The intake plenum has to come off to remove the rear valve cover. You might be able to buy new gaskets but there aren't any in there now. They use liquid gasket sealer. The best sealer is Mopar silicone gasket sealer. There are two to pick from. The black stuff stays a little more rubbery and it absolutely will not bond and seal if there is any film of oil on either of the surfaces. They must be perfectly clean and dry.
The gray stuff gets harder and it will bond through a film of oil. It's still good practice to have both surfaces clean and dry. Don't get carried away with the tightness of the bolts. Hand tight with a small ratchet is sufficient.
