Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface, and the engine is cool.
Disconnect the battery if working on electrical components.

2. Inspect and Repair Oil Leaks

Inspect Valve Covers:
- Remove any components obstructing access (e.g., air intake).
- Check the valve cover gaskets for cracks or wear. Replace if necessary.
- Tools Required: Socket set, torque wrench, gasket scraper.
Inspect Oil Pan:
- Check for any signs of leaks around the oil pan.
- If leaking, drain the oil and remove the oil pan.
- Replace the oil pan gasket and reassemble, ensuring proper torque specifications (typically 12-15 ft-lbs).

3. Replace Oil Filter

Removal:
- Use an oil filter wrench to remove the old oil filter. Discard properly.
Installation:
- 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.

4. Refill Engine Oil

Drain any old oil remaining in the crankcase.
Refill with the manufacturer-recommended oil type (typically 0W-20 for Camry) using a funnel.
Check the oil level with the dipstick and add more oil if necessary.
