Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to ensure safety while working on the vehicle.
Allow the engine to cool down before beginning work.

2. Engine Oil Change

Sub-steps:
- Drain the old engine oil using an oil pan and a wrench to remove the oil drain plug.
- Replace the oil filter with a new one; apply a thin layer of oil to the rubber gasket of the new filter before installation.
- Refill the engine with the recommended type and amount of oil (consult owner’s manual for specifications).

Tools Required:

Oil wrench
Oil drain pan
Socket set

3. Inspect and Replace Components

Sub-steps:
- If knocking persists, inspect the timing chain/belt for wear and alignment; replace if necessary.
- Check the connecting rod bearings; if damaged, replace the bearings and confirm proper torque specifications.
- If compression tests reveal low pressure, consider an engine rebuild or replacement if necessary.

Tools Required:

Torque wrench
Engine hoist (if applicable)

4. Reassemble and Test

Sub-steps:
- Reassemble any removed components carefully, ensuring all bolts are torqued to specification.
- Reconnect the battery and clear any diagnostic codes from the ECM.
- Start the engine and monitor for any unusual noises or symptoms.
