoses are OK, looking under the vehicle from behind drivers side tire, with engine idling I could see a thin but steady stream of coolant coming down from right above the back corner of the oil pan area.

Cannot see exactly where it's coming from yet, any ideas? I searched some threads and found one talking about freeze plug(s) leaking but it's been nothing but hot around here!

This is my first post...be gentle

could be the intake also. the engine is leaning back inside the truck a little bit so any antifreeze on top of the engine will roll out the back. try looking all around the engine on top and see if you see any wet areas

I would suspect the lower intake manifold gaskets have failed.

Looking down on top at the back of the engine I see no wetness, I'll try a mirror down behind to look for the leak somewhere at the manifold gasket.
Thanks guys!
