You are 100 % incorrect. I believe you are talking about the transmission vent. The crank case vents out the rocker boxes. Do you think aswracing who is Hammer Peformance wouldn't know that.
As the pistons go up and down they create pressure in the crank case. To relieve this pressure its vented to the rocker boxes where it is metered out through the umbrella valves in the rocker boxes. They are designed to let air out but not lest it suck air back in.
