Check the valve cover gasket. Look right back where the valve cover meets the head. You could try tightining the valve cover bolts. Get the torque specs and don't over tighten them. If that doesn't help you will probably have to replace the gasket.
Also check the lines coming out of the valve cover. Find the leak and try to trace it to the source.
