Claus/Dave
I just picked up a spare valve cover from storage, and Dave, I'll share  that 
the port below and to the DS of the internal turbo breather pipe is the PCV  
vent for the valve cover.  It's the one that comes out of the valve cover  and 
has a 90 degree elbow.  I find it very interesting that the external  port is 
much larger than the internal port.  The internal port looks to  have a lot 
of extra meat for drilling a larger bore up to the size of the pipe  at the 
exit of the valve cover.  I'm convinced this was designed to  accommodate boring 
of the internal port to match the head demands of PCV.
 
That said, it sits in the back of the head, without baffle, windage,  
perforation box, or diverter, just waiting for a hard launch.
 
There is no question in my mind that on hard launch, it's not the block  
sloshing that creates the problem, it's the head sloshing that creates the  
problem.
 
Dave and Claus, I will send you detailed pics of the AAN valve cover so you  
can looksee for yourself.
 
Best Regards to a beaten horse.
