I have read a lot about converting the road draft tube from the side of the block to the back of the valley cover. From the valley cover, the road draft modification is routed thru a pvc valve and into several options to include base of carb or intake. Would this not just route a lot of contamination into the intake? It makes sense to get rid of the mess created by the road draft tube, but not to vent it into the carb or intake manifold. What am I not understanding? This inquiry is not about how to do the modification, but rather why its done this way.
