It should pop right off. It did on my '02 WJ. My XJ needed a gentle tap with a rawhide mallet. DO NOT pry on the lip of the cover with a screwdriver!

Do you need to replace the gasket when you take the valve cover off? I know you should, and I will at some point but it's like a $40 gasket.

I'd like to take off the cover and clean up the crank case, but I guess I'll just wait until I can afford to buy the replacement gasket.

Make sure you also replace the grommets that hold the valve thingys in the valve cover.

Put on a catch can and then you can still be legal and keep the crap out of your intake. They're cheap to buy and/or easy to make yourself. The WJ has a PCV valve that I put a catch can on AND it has a continuous crank breather to the intake (explian that one!). I plan on putting a catch on that line as well.

Thanks for the info guys

Getting ready to replace the CCV on my 94 and just wanted to to thank everyone for the information. Someone mentioned getting a hold of a Jeep service manual other than the Haynes one...where can you get them I didn't see any listing on Amazon.

Thanks all.

A subscription to alldatadiy.com gives you access to the service manual. The Haynes manual and JeepForum have provided me with answers to all my XJ build questions though. The schematics drawings are nice though.

I replaced my gasket once and thought about replacing the elbows, but they were both clear and just needed a blast of cleaner and some work. Still, I was lost as to how to get these hard plastic pieces out...that's right, they were so dang hard that I assumed they were phenolic plastic or something like that. I would have never thought they were rubber at one point. I tried to pop one off and it chipped just like plastic. Maybe next time I have a leak from the valve cover they will come out. At least now I know what I am in for and can prepare accordingly, thanks a bunch.
