Coolant leak on top of engine

[WisdoM]

this week I noticed a coolant smell after driving...popped the hood and didnt see anything dripping or steaming but the res was almost empty. the next day I looked into it a lil further and found coolant on top of my lower intake pooled a bit in the recesses around the injectors... I retourqed the intake bolts and a couple were loose...Im still having coolant show up on the intake, its never over heated or even had a puddle on the ground so I'm guessing its the lower intake gasket? I checked the heater and rad hose but they are dry and have no signs of leaks. any other thoughts on what to check before I tear it apart?

btw its the truck in my sig

Look into the intake manifold gaskets. My antifreeze was disappearing, but not any major puddles, etc. It wound up being a crack in the intake manifold gasket (they are plastic) and it would piss out of there very slowly. Where I have seen them leak most often (also where mine was) is drivers side, all the way up front.

Looks like this to me. If it's on the driver side near the firewall....

Sorry I didnt look close enough. that pic I posted was not right at all. I am doing the heads this week. I will keep an eye out while I am pulling it apart and let you know if i find it.

Im almost thinking its apart of the now nonexistent a/c system??. Other than that plug worrying me the truck runs better than ever...smooth idle and acceleration and no oil or coolant leaks
