Bad valve cover gasket?

Hey guys I was checking my spark plugs today and the plugs and the spark plug socket came out covered in oil is this normal?,I've done some research and I might have a bad valve cover gasket,also while driving it will jump up in revs sometimes while cruising and when it changes gears,also drops revs and seems like it's losing power,any help is appreciated because I'm stumped
 
Do you have oil on the actual threads, or just in the well? It can be pretty easy to see a valve cover leak if you have a pic? Anyway, it's easy to change and cheap, when I changed mine it was snapping in half the rubber was so brittle.

Sounds like you have an auto? If there is oil on the threads, it could be valve stem seals as well.
