'97 Chrysler T&C LX, 3.8L I want to replace the PCV valve. I live midway between two Chrysler dealers. I called the parts department at one and they charge . I called the other and they charge . I called three independent parts places and they were all . Is there a downside to using an aftermarket PCV valve? I know that dealers always charge more, but 5x-6x more? Why?
