What's wrong with my 2004 Nissan frontier 2.4 4cyl?

I went to change my spark plugs, and before I pulled any out, I found 1 full of oil. The other 3 are dry. Please help.

Replace the valve cover seal and plug seals.  Not hard to do.

The valve cover needs to come off and the spark plug tower seals replaced.
