LOL, the yellow gunk you see is the cause of the CCV failiure, not the otherway around. They're trying to get your money. + The valve itself rarely "fails", it gets clogged. once it's warm, you can fill it with brake cleaner or degreaser, wait a couple minutes and empty it. Once this is done gently blow the passages with compressed air and it'll be like new. I say gently because, if you go at it full pressure, you will dammage the diaphragme inside.
(You need to remove it from the car before performing what I described above)
