Solution

1. Preparation

Gather tools and materials: OBD-II scanner, socket set, oil catch pan, clean rags, UV dye, UV light, pressure gauge.
Ensure the vehicle is parked on a flat surface and the engine is cool.

2. Clean Areas of Interest

Use a degreaser to clean the engine block, oil pan, and other suspected areas of oil leaks.
Rinse with water and dry with clean rags to ensure visibility of any new leaks.

3. Replace Leaking Components

Gasket Replacement:
- Remove any components obstructing access to the valve cover or oil pan.
- Remove the old gasket and clean the mating surfaces.
- Install the new gasket and torque to manufacturer specifications.
Oil Filter Replacement:
- Use an oil filter wrench to remove the old oil filter.
- Apply a small amount of oil to the rubber O-ring of the new filter.
- Install the new oil filter and tighten it to the recommended torque.
Rear Main Seal Replacement:
- Remove the transmission to access the rear main seal.
- Replace the old seal with a new one, ensuring proper alignment.
- Reinstall the transmission and torque to manufacturer specifications.

4. Refilling Oil

After repairs, refill the engine with the correct type and amount of oil as specified in the owner's manual.
Check for leaks around the replaced components after refilling.
