Well actually I believe the valve cover gasket only gets blown out when the ccv freezes so you should be okay with that.
Depending on how long of trips you take when you drive your car, oil and moisture build up in the hoses can occur. My ccv and hoses were nasty when I replaced mine and it wasn't leaking too bad, but I also live in Minnesota and made short trips in the winter. Oh and when you do decide to replace the ccv replace all the hoses with it as well. At this point just keep an eye on it and you should be okay.
