Lower CCV hose is easy to find, it is the hose that connects to the dipstick at the base just before it drops into the crankcase. Follow the hose back toward the front of the car, you will then find the bottom of the CCV. Feel with your hands, if there is oil all over the hose, likely it is torn/collapsed at the base of the CCV.
Replacement hose is about $15 as I recall? I think you can also use 3/8" fuel line as well if you are in a bind.
