Solution

1. Preparation

Ensure safety: Disconnect the battery to prevent any electrical issues.
Gather tools: OBD-II scanner, socket set, torque wrench, stethoscope, compression tester, and engine oil.

2. Oil Change

Drain old oil:
- Place a drain pan under the oil pan.
- Remove the oil drain plug using a socket wrench and allow oil to fully drain.
Replace oil filter:
- Use an oil filter wrench to remove the old filter.
- Lubricate the rubber O-ring of the new filter with fresh oil and install it.
Refill engine oil:
- Replace the oil drain plug and tighten to manufacturer’s torque specifications (typically around 25 ft-lbs).
- Add new engine oil through the oil filler cap. Use the recommended oil type (usually 0W-20 or 5W-20).

3. Engine Inspection

Inspect components:
- Remove the engine cover (if applicable) and visually inspect for any loose or damaged parts.
- Check all accessible bolts and components to ensure they are tightened securely.
Perform Compression Test:
- Remove spark plugs and insert the compression tester into each cylinder.
- Crank the engine and record the compression readings; compare them to manufacturer specifications (typically 180-200 psi).

4. Address Timing Components

Inspect timing components:
- If knocking persists, remove the timing cover to inspect the timing chain/belt and tensioners.
- Replace worn or damaged components as necessary, following torque specifications for installation.
