Also, have them check the oil pressure sending unit. Mine also had the "smell". I had the dealer check it while in for a service, and they found a very small leak from the sending unit. Oil was barely visible on the aero pan under the engine. They replaced the unit and did an oil change as part of the repair. Smell gone. Only problem In 25,000 miles.

Although Chrysler would not pay for the oil filter, they did pay for the Mobil 1, under warranty...go figure.
