your tube seals are leaking big time, mine did the same thing, they just get old after a while, replace the tube seals, the 4 ruber circle gaskets, they slide right into the underside of the valve cover, and then get a valve cover set, replace the gasket, put some hondabond on the corners of the gasket and where the gasket makes a half circle to cover the cam side, then check that shit later, that should fix your problem.......
