I am sorry that you have not been helped yet. I just came online and saw your question.
It usually helps to see the leak, so if possible if you have it apart to see the cam gear, can you take a photo and upload it here using the paperclip icon on your reply bar.
I havent seen one leak from there before, but if I can see what it looks like, I should be able to diagnose it for you
Ok, sounds good. Also check to see if there is front to rear movement of the camshaft itself
There isnt any where else there for it to leak unless there is some hairline crack on the back side of the cam allowing oil to seep thru the bolt holes, which I have never seen in my 30 plus yrs of auto repair.
It has to be coming from the cam seal.
Sounds good and let me know how it goes.
