Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface, and the engine is cool.
Disconnect the battery to prevent electrical issues.

2. Check for Leaks

Tools Required: Shop towels, flashlight
Inspect the engine bay and undercarriage for oil spots or leaks.
Clean any oil residue found to better identify ongoing leaks.

3. Replace Gaskets or Seals

Tools Required: Socket set, torque wrench, gasket scraper
Remove any components obstructing access to the valve cover or oil filter.
Replace the valve cover gasket if damaged; ensure to use the correct torque specifications (typically around 85 in-lbs for Ford engines).
If the oil filter is leaking, replace it with a new one, ensuring to apply a thin layer of oil on the rubber gasket before installation.

4. Clean and Inspect Exhaust Components

Tools Required: Wire brush, cleaning solvent
Clean the exhaust manifold and surrounding areas to remove oil residue.
Inspect for burnt oil, and replace any affected parts if necessary.

5. Refill Oil

Tools Required: Oil funnel
If oil level was low, refill with the manufacturer-recommended oil type (consult owner’s manual for specifications).
