1997 Saturn Sc2 high pressure cam cover oil leak!?

I have a 1997 Saturn Sc2 with a 1.9 ltr dual overhead cam engine. When I bought the vehicle, it came with a nasty overused cam cover gasket and was leaking oil through the gasket, so we thought that the gasket was the cause. We then replaced the gasket but even then oil still continued to seep under the cover. We figured this must be a result of high pressure under the cam cover. We proceeded to lift the PCV valve to find the cam cover blowing air like a shop-vac in reverse, indicating a huge unnecessary amount of pressure under the cam cover. We feel as if this could be an issue with a cracked head or some malfunction of the head gasket, but are not quite sure. Please help.
