i've searched..and the best to my knowlege..nothing is been answered..well, this car is full obd2 swap on an obd0 chassis....the motor is running on obd2 harness..ecu, and all the 9 yards...anyways..that'll be no problem for me...cause i can always convert that using an obd2-obd1 jumper harness...

the question is....there's 2 hoses on the manifold..one for pcv valve..and the other one routes behind the intake manifold..i seen some pics of it..and i don't know where it goes..is important to run that? i don't think it is...and im only running on 1 o2s..the primary..here's the pics of what im talking about..
