Trularin, that is the type of system I was trying to describe as a closed system.
JP, I will pick you one up. It is just like Trularin described and I was attempting to describe. The part from ford comes as a chrome "breather" that says ford motorsports on it with a nipple. It also comes with a fitting for the air cleaner. Price is a whopping $8.99. If you don't like the look of the hose to the air cleaner you can always get some of the fake AN stainless cover stuff
