I've seen PCV valves on other cars that bolt in with a replaceable gasket.
Makes it very easy to maintain and replace. Jeep could learn a lesson

When my intake hose (the front one) got plugged up by a leaf in the
airbox, the damned thing didn't leak just one place - it blew oil from
every seam and seal on the engine! Even when I cleared it I wound up
replacing both the front and rear main seals - but they were likely
the original 1988 seals and hard as a rock, so they were due anyway.
