The famous "Savage Plug Leak" (assuming that we are talking about the same thing) comes from under the head cover and right over the right front head nut. In the opening to the left of the header pipe when looking from the front.
When it happened on ours it was after the dealer's "1000 mile" check-up, and what is even better when I opened my spouse's up the plug wasn't all the way seated in the head anyway. They have to remove the plug to torque the head nut during the initial service.
Here is a shot of when I fixed hers and it also shows the additional silicone rubber that I used on the plug.
