Solution

1. Preparation

Gather Tools: OBD-II scanner, mechanic's stethoscope, socket set, feeler gauge, torque wrench.
Safety Precautions: Ensure the vehicle is on level ground, park with the parking brake engaged, and allow the engine to cool.

2. Change Engine Oil

Drain Oil: Remove the oil drain plug and drain the old oil into a container.
Replace Oil Filter: Use an oil filter wrench to remove the old oil filter, then install a new filter, ensuring the rubber gasket is lubricated.
Add New Oil: Reinstall the drain plug and fill the engine with the recommended type and amount of oil (5W-20 or as specified in the owner’s manual).

3. Adjust Valve Clearance

Remove Valve Cover: Disconnect any components obstructing access to the valve cover and remove the cover.
Check Clearance: Use a feeler gauge to measure the valve clearance. Compare with factory specifications.
Adjust as Necessary: If clearance is not within specifications, adjust the valve lash using the appropriate shims or screw adjustments.

4. Inspect Timing Chain/Belt

Remove Timing Cover: If the noise is suspected from the timing components, remove the timing cover.
Inspect Components: Check for any wear or damage to the timing chain or belt, guides, and tensioners. Replace if necessary.
