Now the only reason this makes sense is the valve closes itself under max boost from eliminating itself from pulling oil through the system. so if this is the case, and I may be wrong. Then why not throw a breather on one valve cover like gassers have and a pcv type setup on the opposing valve cover so that you are making a "FULL LOOP" in suction?? Everything i have come to understand is that when these valves on our diesels go bad they seem to consume allot of oil. Well that would make sense if they are stuck wide open,"no place to suck from but the crank case at all pressure's". so if you had a draw through system then an engine would be more efficient and not be deluded to positive pressures at anytime. One could bypass the cdr entirely off of a valve cover and then run a breather on the other and no matter what boost pressure you consume oil will become stagnant without the need of being "sucked" out because of no restricted flow of re-lease. A new engine would not be accustomed to substantial amounts of blow-by because of the ring tolerances. However an older engine with worn wall's and or rings would benifit mostly from something of this nature. And with a true positive evacuation these engines may just improve life span.
