Very likely

As others stated, likely the rear main seal. Also, it could be coming from the dipstick tube or oil filter. Especially if you have a clog in the PVC system or a great deal of blow-by (like me). Degreasing the whole thing and trying to verify the leak site is definitely the way to go.

If it is a valve cover gasket, DO NOT get the cheap cork one. Spend the extra bucks and get the molded rubber one. WELL worth it.
Had them order in a NON CORK valve cover gasket for my aluminum valve cover. Just picked it up, it's aluminum. Thoughts?

Ooo, just opened it up. Looks like molded rubber with an aluminum core, so I guess I did get the right one after all.
