2. Identify Leak Source

Clean the area around suspected leak points using an engine degreaser.
Use a UV dye if required, following the manufacturer's instructions, to help pinpoint the leak.

3. Replace Gaskets or Seals

Oil Filter Replacement:
- Use an oil filter wrench to remove the old oil filter.
- Lubricate the rubber O-ring of the new filter with fresh oil.
- Install the new oil filter by hand until snug, then tighten an additional 3/4 turn.
Drain Plug Replacement:
- Place a drain pan underneath the oil pan.
- Use a socket wrench to remove the drain plug.
- Inspect the washer and replace it if damaged.
- Reinstall the drain plug and torque it to 25 Nm (18 lb-ft).
Gasket Replacement:
- For the oil pan, remove the bolts securing it and gently pry it off.
- Clean the mating surfaces thoroughly.
- Apply a new gasket or sealant as specified in the service manual.
- Reinstall the oil pan and torque the bolts to the manufacturer's specifications (usually around 10-12 Nm or 7-9 lb-ft).

4. Refill Engine Oil

Use a funnel to pour the recommended type and quantity of engine oil back into the engine.
Check the oil level using the dipstick and adjust as necessary.

5. Final Checks

Reconnect the battery.
Start the engine and let it idle for a few minutes while checking for leaks.
Monitor the oil level once more after the engine has run to ensure proper levels.
