Re: PCV VALVE QUESTION!
I did the slashcut method and for some reason I receive pressure instead of vacuum. I thought I placed it in a good area of the exhaust system but obviously not.
I would love to see pics of someones slashcut setup. Post em up!

-and the intake side for vacume is recomneded because it doesn't have enormous amounts of vacume. The whole idea is to release positive crank charge not suck what little amount of oil we have in there out.
One question i always had was when people put breather filters on their valve cover and also a catch can. to me it seems if your running a catch can no matter where from the whole idea is create a vacume system, doesn't the breather release that vac.?

Re: PCV VALVE QUESTION!
There are pros and cons to various methods of routing your PCV setup.
You can run a line from the pre-turbo intake for vaccuum but then you risk sucking oil vapors directly into your turbo and detonation sucks. You better make sure that you have a good baffled catch can and I'd throw some steel wool in there to catch as much oil vapor as you can.
Running to a slashcut in your exhaust is the best option IMO, who cares if a little extra oil vapor comes out of your tailpipe? But I do live in Wisconsin where emissions tests don't exist. God I would hate to live in California.
Or you can run the setup like mine, which is just a breather filter on the valve cover and I run a hollow PCV-size fitting directly to a catch can. It might not evacuate the crankcase as good as a setup that has a vaccuum source powering it, but it has been working fine for me for quite a while.
