This PCV Replacement kit comes included with all components needed to swap out your old cracked/leaky diaphragm with a new one without replacing the entire Valve cover or even having to remove it. The most common issue in the past was the old brittle cap breaking when diy'ers would remove it from the valve cover. Our kit includes a replacement cap so that your install job can be worry free.
