Problem Statement

Learn how to diagnose and repair a persistent oil leak in your 2020 Ford Explorer with step-by-step instructions and required tools.

Affected Component

engine oil system

Estimated Time

4-6 hours

Symptoms

•Visible oil spots under the vehicle when parked.
•Low oil level warning light on the dashboard.
•Oil residue on engine components or the underside of the vehicle.
•Burning oil smell, especially after prolonged driving.

Diagnostic Steps

1
Park the vehicle on a flat surface and turn off the engine.
2
Look for oil puddles or drips underneath the engine and transmission.
3
Inspect the engine bay for oil residue around gaskets, seals, and the oil filter.
4
Use the dipstick to check the oil level. If it's low, top off with the appropriate oil and monitor for further leaks.
5
Clean the engine and surrounding areas with a degreaser.
6
Start the engine and allow it to run for a few minutes, then shut off.
7
Inspect for fresh oil leaks. Pay special attention to valve cover gaskets, oil filter and oil pan, rear main seal, timing cover and front crankshaft seal.
8
Use an OBD-II scanner to check for any related fault codes that may indicate oil pressure issues or other engine problems.

Oil residue on engine components or the underside of the vehicle.
Burning oil smell, especially after prolonged driving.

Tools Required

Basic Hand Tools:
- Socket set (metric and standard)
- Wrench set
- Screwdrivers (flathead and Phillips)
Specialized Tools:
- Oil filter wrench
- Torque wrench
- Oil catch pan
Diagnostic Tools:
- OBD-II scanner
- Pressure gauge (for oil pressure testing)
Cleaning Supplies:
- Degreaser
- Rags or shop towels

Repair Instructions

Step 1: Address the Source of the Leak

Oil Filter Replacement:
- If the oil filter is found to be leaking, replace it:
  - Warm up the engine slightly (not too hot to touch).
  - Place oil catch pan under the filter.
  - Remove the old oil filter using the oil filter wrench.
  - Clean the mounting surface on the engine.
  - Apply a thin layer of new oil to the rubber gasket on the new filter.
  - Install the new filter, hand-tightening it (do not over-tighten).
Replace Valve Cover Gasket:
- If oil is leaking from the valve cover:
  - Remove any components obstructing access (e.g., intake manifold).
  - Unbolt the valve cover using the socket set.
  - Remove the old gasket and clean the mating surfaces.
  - Install the new gasket and reassemble in reverse order.
Oil Pan Gasket Replacement:
- If oil is leaking from the oil pan:
  - Raise the vehicle using jack stands.
  - Drain the engine oil into the oil catch pan.
  - Remove the oil pan bolts and gently pry the pan away from the engine.
  - Clean the mating surfaces thoroughly.
  - Install the new gasket and reassemble the oil pan.
Inspect Rear Main Seal:
- If oil is leaking from the rear main seal:
  - This requires removing the transmission. It is a more complex procedure:
    - Disconnect the battery.
    - Remove the driveshaft and lower the transmission.
    - Replace the rear main seal and reassemble.

Step 2: Final Checks

Refill Engine Oil:
- Once repairs are made, refill the engine oil to the proper level.
Run the Engine:
- Start the engine and let it run for a few minutes.
- Inspect for any new leaks.
Monitor Fluid Levels:
- Check the oil level after a short drive and top off if necessary.
Test Drive:
- Take the vehicle for a test drive and monitor for any signs of leaking oil.

Conclusion

By following these steps, you can effectively diagnose and repair a persistent oil leak in your 2020 Ford Explorer. If the leak persists after these repairs or if you encounter any difficulties, consult a professional mechanic for further assistance.
