you are correct. the small line in the back of the valve cover is your pcv. the green highlighted line goes to your air box. if you dont want to get a whole new assembly, then just cut the broken area out and add a peice of rubber hose to replace it. not as clean looking, but does the job. like i suggested, go to the junk yard and get a new assembly. it takes a couple minutes to replace the entire thing, and will give you newer lines all around.
