Solution

1. Preparation

Tools Required: OBD-II scanner, engine oil dipstick, mechanic's stethoscope, compression tester, socket set.
Safety Warnings: Disconnect the battery before working on electrical systems; allow the engine to cool before inspection.

2. Address Engine Oil Issues

Sub-steps:
1. Remove the oil filler cap and check the oil level using the dipstick.
2. If low, add the recommended engine oil type (refer to owner’s manual for specifications).
3. If the oil is dirty or old, perform an oil change:
  - Drain the old oil using a wrench to remove the oil pan bolt.
  - Replace the oil filter using an oil filter wrench.
  - Refill with new oil.

3. Repair or Replace Faulty Components

Sub-steps:
1. If the compression test indicates low compression in any cylinder, inspect and replace worn piston rings or valves.
2. If knocking is due to a loose component, tighten any loose bolts or brackets found during visual inspection.
3. For any damaged engine mounts, replace them following the specific torque specifications outlined in the service manual.

4. Fuel System Check

Sub-steps:
1. If poor fuel quality is suspected, drain the fuel tank using a siphon or fuel pump.
2. Refill with high-octane fuel that meets manufacturer specifications.
3. Check the fuel injectors for clogs or leaks and clean or replace as necessary.
