How to change the valve cover gasket on a jeep grand cherokee?

i have a 1996 jeep grand cherokee limited. it is an 8 cylinder. i was just wondering if when changing the valve cover gasket do you change 2 the right and left or is it just one? the left side has hoses attached to it so i am assuming thats the one to change. the right side has an electrical looking attachment on it and thats all. Are both gaskets?How to change the valve cover gasket on a jeep grand cherokee?Both covers will have gaskets. You cannot see the gaskets. They will be between the valve covers and the heads, on the UNDERSIDE of the valve covers.
