Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is on a level surface and the engine is cool.
Disconnect the negative terminal of the battery for safety.

2. Identify and Repair Leaks

Inspect Oil Filter and Drain Plug:
- Use an oil filter wrench to remove the oil filter.
- Check the rubber O-ring for damage; replace if necessary.
- Tighten the drain plug to the manufacturer’s torque specifications (usually around 25-30 Nm).
Replace Oil Filter:
- Apply a small amount of new oil to the rubber O-ring on the new oil filter.
- Install the new oil filter hand-tight plus a quarter turn.

3. Replace Damaged Seals or Gaskets

Remove Affected Components:
- Depending on where the leak is found, remove any necessary components (e.g., intake manifold, valve cover) to access the gaskets.
Replace Seals/Gaskets:
- Clean the mating surfaces to ensure proper sealing.
- Apply gasket maker as per manufacturer specifications or place the new gasket.
- Reinstall components, ensuring all bolts are torqued to specification.

4. Oil Change

Drain Old Oil:
- Place an oil catch pan under the drain plug and remove it to drain the old oil completely.
Add New Oil:
- Replace the drain plug and tighten to specifications.
- Add new oil (check owner’s manual for correct type and quantity).

5. Final Checks

Start the engine and let it idle, checking for any leaks.
Monitor the oil level and ensure the smell of burning oil has dissipated.
