Is the qusetion how to ? Cost and time? To remove and replace the gaskets will take you aprox 6 hrs. You must remove the plentum and replace that gasket as well. I strongly sugest Plugs & wires at the same time. the rear on is a bugger but have some patience. The job if you do it yourself will cost around $140 wit aftermarket parts. Use only nipendanso lugs.
To remove the wiring harness for a 1998 Toyota Avalon during a valve cover gasket repair, first, disconnect the negative battery terminal to ensure safety. Carefully unclip the wiring harness from its mounting points, making note of any connectors or brackets that need to be removed. Gently disconnect the electrical connectors from the ignition coils and any other components attached to the harness, ensuring not to pull on the wires directly. Once all connections are free, you can safely move the wiring harness aside to access the valve cover.

An oil leak there is probably a valve cover gasket leaking. it would not require head gasket replacment. Try tightning the bolts on the valve cover. If that does not work then replace the valve cover gasket. Yes it could be the head gasket as there are oil passages in the head and i have heard that head gasket on saturns are prone to failure,look around the valve cover for sings of a leak hopfully that's all it is because replacing the head gasket is costly on th 1.9 sohc
