Some 2015-2016 Lincoln MKC vehicles equipped with a 2.3 GTDI engine and built on or before Feb. 23, 2016 may exhibit a heavy continuous blue smoke with a burning oil smell after idling 10 minutes or longer.

Check the tag on the crankcase vent oil separator using a flashlight. Look through the opening to the right of the throttle body. If the tag has a bar code, the vehicle is not equipped with a high flow crankcase vent oil separator. Replace the crankcase vent oil separator. Reprogram the PCM to the latest calibration using IDS release 101.01 or higher.

The IDS tool will require a response to the following question: Is the vehicle equipped with G1FZ-6A785-A or later crankcase vent oil separator?. Answer “Yes”..the PCM software will be updated for the high flow crankcase vent oil separator.

The high flow separator is available as P/N G1FZ-6A785-A. You’ll also need an intake gasket P/N CJ5Z-9439-A.
