It's been advised not to eliminate the PCV system as it does serve a function other than venting.
Bull Shit.......
The PCV is terrible about putting crap into the turbo, and intercooler.
Although it will pull a slight vaccuum, it is hardly worth the downside of gumming up everything in the induction system.
I either run the crank case vent into the exhaust using one of the many available exhaust evac kits, or just a couple of long hoses down past the bellhousing, with some stainess steel wool stuck up inside to keep mud dobbers out.
The Evac set-up is best, as it will pull a good vaccuum on the crank case during full throttle, and help the rings seal.
I might even have a couple of the special check valves around here, they are your if you want them, as I found some high $$ military ones out at Kelly when they were shutting down.
The best, is to run a vaccuum pump, but that is normally just used on all out race cars.
I used to supply crankcase vaccuum pumps to an aircraft company on the west coast, that were far superior to the automotive ones that race shops sell, as they were miniature roots style blowers, where as the automotive ones are vane pumps.
They had failures withy the race car stuff, but the roots would never fail, even when they tested the things to 18,000 rpm.
