Solution

1. Preparation

Gather tools and parts needed.
Make sure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to avoid electrical issues.

2. Locate the Source of the Leak

Using a flashlight, inspect the area where oil is pooling.
Clean the affected area with a degreaser to help identify the leak source after running the engine.

3. Replace Gaskets or Seals

If the oil leak is from the valve cover gasket:
- Tools Required: Socket set, torque wrench, gasket scraper.
- Remove the valve cover by unscrewing the bolts.
- Clean the surface of the engine and the valve cover thoroughly.
- Install a new gasket and reattach the valve cover, tightening bolts to the manufacturer's specifications (generally around 8-10 ft-lbs).
If the oil leak is from the oil pan:
- Tools Required: Socket set, torque wrench, gasket scraper, and possibly an oil catch pan.
- Drain the engine oil using an oil catch pan.
- Remove the oil pan by unscrewing the bolts and gently prying it off.
- Clean the oil pan and engine block surfaces.
- Install a new oil pan gasket and reattach the oil pan, tightening bolts to the manufacturer's specifications (typically around 10-15 ft-lbs).

4. Replace Oil Filter and Oil

Tools Required: Oil filter wrench, socket set.
Remove the old oil filter using an oil filter wrench.
Apply a thin layer of oil on the rubber gasket of the new oil filter and install it.
Refuel the engine with the appropriate oil type (usually SAE 5W-30 for Ford F-150) and check the level with the dipstick.
