When looking a little closer I couldn´t find any oil at the rear intake seal that was finding its way further down at the back of the cylinder head, all dry there.
I wasn´t sure but hope never dies, after I had the intake retorqued it was still leaking. When starting the engine up and let it warm up a bit while inspecting the area with the mirror I saw a drop of oil coming from the lower corner of the head (marked in the pic below).
My thought was that while I was having the engine apart this far I might as well pull the head and have it checked.
Probably had multiple issues, both the intake and the head, although the oil from the intake stayed on the valleypan.
One thing that sucks is that the header needs to be removed to be able to retorque the heads.
