So I just saw that my valve cover is cracked, so I need to get another from the dealer tomorrow.

The parts guy at the dealer said a plugged ccv or ccv hose could cause excess crank case pressure and that could have cracked the valve cover. Any truth to that?

I've never replaced the ccv but I'm not so sure I want to do it if I don't need to, looks like a pain to do.
