[urq] Too much Crankcase ventalation?

I think there are some misunderstandings of how PCV works, and the risks  and 
benefits of a variable PCV valve closed loop system.  If I were looking  to 
modify PCV to be properly routed, the nicely designed ball valve used in the  
toyota supra turbos is where I'd start my search.  For a good introduction  
into how that valve works and some of the issues, take a gander thru this  pdf...

I used this information as a guideline for PCV reroute and modification on  
my supercharger addition to my landcruiser

Claus,
This is the same experience I've had.  Mine is a '93 UrS4 with an  AAN, and 
runs in the lower 12 second range as well.  Upon launch, oil  goes 
everywhere... typically 1/2 quart pushed out the breather on  each run.  The car isn't 
geared appropriately for the 1/4 mile, so I end  up going through the traps at 
over 8000 rpm.
 
During daily use, this is not ever an issue... but very annoying during a  
hard launch on the street or track.
