Solution

1. Preparation

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

2. Locate the Source of the Leak

Place a clean cardboard under the engine to catch drips and confirm the leak's origin.
Use a flashlight to inspect the suspected area for oil traces.

3. Replace Damaged Components

Oil Filter Replacement:
- Use an oil filter wrench to remove the old oil filter.
- Apply a thin layer of oil to the rubber gasket of the new filter.
- Install the new oil filter by hand, tightening it according to the manufacturer's specifications (usually hand-tight plus a quarter turn).
Oil Pan Gasket Replacement:
- Drain the engine oil using an oil catch pan.
- Remove the oil drain plug and allow oil to fully drain.
- Remove any bolts securing the oil pan (consult service manual for specific torque values).
- Carefully pry off the oil pan and remove the old gasket.
- Clean the mating surfaces with a scraper and ensure no debris remains.
- Place the new gasket on the oil pan and reinstall it, tightening bolts in a crisscross pattern to the manufacturer's specifications.

4. Refill Engine Oil

Reinstall the oil drain plug securely.
Refill the engine with the recommended type and amount of oil (usually found in the owner's manual).
Start the engine and allow it to run for a few minutes, then check for leaks.
