We had a 3.2 that started smoking badly and it was due to a faulty ambient air valve which was siphoning oil from the tank. It was simply bypassed/disconnected. The ambient air valve's purpose is to prevent throttle body freezing in cold temperatures.
Additionally, you aren't THAT far from Kansas City. I'd refer you to JPWerks for any air-cooled repair, small or large.
