Ps2cho's head was lightly skimmed when we did the head recondition, and the surface was pretty slick. I know Ps2cho posted pics of it at the time.
I was also thinking that the oil leak was from the VC, and have done my very best to isolate the area that is leaking, visually, but you just cant see back there. I tried using my HF Borascope which is a great tool, but I just cant get a good view due to the focal length of the camera and clearances.
As it is leaking so profusely(palm size oil patch every time its parked, and smelly burning oil when you drive) I wiped the back of the VC/head junction with a clean paper towel, and can see no fresh oil on it, just dirt.

I was hoping that someone would have a M103 head in their garage so we could see a rear view, in case there is a gallery plug on the back of the head that is leaking.

I would love to think we will not have to pull the head again over the holidays, but I am increasing sure its the headgasket for whatever reason.
