Question for the group. On the top of the passenger side valve cover in the back are the pcv valves. Has anyone on here had them fail?

If so, assuming they are replaceable? The lr3 is a snap to replace the single valve, but have not explored how to replace these valves on the 5.0 engine and can’t find documentation. Anyone?

Reason for the question is I have a minor oil leak on my valve cover. 120k on odometer and feel as though it’s time to replace these valves.
