Examine the top lip of the head for any nicks or dents that might allow oil through. If you find any maybe some sort of hard filler like JB Weld would fix it. But apply it cleanly, you don't want pieces in your engine. If you torque a valve cover bolt down too tightly you will pinch the edge of the valve cover. This could cause a middle section to bow upwards. Also whenever you replace your gaskets make sure both surfaces are clean, clean CLEAN!
