Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, wrench set, mechanic's stethoscope, engine oil, compression tester.
Ensure the vehicle is parked on a level surface and the engine is off before beginning any work.

2. Address Engine Oil Issues

Sub-steps:
1. Remove the oil filler cap and check the oil level using the dipstick.
2. If the oil level is low, add the recommended engine oil specific to the Camry's engine (typically 0W-20).
3. If the oil is dirty or contaminated, proceed to change the oil and filter.
  - Safety Warning: Allow the engine to cool before opening the oil drain plug.

3. Secure Loose Components

Sub-steps:
1. Inspect all visible components including engine mounts, exhaust hangers, and suspension parts.
2. Tighten or replace any loose or damaged components found during the inspection.

4. Repair Engine Compression Issues

Sub-steps:
1. If a compression test reveals low compression in one or more cylinders, perform a leak-down test to identify the source of the issue.
2. Depending on the results, consider repairing or replacing affected components such as piston rings or cylinder heads.

5. Final Assembly and Testing

Sub-steps:
1. Reassemble any components that were removed during inspection or repair.
2. Start the engine and listen for the knocking noise to ensure it has been resolved.
