Give some data on your car? You have to lift the motor or drop the tranny. Either way it's a lot of work. Most prefer to put the car on a lift, drop the subframe and tranny. If the rest of the car is not in good shape it may not be worth it. Only do it if you plan to keep it 2+ years.

Oil leaks are hard to trace down somethimes. I had a little plate leaking on our S70 once, cost $8 for the gaskets and took 40 minutes to fix. Wipe and run, keep doing that till you pinpoint the leak.

Make sure your PCV is serviced to avoid a RMS leak.

There is no valve cover gasket on these heads. Its metal to metal with sealant in between. There are seals on each end of the cams, two on the front and two on the back. One of which is inside the distributor and most likely the issue. Buy the rear cam seals, replace them both, clean it up like rspi said and keep an eye on it.

Ahh, I see...wrong name. The engine takes 5 of those, they are seals around the spark plug holes. The rest of the valve cover uses sealant. The cams are line bored so if there was a gasket in there the cams would flop around.
