Solution

1. Preparation

Tools Required: OBD-II scanner, oil pressure gauge, mechanic's stethoscope, compression tester, socket set.
Safety Warnings: Disconnect the battery before starting any electrical work. Allow the engine to cool before performing inspections.

2. Address Engine Oil Issues

Sub-step 1: If oil level is low, top up with the manufacturer's recommended oil type.
Sub-step 2: If oil is contaminated, perform an oil change, replacing the oil filter as well.
Sub-step 3: Run the engine and monitor noise. If knocking persists, proceed to the next step.

3. Inspect and Replace Worn Components

Sub-step 1: If compression test reveals low compression, consider replacing piston rings or cylinder head gasket, depending on findings.
Sub-step 2: If timing components are found to be worn, replace the timing belt/chain and any associated tensioners or guides.
Sub-step 3: Tighten any loose components found during inspection.

4. Reassemble and Clean Up

Sub-step 1: Reinstall any components removed for inspection and ensure all bolts are torqued to specifications.
Sub-step 2: Clear any engine codes using the OBD-II scanner after repairs.
Sub-step 3: Dispose of any used oil and filters according to local regulations.
