HELP!! How to fix this??

I'm thinking it's a PCV line or something, but I don't have the faintest idea what to ask for if I have to get the thing from a parts house. Is there a way to fix this at home?
.....now you have a choice.......get lots of hose and brass Ts and make your own setup........get a new hose from the dealer.........$$$$$ .......or covert to a LS6 valley cover which eliminates the whole PCV hose setup......less $$$$...........when mine crapped out...........i picked LS6 VC !!!!
