Spark Plug Question

I pulled my spark plugs today after someone told me I may be experiencing a slight engine miss fire. Well, I pulled all plugs and found one plug caked with, what looks to be, baked motor oil deposits. Can anyone explain what is going on internally that could cause this? This is a picture of the Right Bank front #1 plug. Thanks

if its caked with oil then its the pcv system most likely.. either directly from the pcv itself or the fresh air return line reverting.
