It's probably the seals for the valve cover gaskets. The problem is that the PCV freezes in the winter and the presure under the covers builds till it pops the seals. Not real hard to change them but it's work. I put new cover on because they came with seals, that fixed the leak. While you are at it, install the new PCV kit( 15minutes)

Do a search on PCV ugrade and you'll get the info.

my oil leak from the front was the oil sending unit right beside the crank pulley, 14 dollars and 20 mins later good as new, and i live in canada with -30 temps and my pcv system is fine, my valve covers did leak but that was due to the bolts coming loose, loose enough to turn by finger, tightened up and im leak free (besides my rear axle seals :( )
