Solution

1. Preparation

Ensure the vehicle is parked on a level surface and the engine is off.
Gather tools and materials: oil, filter, wrenches, torque wrench, multimeter, and OBD-II scanner.

2. Check and Change Engine Oil

Sub-steps:
1. Remove the dipstick and check the oil level; top off if low.
2. If oil is dirty or low, drain the old oil using an oil pan.
3. Replace the oil filter using an oil filter wrench.
4. Refill with the manufacturer-recommended oil type (e.g., 0W-20).
5. Start the engine and check for noise; if noise persists, proceed to the next step.

3. Inspect and Adjust Valve Clearance

Sub-steps:
1. Remove the engine cover to access the valve train.
2. Use a feeler gauge to measure the valve clearance.
3. If out of specification, adjust the clearance by loosening the rocker arm bolts.
4. Torque the bolts to the manufacturer's specifications (typically 16-22 ft-lbs).
5. Reinstall the engine cover and check for noise again.

4. Inspect Timing Chain/Belt Tensioner

Sub-steps:
1. Remove necessary components to access the timing chain/belt area.
2. Inspect the tensioner for wear or failure; replace if necessary.
3. Ensure proper tension on the chain/belt; adjust if needed.
4. Reassemble all components and check for noise.
