It uses a form-in-place gasket that should be reusable if it stays in one piece.
All you need to do is skin another coat of Permatex or similar RTV sealant, fill
in any gaps or cracks, and put it back. If the gasket material comes off or is
in real bad shape you will have to lay down another bead. Jeep sells the gasket
material but I've used the stuff from NAPA with good results. Just follow the
directions and make sure the surfaces are clean of oil (wipe with alcohol).
The nuts/studs only go down to 75 in.lbs. Make sure it's an even bead otherwise
you will get leaks. (that's the tricky part)

Re: Clogged PCV tube
No, excessive crankcase pressures are not an urban legend. It usually goes
along the lines of a leaking rear main seal, which you fix, then a week
later the front crank seal, which you fix, then a week after that, the valve
cover gasket, which you fix, but by now you realize that the clogged PCV is
the root cause of all of your problems, and you fix that, too. Ask me how I
know.
