90degree twist ccv valves

hey, bought an xj a few days ago and I need to replace both ccv valves the front is broken and the rear is gummed all to hell. I have found many write ups talking about push in valves that look to just pop into a rubber grommet in a hole in the valvecover. My ccv valves are 90 degree twist type deals and I cant find replacements for them. am I missing something? did the grommet supersede the twist stile? anybody got a part number?

Year on that XJ?

If you own a Renix Jeep, you'll want to check this out.

There are no valves in the system.

96 ZJ Laredo, 4.0, 242, 230K
95 ZJ Limited, 4.0, 242, 140K
98 XJ Sport, 4.0, 231, 140K
All work well

the jeep its self is a 96 but I am now pretty sure sombody swapped the engine at some point to a 92-94 i think. It has a twist lock style oil fill cap and ccv elbows. I called a local jeep dealer and got a good intelligent parts guy on the phone, he knew what I was talking about but couldnt look it up in the computer. I decided I will just go pull a newer valve cover from the local picknpull on my day off and use the newer easier to come by ccv system. On first inspection the jeep looked decent with a few minor odds and ends but now I am not sure how deep I am going to have to go into it.

can anyone tell me what I the major differences are in the early 90s and the 96 4.0s? in other words what else am I going to have trouble tracking down?
