Same issues and I had two other leaks besides the valve covers.
The oil pressure switch in the front of the manifold was leaking out the top and onto the top of the engine then down the passenger side. You should be able to easily see this one.
My biggest problem was the PCV and another breather hose in the back top side of the engine. I basically had to replace anything made of rubber back there. I wouldn't even suggest trying to take it apart until you have all the new hoses in hand. Everything rubber I touched back there basically disintegrated when I tried to remove it.
