I think you may be on to something. I also have a check valve installed in a PCV side catch can. It captures a fair amount of blowby and I have no oily smell from under the hood or while driving. Yep, this could be the source of an oily smell from anyone running an ESC (or any forced induction for that matter) without a PCV side catch can and check valve.
