My misunderstanding. When I removed the small pipe flange, oil leaked out, or so I thought. I had assumed it was a breather for the head, it being connected to a valve, which I thought was a pcv valve, then on to the air box. I took it off again, it is that thin black lacquer 'stuff, NOT oil as I assumed. I smell exhaust. I now understand it is connected to the exhaust stream.
What I don't understand is what the heck is that black stuff, a combination of water vapor/oil?
