Valve cover gasket leaking.
Did you use black silicone when you put the new gasket on and check to see if the gasket is sitting properly?....it seems you dont really know a couple things.....

You aren't supposed to use silicone. If installed correctly, just the gasket is needed. I have never and will never use the silicone. It causes a mess. Honda/acura never used silicone when installing these gaskets from the factory.
Well if you use the silicone right it wont cause a mess...i use it to make sure i wont have any leaks and it stays there.
