"looks like you got the leak"
Yup that ol' ECOTEC has the lower intake manifold leak...
BTW, the links to images 4 5 & 6 all link to image 3.
As for the problem, who knows. Doesnt look like the headgasket to me, it looks like the oil is actually coming from somewhere lower down on the engine. Bring it in to the dealership, and check the oil often; you don't want to drive anywhere with no oil in the pan :P
