[QUOTE="FireRed04Vert, post: 2715121, member: 21229"] The only thing you're "breathing" is the crankcase...not the combustion process. But I would REALLY reconsider your choice of doing this on a street car. Putting vacuum to the crankcase does a couple of things that are beneficial to your car. First, it can put a slight vacuum on the crankcase which is very good for performance, ring seal, and oil control. (look at a vacupan system some time) 2nd, it will positively vent your crankcase of unwanted byproducts in the crankcase. Every car develops moisture in the crankcase. Once your oil reaches 212 degrees, this moisture turns to vapor and the PCV pulls it from the crankcase. Breathers don't do a very good job of this. Even the very old systems (early 60's) would put a draft tube in the air stream under the car to aid this. If you leave the moisture in the crankcase, among other nasty things like a milkshake, it will turn to an acid and ruin your bearing surfaces and pit your cylinder walls and cam shafts. Not a good feature!! I can't see any benefit to remove the PCV system. If you are from a humid climate, drive your car for a few hundred miles this way then pull your oil cap or breather off. Look underneath it. I will just about guarantee you that you will find evidence of moisture. [/QUOTE]
