CCV System???

I'm going to be putting a new valve cover gasket on and was wonder if the ccv or any other tubes coming from the valve cover has filters are require certain maintenance?

One of the hoses connects to your air filter. If theres no oil getting on the air filter and you don't have any vaccum leaks I would assume they're in good shape. It wouldnt hurt to inspect them and make sure theres no oil build up though.
