look at the valve covers, some are held in place with 6 bolts some with 3. Do one at a time keeping the work area very clean. Clean valve cover and have clean hands when putting gasket in. Then, just reverse removal process. If you are unsure see a mechanic. I am assuming your problem is oil showing up around the spark plugs.
On the Mazda very simple procedure if you are unclear go to autozone.com they have online manuals or automd.com both are very helpful
