David Vizard details exhaust extraction for ventilating the crankcase. It
uses the flow of exhaust gasses past a tube inserted just after the header
and requires an anti-backfire valve to prevent explosions, as well as a free
flowing exhaust system to be effective.
He has a name for the idea, but I can't remember what it is.

I enjoy long walks. Especially when they are taken by people who annoy me.
