Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.

Tools Required:

Socket set
Torque wrench
Oil filter wrench
Oil catch pan
Clean rags

2. Check and Top Off Engine Oil

Open the hood and locate the oil dipstick.
Remove the dipstick, wipe it clean, and reinsert it to check the oil level.
If low, add the correct type and grade of oil as specified in the owner’s manual.

3. Inspect and Repair Leaks

Visual Inspection: Look for oil leaks around the engine.
- If found, identify the source (e.g., oil pan, valve cover).
Remove and Replace Gaskets:
- If the valve cover gasket is leaking, remove the valve cover bolts using a socket set.
- Carefully lift the valve cover off, clean the mating surfaces, and replace the gasket.
- Torque the valve cover bolts to the manufacturer's specification.

4. Replace Oil Filter

Use an oil filter wrench to remove the old oil filter.
Apply a thin layer of new oil to the rubber O-ring of the new filter.
Install the new oil filter by hand, ensuring it is snug but not over-tightened.

5. Clean Up

After repairs, clean any spilled oil and ensure all tools are removed from the engine bay.
Run the engine for a few minutes to check for leaks around repaired areas.
