For an NA, simply re-routing the crank case ports to a catch can and plugging the PCV valve sockets in the intake plenum is enough. For a TT however, all that extra blowby means you have to plug up the stock crank case ports and make a new ones in a better location. Woody75 referenced this post which shows how the valve covers are tapped for an optimal solution:
http://www.twinturbo.net/net/viewmsg.aspx?forum=general&msg_id=1785487 What are we doing? Well...to do the above fix right, you have to pull the plenum and pull the valve cover so you can drill it without dumping metal bits into your valve train, and all that is a PITA. Also, I don't really NEED two vents to feed the two sides of the intake system, I'm just dumping the blowby into a catch can anyway so a single vent should be just fine (I hope). So...well, we're not done with it yet, so wait until Chapter 14, I'll have pics and full details in there.
