That drawing you sent me is not correct, specifically, it's not complete.  If 
you look at the back of the valve cover, there is a PCV pipe below and to the 
drivers side of the solid pipe in the back of the valve cover.  It goes from 
the valve cover to the 8ball at the top of the block.  At the 8 ball, you have 
4 portals for PCV.  1 goes to the IM with ck valve, 1 goes to the internal 
solid pipe that travels to the turbo inlet with the variable pressure valve, 1 
goes to the crankcase, and 1 goes to the valve cover.

IMO, I would delete the variable breather valve, and run the breather to the 
top of the valve cover, and the ck valve replaced with a PCV valve out of the 
twin turbo supra.  This is a variable valve by definition, the one in the audi 
is not.  I would locate the breather in the center of the valve cover to 
avoid the problem of oil sloshing.

Speaking of oil sloshing, if you gander at what the neon boys are going thru, 
they have the exact same problem, like comparing the double walled 5k valve 
cover with the 20vt.  On the new DOHC neon, the PCV was moved to the back end 
of the valve cover, ala 20vt/v8.  Riddle:  However, since the neon is a 
transverse motor, the oil gets tossed into the vent tube...  On hard right turns!  
The trick fix is to get the SOHC early neon valve cover which has the PCV...  In 
the top center of the valve cover.  And just like here, the 'easy' fix, is to 
use a catch can.

Sound familiar?

Take a look at the car dave, not that drawing.
