Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cold.
Disconnect the battery to prevent any electrical issues.

2. Drain Engine Oil

Tools Required: Socket set, oil catch pan
Place the oil catch pan beneath the oil drain plug.
Use the socket set to remove the drain plug and allow the oil to fully drain into the pan.
Replace the drain plug and torque it to the manufacturer's specification (typically around 30 lb-ft for a Camry).

3. Replace Oil Filter

Tools Required: Oil filter wrench
Locate the oil filter and use the oil filter wrench to remove it.
Lubricate the rubber seal of the new oil filter with a bit of new oil.
Install the new oil filter by hand until snug, then tighten an additional 3/4 turn.

4. Inspect and Replace Gaskets (if needed)

Tools Required: Torque wrench, gasket scraper, RTV silicone (if applicable)
If the valve cover gasket or oil pan gasket is leaking, remove the necessary components to access these gaskets.
Remove old gaskets using a scraper, ensuring the surface is clean.
Install new gaskets, applying any necessary RTV silicone as per the manufacturer's specifications.
Reassemble components and torque to the specified values.

5. Refill Engine Oil

Tools Required: Funnel
Use a funnel to refill the engine with the appropriate type and amount of oil (typically 0W-20 for the Camry).
Check the oil level with the dipstick to ensure it's at the correct level.
