Yea might be worth a shot to look but judging from the pics it doesn't seem to be coming from that area.
It looks as if its coming from above which is why I suggested to him it could just be from his excessive blow by out the breather, however on second look it could be getting blown out the cylinder and leaking out past the gasket due to broken manifold stud not sealing properly, which is why there is also oil on the inside of the manifold.
We both live in Darwin so reputable mechanics are stretched far and thin and I have always done work on my own car due to this, so I wouldn't be able to suggest anyone to take it too for a proper analysis.
