Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to prevent any electrical issues.

2. Locate and Repair Oil Leaks

Inspect Gaskets and Seals:
- Remove any engine covers or components obstructing access to the valve cover gasket.
- Inspect the valve cover gasket for wear or damage.
- If damaged, remove the old gasket and clean the mating surfaces. Install a new gasket, ensuring proper alignment.
Check the Oil Filter:
- Verify that the oil filter is securely tightened.
- If leaking, replace the oil filter with a new one and ensure it is properly installed.

3. Change Oil and Filter

Drain Engine Oil:
- Place a drain pan underneath the oil pan.
- Remove the drain plug using a socket set and allow the oil to completely drain.
Replace Filter and Refill Oil:
- Install a new oil filter.
- Replace the drain plug and torque to manufacturer specifications (typically around 18-25 lb-ft).
- Refill the engine with fresh oil of the recommended type and capacity (usually 0W-20 for the Camry).

4. Clean Up and Final Checks

Clean any spilled oil from the engine bay.
Reconnect the battery and ensure all components are secured.
Start the engine and check for leaks around the repaired areas.
