[V8] V8 CV

[Ed Kellock]

I probably won't be able to add anything technical, but holy crap! that
looks complicated.  All that hardware and more coolant lines to keep it from
freezing?  Sounds like a nightmare just waiting to attack.

Audi's solution to our CV problems are graphically illustrated here: 
www.s4-mtm.com/images/RS4V8-StudyGuide.pdf  for the V8 FSI engine

The crankcase is ventilated through both cylinder heads. The valve covers 
incorporate a large settling space. This space acts as a gravity-type oil 
separator. A fine oil separator is connected to the valve covers by means of

plastic hoses. 

After the blow-by gas has passed through the fine oil separator, the gas
flows 
into the intake manifold downstream of the throttle valve. 

Blow-by gas volume is dependent on engine load and RPM. The fine oil ("oil 
spray") is separated by means of a cyclone separator. 

 Piston ring flutter at very high engine RPMs and low engine load can result
in a 
very high gas-flow rate.   etc., check it out.

Their PCV unit is an add on that you may improvise from.
