To control crankcase ventilation, Bob at Brit-Tek recommended the
following to me: take a length of appropriate-size hose, and run it
from the riser on the engine side cover straight down so that it
terminates in the airstream below the car. Then cut off the end of
the hose on a slant, so the opening in the end of the hose is
oval-shaped, and facing towards the rear of the car. At driving
speed, this will pull the gases out of the crankcase. I knew exactly
what Bob was talking about, because this is the same setup we have to
draw off gas fumes on our T-34 aircraft at work. Lousy ASCII art
follows:

Hope this helps,
