Oil Won't Go Down on 1997 Saturn SL2

I checked oil and only a drop on tip of stick. Tried to add oil but it won't go down as if full. What could be the problem?

Did you remove the oil filler cap, This is what it looks like,2591066/vehicleId,2347801/initialAction,partProductDetail/store,2854/partType,00146/shopping/partProductDetail.htm The cap is located on top of the valve cover
So the Valve cover is full of oil and its not draining down the passages to the crankcase, Will have to remove the valve cover and see whats clogging the passages, Here's a guide to removing the cover
