I don't know for sure. But, gut instinct, I doubt this makes any significant contribution to cooling. Sounds more like a DPO bodge to get rid of the PCV valve, no more. For any effective air cooling there would need to be a continuous stream of cool air entering the valve cover, which would then require a separate outlet for the warmed air to come out again. With this vent pipe, the only flow along it will be a (hopefully slow) passage of blowby gases coming out of the valve cover.
