19green97 Posted September 6, 2022 Report Share Posted September 6, 2022 Hey all, I've owned my mkx for over a year now. I already know the issue in regards to the oil pan/sensor leaks. Sadly I have gotten to that point, I'm replacing the sensor because the drops are coming from that side, not the pan. Where is the location of the sensor? Facing the car I'm assuming it's to your left, and I'm sure I found it I just want to re confirm that the location is on the lower area of the engine? That part is covered in oil and everything below it Is as well so that is my best assumption. Car only has 50k miles. Thanks! Quote Link to comment Share on other sites More sharing options...
Haz Posted September 6, 2022 Report Share Posted September 6, 2022 Perhaps you are referring to the Oil Pressure Control Solenoid, the red-circled Item #1, shown in the below illustrations?... If so, this Service Procedure should be helpful to you: Oil Pressure Control Solenoid - Removal and Installation - 2016 MKX Workshop Manual.pdf (Download Link) Good luck! 19green97 1 Quote Link to comment Share on other sites More sharing options...
19green97 Posted September 7, 2022 Author Report Share Posted September 7, 2022 @Haz on all parts sites its listed as oil pressure sending unit. I even called a lincoln dealer and spoke to parts and it's all the same thing I guess they just have multiple names for it. So I was definitely looking in the right spot then. Mine is just slightly different than the one in the manual you showed me instead of it having a 90 degree angle to plug the sensor it's just completely straight. I'm tired of working on cars lol. Another question. Do I need to drain oil when replacing this Quote Link to comment Share on other sites More sharing options...
Haz Posted September 7, 2022 Report Share Posted September 7, 2022 Because the R&I procedure does not list draining the oil as a process-step, I doubt that it should be necessary, but it would be prudent to have a container at hand to catch drips that may occur initially when you remove the sensor/solenoid. And it is odd that parts department naming often does not match Workshop Manual descriptions. Good luck! Quote Link to comment Share on other sites More sharing options...
19green97 Posted September 12, 2022 Author Report Share Posted September 12, 2022 @Haz so i went under the car and im sure i got the wrong part, although they said it was for my year make and model idk where it goes. Ill post some photos, maybe you can give me insight if its the pan or the solenoid? Its dripping dirrectly under the oil filter, but i double checked and its on there good and properly. Is the solenoid known to cause leaks? Can oil also be prssent above the solenoid from the wind and what not. I dont have a skid plate. Also note i did wipe the solenoid Quote Link to comment Share on other sites More sharing options...
19green97 Posted September 12, 2022 Author Report Share Posted September 12, 2022 @Haz I can't add nay more images but on the solenoid side is where the oil is, above and below that location but not on any pulleys. Right side of oil pan is wet (solenoid side) left side is quite a bit more dry Quote Link to comment Share on other sites More sharing options...

Haz Posted September 13, 2022 Report Share Posted September 13, 2022 (edited) Beginning with the engine oil pressure sensor, below are PDF download links to relevant sections of the 2016 MKX Workshop Manual... Engine Oil Pressure (EOP) Sensor - Location Illustration - 2016 MKX Workshop Manual .pdf Engine Oil Pressure (EOP) Sensor - Removal and Installation - 2016 MKX Workshop Manual.pdf Engine Oil Pressure (EOP) Sensor - Connector C1642 Wiring Details - 2016 MKX Workshop Manual .pdf Engine Oil Pressure (EOP) Sensor - Wiring Diagram - 2016 MKX Workshop Manual .pdf Your photos show relatively widespread surfaces that have been dampened & soiled while driving at speed. The Workshop Manual provides the following methods that a dealership technician would use to evaluate potential points of leakage... Engine Oil Leaks NOTE: If an overnight drive is done, the fan air or road air blast can cause erroneous readings. NOTE: When diagnosing engine oil leaks, the source and location of the leak must be positively identified prior to repair. Prior to carrying out this procedure, clean the cylinder block, cylinder heads, valve covers, oil pan and flywheel/flexplate with a suitable solvent to remove all traces of oil. Engine Oil Leaks - Fluorescent Oil Additive Method Use the 12 Volt Master UV Diagnostic Inspection Kit to carry out the following procedure for oil leak diagnosis. Add 29.6 ml (1 oz) of Dye-Lite® Gasoline Engine Oil Leak Detection Dye to a minimum of 0.47L (1/2 qt) and a maximum of 0.95L (1 qt) engine oil and fill through the engine oil fill. Thoroughly premix the gasoline engine oil leak detection dye or it will not have enough time to reach the crankcase, oil galleries and seal surfaces during this particular 15 minute test. The additive must be mixed well with oil and added through the oil fill. Check the level on the oil level indicator to determine what amount of oil to premix. If it is in the middle of the crosshatch area or below the full mark, use 0.95L (1 qt). If it is at the full mark, use 0.47L (1/2 qt). Run the engine for 15 minutes. Stop the engine and inspect all seal and gasket areas for leaks using the UV Leak Detector Kit. A clear bright yellow or orange area will identify the leak. For extremely small leaks, several hours may be required for the leak to appear. At the end of test, make sure the oil level is within the upper and lower oil indicator marks. Remove oil as necessary if it registers above the full mark. Leakage Points - Underhood Examine the following areas for oil leakage: Valve cover gaskets Cylinder head gaskets Oil cooler, if equipped Oil filter adapter Engine front cover Oil filter adapter and filter body Oil level indicator tube connection Oil pressure switch or EOP sensor Turbocharger oil tubes Leakage Points - Under Engine, With Vehicle on Hoist Examine the following areas for oil leakage: Oil pan gaskets Oil pan sealer Engine front cover gasket Crankshaft front seal Crankshaft rear oil seal Oil filter adapter and filter body Oil cooler, if equipped Turbocharger oil tubes Leakage Points - With Transmission and Flywheel/Flexplate Removed Examine the following areas for oil leakage: Crankshaft rear oil seal Rear main bearing cap parting line Flexplate mounting bolt holes (with flexplate installed) Pipe plugs at the end of oil passages Whether you choose to do it yourself without the benefit of fluorescent oil additive, or, if you prefer to hand off the task to dealership Service personnel, a thorough cleaning of the engine is the first step toward clearly recognizing the source of the leak.

Haz Posted September 15, 2022 Report Share Posted September 15, 2022 If your further investigation points to the oil pan as a leak source, the below Technical Service Bulletin relating to that condition on 2.7L/3.0L EcoBoost engines may be helpful...
