Solution

1. Preparation

Gather all necessary tools and safety equipment.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to ensure safety during repairs.

2. Identify and Repair Leaks

Visual Inspection:
- Use a flashlight to inspect the oil pan, gaskets, and valve covers for leaks.
- Clean the area with a degreaser if necessary to spot new leaks after the vehicle runs.
Replace Leaking Gaskets/Seals:
- If leaks are found, remove the affected components (e.g., valve cover or oil pan).
- Replace old gaskets and seals with new ones, ensuring proper alignment.
- Torque bolts to the manufacturer's specifications.

3. Replace Oil Filter

Remove Old Oil Filter:
- Use an oil filter wrench to unscrew the old oil filter.
- Allow any residual oil to drain into a pan.
Install New Oil Filter:
- Apply a thin layer of fresh oil to the rubber gasket of the new filter.
- Screw on the new filter until snug, then tighten an additional 3/4 turn.

4. Change Engine Oil

Drain Old Oil:
- Place an oil drain pan under the oil pan.
- Remove the drain plug and allow the old oil to fully drain.
Add New Oil:
- Replace the drain plug after the oil has drained.
- Add the correct type and amount of new oil as specified in the owner’s manual.

5. Test for Issues

Start the engine and let it idle for a few minutes.
Check for any signs of leaks or burning oil smell.
