You need to re-read the last section of my writeup. I am not blocking off the pipes coming off of the exhaust valve cover at the back of the engine! Those remain completely functional and that is where the gases are drawn out of in my design. The two pipes at the front of the engine where the air enters are still used as the intake section of the PCV system.
: The stock OEM arrangement has a breather pipe off the FRONT end of each intake valve cover running to the turbo intake tube. (These are the one Ash says to bypass to the exhaust) Then there are the two more at the BACK of the drivers side only intake valve cover. (These are to be blocked off and existing PCV holes plugged) Now the idea used in SCC they continue to use this set up but simply relocate the connection to the valve cover to a more sensable place. This seems like the best set up since you still use both systems. The front "pre-turbo" PCV tube "sucks" under boost or vac, and the rear "sucks" only under vac safegarded by the check valves. So, if I understand correctly, Ash's idea does not use the two pick up points at the back of the DS intake valve cover. You will drop from 4 PCV pick up points to only two.
: Now here is the question, why is it better to only use 1/2 the OEM system? The more vacuum in the crankcase the better, why use only 1/2? The method used in SCC seems to make much more sense to me. If anything, leave the front PCV's connected to the turbo intake as is, and simply connect the hose from the PCV valves to the AIV points on the exhaust and block off the two pick up points at the back of the driver's side valve cover. I think it's better to use all 4 pick up points as they did in SCC. : Or if you are determined to do something different, run the line from the PCV valves to the AIV pick ups and block the tubes on the DS valve covers.
