Solution

1. Preparation

Ensure the vehicle is parked on a flat surface and the engine is cool.
Disconnect the negative battery terminal to prevent electrical shorts.
Gather necessary tools and parts.

2. Check and Change Engine Oil

Tools Required: Socket set, oil filter wrench, oil catch pan, funnel.
Remove the oil drain plug and allow old oil to drain completely into the catch pan.
Replace the oil filter using an oil filter wrench.
Install a new oil filter, ensuring the rubber gasket is lubricated and seated properly.
Reinstall the oil drain plug, tightening it to the manufacturer’s specified torque value (typically around 25 ft-lbs).
Add new engine oil (recommended type: 0W-20) using a funnel to prevent spills.

3. Inspect and Replace Worn Components

Tools Required: Socket set, torque wrench, replacement parts (if needed).
Inspect the engine mounts for wear; replace if cracked or deteriorated.
Check the timing belt/chain for proper tension and condition; replace if necessary.
If knocking persists, inspect the connecting rods and bearings, which may require engine disassembly.

4. Fuel System Inspection

Tools Required: Fuel pressure gauge, multimeter.
Check fuel pressure with a gauge to ensure it’s within specifications.
If low pressure is detected, inspect the fuel pump, fuel filter, and fuel lines for blockages or failures.
Clean or replace fuel injectors as needed.

5. Reassemble and Final Checks

Reconnect the negative battery terminal.
Start the engine and listen for any abnormal noises.
Check for leaks around the oil filter and drain plug after oil replacement.
