Some 2016-2017 Ford F-150 trucks equipped with a 2.7L GTDI engine and built on April 1, 2016, through Jan. 1, 2017, may exhibit white or blue smoke from the exhaust, and rough idle in neutral and park at normal operating temperatures or after a hot restart. The MIL may be on. DTCs P0300, P0301, P0302, P0303, P0304, P0305, P0306, P0316, P0524 and/or P06DD may be set along with excessive oil consumption (oil consumption may be one quart in less than 3000 miles.

If DTCs P0524 and/or P06DD are not stored in the PCM, replace the cylinder heads.

If these DTCs are stored, check oil level. If level is not within the minimum and maximum marks on the indicator, add oil to correct level and run the engine to normal operating temperature, and check to see if oil pressure is within specification. If oil pressure meets specs, replace the cylinder heads. If oil level was initially within spec, run the engine to check oil pressure. If pressure is not within spec, Ford recommends replacing the long block assembly.
