the PCV is number 2.. I haven't done it in a while, but one pulls way more vacuum than the other. Pull one off at a time and which ever sucks more is the one to use!
Also, make sure you car is running when you put it in.. When i was 16 no one told me it had to be running soo i filled the manifold with 3/4 can on my explorer and trashed the starter!!
GL and enjoy the smoke SHOw!
