It’s been puzzling me for some time, "Why does the crankcase vent valve point to the manifold (vacuum) side"?
The little restrictor valve within the valve body, you know the one we all clean on a regular basis, is held open by the spring. As crankcase pressure increases and the rocker cover vents via the tube, the pressure acts on the restrictor valve tending to force it closed.
Therefore as crankcase pressure increases the vent valve closes. Stopping the flow.
That seems A** about T*t, to me.
Somebody put me right please.
I'm confused.
