to replace the valve cover gasket from the rear you have to remove the intake plenum. You have to remove the throttle body from the intake plenum and disconnect all vacuum hoses from the manifold. If you pay for that job, it is about $400.00 labor. I did it myself with care on a Saturday. At the same time, I replaced all intake plenum and throttle body gaskets, vacuum hoses, and PCV.
