pressure builds up in the crankcase as a little blowby seeps past the piston rings. the stock setup takes this positive pressure (along with oil vapor) out of the crankcase and reroutes it back into the intake stream to conform to EPA regulations since venting to the atmosphere is considered harmful to the environment. this oil vapor can cause detonation as mentioned. thats why we use catch cans to trap it. venting the catch can to the atmoshpere is the sure way to take the positive pressure out of the crankcase and make sure none of the vapors make it back into the intake. Actually, you could technically just leave the two ports on the valve cover open, uncapped, but you'd have oil all over you engine bay.
Yes, I was talking about the little filter on the catch can. you need to replace it when it gets saturated in oil because if the pressure can't escape it'll build up in the crankcase and blow your oil seals.

In all seriousness, I've never considered this, nor can I recall hearing it before now. Is the basis of the argument that oil vapor is more prone to autoignition or detonation in the combustion chamber than atomized gasoline?

I ended up getting a 1/2 inch to 3/8 reducer instead of the PCV valve and routed the hose to the catch can. I am still thinking if instead of the filter i should route a hose to the pre-turbo nipple i have on right after the intake filter.
