Solution

1. Preparation

Gather tools and materials: OBD-II scanner, socket set, torque wrench, oil catch pan, rags, and replacement gaskets or seals as needed.
Ensure the vehicle is parked on a level surface and the engine is cool.

2. Address Oil Leaks

Identify the Source of the Leak:
- Inspect the valve cover gasket. If it appears worn or oil is pooling, it may need replacement.
- Check the oil pan gasket for leaks, particularly around the edges.
- Look for leaks around the oil filter and ensure it is properly tightened.
Replace Gaskets/Seals:
- For the valve cover:
  - Remove any engine covers obstructing access.
  - Unbolt the valve cover using a socket set.
  - Remove the old gasket and clean the mating surfaces with a rag.
  - Install a new gasket and reassemble the valve cover, torquing bolts to manufacturer specifications (typically around 8-12 ft-lbs).
- For the oil pan:
  - Drain the engine oil into an oil catch pan.
  - Remove the oil pan bolts and gently pry the pan off.
  - Replace the old oil pan gasket and reinstall the oil pan, ensuring it is torqued properly (typically around 10-15 ft-lbs).

3. Refill Engine Oil

After addressing leaks, refill the engine with fresh oil according to manufacturer specifications (typically 5W-30 for most Camry models).
