Solution

1. Preparation

Gather all necessary tools and parts before starting the repair.
Ensure the vehicle is parked on a level surface and the engine is cool.

2. Addressing Oil Leaks

Identify Leak Source:
- Clean the engine area with an engine degreaser to remove old oil residue.
- Use a UV dye if necessary to trace the oil leak.
Replace Gaskets/Seals:
- If the leak is from the valve cover gaskets:
  1. Remove the engine cover (if applicable).
  2. Unscrew the valve cover bolts using a socket wrench.
  3. Remove the old gasket and clean the surfaces.
  4. Install the new gasket and reassemble the valve cover.
- For oil pan leaks:
  1. Drain the engine oil.
  2. Remove the oil pan bolts and carefully detach the oil pan.
  3. Replace the oil pan gasket and reattach the oil pan with specified torque (typically 10-15 ft-lbs).

3. Clean and Fill

Oil Change:
- If oil is burnt or contaminated, change the oil:
  1. Drain the remaining oil and replace the oil filter.
  2. Fill with the correct type and amount of engine oil (usually 0W-20 for Toyota Camry).

4. Final Inspection

Inspect all replaced components for proper installation and ensure no tools are left in the engine bay.
Start the engine and check for leaks around the repaired areas.
