The driver side cam cover removal requires a few steps for removal. You first need to remove the air cleaner assembly. Check out the rubber hose connection on it's underside, passenger side. Then remove spark plug wires at the plugs, and move aside or remove. Two fuel lines cross this cover, so you will need to remove one end on each. I removed the forward one at the fuel distributor end, and the other at the firewall by the power brake. Use metric "flare nut" wrenches and keep a towel under to catch some fuel. You might need to remove the vac hose at the power brake, not sure. Remove any rubber hoses from the cover. Look at the hose that runs along the inside of the cover and connects to the injector housings. I removed the hose ends at the 4 injectors so the cover was clear. No fuel here.

There are bolts on the cover. Remove and take off the cover. The oiler tube end that was referred to is on top of the cam. An aluminum hose is between them. I recommend that you purchase replacements, as well as a new cover gasket and cover bolt seals. You should be able to re-use the aluminum tube if you don't bend it. Be carefull when you pry out the plastic connections and check for plastic pieces, as these get brittle. Gentle taps with a rubber mallet allow you to fully seat the new ones (after attached to the tube). These parts are all available from online parts sources, and are not expensive. Be sure to torque the bolts to spec when reassembling the cover. Too much or too little and they could leak. Good luck, I hope that fixes your problem.
