If the oil is leaking from the top of the engine, it is most likely a bad valve cover gasket. Or it could just be loose bolts around the valve cover. There is no 2005 626, just a 2005 Mazda 6. The image below is the Valve Cover of a 2005 Mazda 6, four cylinder engine, with the bolts numbered in the order that they should be tightened.
If you are comfortable with doing it, you will need to remove that cover, scrape out all of the old gasket and grommet pieces, and then install a new gasket and grommets (the little rubber circles that go around the spark plug holes). Then put a little bit of gasket sealer on the gasket, put the cover back on, and tighten the bolts in the order shown in the image.
If you pay a mechanic to do the job, they probably should not charge for more than an hour of labor ($80.00) plus the cost of the gaskets.
