Increased Oil Consumption, DTC P0365/P0369, or Both

impacted vehicles 

Condition: Some 2017-2019 Ford F-150 2018-2019 Ford Expedition 2019 Lincoln Navigator The 3.5L EcoBoost engine in 2017-2019 F-150 and 2018-2019 Expedition/Navigator cars built on or before April 1, 2019, may display high oil consumption without obvious oil leaks, as well as diagnostic trouble codes (DTC) P0365 and/or P0369. 

Cause: A problem with the positive crankcase ventilation (PCV) system could be to blame for this. 

Follow the procedures in the service procedure to replace the valve covers after checking the condition and making the necessary corrections. 

Service Methodology: Service Methodology 

1. Check for engine oil leaks visually. Exist any obvious leaks right now? 

(1). This article does not apply, yes. Make use of the workshop manual (WSM). 

(2). If not, move on to Step 2. 

2. Remove the motor oil.

2. Remove the motor oil. Oil filter removal and replacement. 

3. Pour 4.7L (5 quarts) into the engine, which is 1L (1 quart) less than the recommended fill level. 

NOTE: Ensure that the car is parked on a flat surface. 

4. If the engine is hot, run it for 3 minutes; if it's cold, run it for 10. Cut the engine off. Record the oil level displayed on the oil level indicator by making a notation on the back of the oil level indicator after allowing for a minimum drain back duration of 15 minutes. 

5. To finish the standard oil fill, add the final 1L (1 quart). After starting the engine again, let it idle for two minutes. Cut the engine off. 

6. After a drain of 15 minutes

After the drain back time, indicate the new location of the oil level on the oil level indicator to note its location. 

NOTE: For the oil consumption test, do not utilize the manufacturer oil level indicator marks. Simply adhere to the marks shown on the oil level indicator in Steps 4 and 6. 

7. Describe to the customer where the oil should drop following an oil change with the recommended fill quantity using the factory-calibrated indications on the oil level indicator. Justify this by saying it might differ from MIN-MAX or the upper and lower holes on the oil level indicator. 

8. Note the mileage of the car. 

9. Inform the client that oil level indicator readings must be taken either weekly or every 320 kilometers (200 miles).

utilizing the updated markers as shown on the oil level indicator, daily, or weekly. Remind the customer that the engine needs to be shut down for at least 15 minutes, that the vehicle needs to be level in order to get an accurate reading, and that the oil level indicator needs to be securely inserted in the tube before taking the reading. 

10. Enter the vehicle's mileage once the successive indicator readings show that 1 full litter (1 quart) has been consumed. When performing this computation, take into account the drive cycle the car has been run under. To carefully track oil usage, it might be essential to ask the customer to bring the car in for routine oil level indicator readings. 

(1) If the car has covered at least 4,800 kilometres (3,000 mi)

Assuming oil consumption has not reached or exceeded 1L (1 quart (1.14 l)), the car is in good shape and shouldn't need any repairs. 

NOTE: For oil consumption measurements, only use the marks placed on the oil level indicator during Steps 4 and 6. This measurement is more accurate since it takes into account any variations in the marks on the manufacturer's oil level indicator. 

11. Calculate the distance between the mark made in Step 6 and the oil level indicator's current oil level. On the repair order, include this measurement in millimetres, the current vehicle mileage as determined in Step 10, and the starting mileage noted in Step 8. 

12. Is the observed oil usage greater than 1L (1 quart (1.14 l)) per 4,800 km (3,000 mi) or less? 

(1). Replace both valve covers, of course. 

(2). No, the car is in good working order and doesn't need any more repairs. The work has been finished.
