ls1 oil fill breather 
do i need to pull vaccuum from somewhere when deleting the pcv system or can i just run this breather and cap the ports on the valve covers.. This is racecar only and to my understanding during WOT there isnt any vaccuum to pull crankcase pressure anyway...
i plan on running a hose on the back of the valve covers to connect them together and just vent to atmosphere on the pass side with this breather from hawks... Does this sound good??
