Felpro makes a really great replacement gasket that’s reusable and never leaks. The 4.0 has a ccv rather than a pcv system and I always replace both vents and grommets (and the little tube connecting the rear vent) along with the gasket when I get another Jeep (I have 6 right now).
Rear crankcase orifice vent is dorman# 47057: https://www.amazon.com/dp/B000JZI1U2/ref=cm_sw_r_cp_api_o1AQBb8PJSXPA

Grommets are both dorman# 42344: https://www.amazon.com/dp/B06XS8XYHJ/ref=cm_sw_r_cp_api_K2AQBbMPJ1Z33

The front vent is available in different heights depending on year/model but I think yours is a doorman 47079. In a pinch you can always buy 2 of the orifice ones and drill out the restrictor.
