Solution

1. Preparation

Gather necessary tools and parts.
Ensure the engine is cool and the vehicle is parked on a level surface.
Disconnect the battery to avoid any electrical issues during inspection.

2. Identify and Repair Oil Leaks

Inspect Valve Cover Gasket:
- Remove any engine covers if necessary.
- Check the valve cover gasket for cracks or wear.
- If damaged, replace the gasket with a new one. Torque to manufacturer specifications (typically around 8-10 ft-lbs).
Check Oil Filter:
- Inspect the oil filter for any signs of leakage.
- If the filter is leaking, replace it with a new one and ensure it is properly tightened.

3. Clean Affected Areas

Use a degreaser to clean any oil residue from the engine bay and surrounding components.
Rinse with water and allow the area to dry completely.

4. Refill Engine Oil

If the oil level is low, refill with the appropriate type of oil (typically 0W-20 for most Toyota Camrys).
Check the owner’s manual for the correct oil specifications and capacity.

5. Final Assembly

Reattach any engine covers or components that were removed during the inspection.
Reconnect the battery.
