After discovering oil in the PCV when I had it replaced recently, I decided it might be a good idea to put a catch on the Jeep to prevent that stuff from getting back into the intake. I picked up a J&L Oil Air separator which was an easy enough install. Reviews seem pretty good. I'll see how much oil this catches at the next oil change.
