Solution

1. Preparation

Ensure the vehicle is parked on a level surface and the engine is cool.
Gather necessary tools and parts.
Disconnect the battery to ensure safety during repairs.

2. Inspect and Replace Engine Oil

Sub-steps:
1. Remove the oil drain plug using a socket set and drain the old oil into a pan.
2. Replace the oil filter using an oil filter wrench.
3. Install the new filter, ensuring the rubber O-ring is lubricated and seated properly.
4. Reinstall the drain plug and torque to manufacturer specifications (typically around 20-30 ft-lbs).
5. Add the manufacturer-recommended engine oil through the oil filler cap.

3. Address Engine Components

Sub-steps:
1. Inspect the timing chain/belt for wear; replace if necessary.
2. Check the valve lifters and rocker arms for proper operation; replace any worn components.
3. Tighten any loose bolts on the engine mounts to reduce vibration.
4. If knocking persists, consider replacing the affected cylinder head or piston based on compression test results.

4. Exhaust System Inspection

Sub-steps:
1. Visually inspect the exhaust manifold and joints for cracks or leaks.
2. Replace any damaged gaskets or components.
3. Secure any loose exhaust hangers or brackets.
