Default Oil leaking on valve cover on oil fill tube.

97 z28 stock valve covers with a oil fill tube. A small amount of oil is leaking on top of the valve cover at the bottom of the oil fill tube. I am guessing its not on tight or the seal is bad? I've never took valve covers off, but it looks really simple, should I take the valve cover off and figure out whats going on?

I've notice my '95 Is doing the same thing. When I bought her the dumbass before me placed a rubber cover over the filler neck instead of an oil cap(which I've now replaced.)
If that wasn't the cause of it, then what is? Good question.

I've got aftermarket valve covers, with the stock cap (no tube) and small amounts of oil trace runs down the valve cover. Comes from the cap & PVC hoses.
