Iirc high speed track with lots of lateral G's.
I believe Crawford at one point recommended disconnection in these situations. Though its been awhile since I researched this and I may just be talking from my bunger.

disconnect from the block and heads or disconnect from the intake tract?

hmmm. I have heard online that you can push oil out of the heads on high lateral g long turns. but I personally don't know how likely or true it is. also, to my eye, if you look at the stock setup the same thing would occur so I don't see how disconnecting the heads part would help
daaaaaaaaang, four pages and we are still discussing/wondering? well let me put the nail in the coffin on this one. With everything that everyone has been saying in reference to "well it didnt come from the factory like that for a reason" yes, you are right. The way cars are built and constructed they have to meet emission requirements ALL across the board and build them ALL the same (thats how an assembly line works to maximize profits). well we cant "dump" anything into the atmosphere because gore swears it tears up the ozone layer. That's why, stock, these cars come with all the fancy performance restricting parts that if you change them (expecially in california) you run the risk of failing emissions testing. either mechanical (cats, O2 sensors, changing the tune) or visual (evap system). all those things keep everything environmentally friendly but kills performance. so when it comes to catch cans/venturis/aos WHATEVER those are in reference to the evaporative emission control system (evap). the way the stock system works is that is routes all of the oil precipitants or moisture from the block and heads back into the intake tract for it to burn. Some of it is valved and some of it is not(problem). the purpose of the valves is to prevent positive boost pressure being pushed into the motor thus deterring the chance of positive crankcase pressure. so far no advantages right? as time goes on you will start seeing things like this: 
in some of the evap lines due to moisture in the oil or things like this: 
and 
with the vapors building up or actual oil being pushed back through the intake which causes oil consumption and making the intercooler less efficient. it also coats sensors and creates buildup on the injectors and valves.
so whats the relief? well one of the worst things out there i have seen in the GS AOS. why? because this:http://forums.nasioc.com/forums/showthread.php?t=2228499 It sounds good the way GS sells it but common! its all marketing and from a mechanical standpoint its a horrible design. I cant believe how something like that can cost so much and THEN be ineffective.
option 2: the crawford AOS. Again on paper it sounds good, but my OMG its expensive and do you really need coolant running through it? not only that moisture builds up in the oil and it really doesnt get "caught" or separated and the crawford AOS STILL runs it back into the intake so for me, no thanks.
the BEST option, #3: this: http://www.elementtuning.com/images/products/Element Competition Catch Can.jpg or this: https://www.himni-racing.com/images/catch can rx8.jpg this is what bip power hondas and v8's use. yes, you might have to deal with possible fumes and extra maintenance but that is the sacrifice when it comes to modifying cars and going into more higher performance.
if your catch can system is working right you'll see things like this:
and this: 
now do you really want that crap being recirc into your expensive built motor? or just avoiding a rebuild all together? the crawford markets their product well when it comes to "low maintenance" and looking good in theory but to pay triple for that? or even build your own catch can for less? no thanks. catch cans is a simple yet good design that has been used for YEARS thats PROVEN and they come in all sizes and designs and have the possibility to be cheap, expensive, customizable, WHATEVER...
and to the person who that something about lateral g's and what not; garbage. there is a reason why the oil pan and valve covers are baffled and there are oil galleys positioned how they are. how do you think baja trucks, and drag cars deal with oil starvation? autox cars run the lowest risk and even still there are better oil pans that we can purchase if you want peace of mind. as long as the oil pump can still suck up oil, its all good.
and lastly, thanks JJ for putting this topic on facebook. I wouldnt have been able to give my input if it wasnt for that...

Thought I would share this.

^ ??? LOL Pink?
I'm sure the smell is due to the E85 your running.

First dump it looked like dark piss water. Been kinda pinkish since.
Ethanol definitely makes the alcohol smell.
