Solution

1. Preparation

Tools Required: OBD-II scanner, mechanic's stethoscope or screwdriver, socket set, torque wrench, oil catch pan.
Ensure the vehicle is parked on a flat surface and the engine is cool.
Disconnect the negative battery terminal to prevent any electrical issues.

2. Change Engine Oil and Filter

Sub-steps:
1. Place an oil catch pan under the oil pan.
2. Remove the oil drain plug and allow old oil to drain completely.
3. Replace the oil filter using an oil filter wrench.
4. Install a new oil filter and ensure it is tightened according to manufacturer specifications.
5. Reinstall the drain plug and tighten it to the specified torque (typically around 30 ft-lbs for Toyota).
6. Fill the engine with new oil (consult owner's manual for the correct type and capacity).

3. Adjust Valve Clearance (if necessary)

Sub-steps:
1. Remove the valve cover by unscrewing the bolts (torque specifications vary, consult manual).
2. Use a feeler gauge to check the clearance between the valve stems and rocker arms.
3. If out of specification, adjust the clearance by replacing shims or adjusting the rocker arms, as per service manual instructions.
4. Reinstall the valve cover with a new gasket and tighten bolts to specifications.

4. Inspect and Replace Timing Chain/Belt (if needed)

Sub-steps:
1. Remove necessary components to access the timing chain/belt (may include the timing cover).
2. Inspect the chain/belt for wear, slack, or missing teeth.
3. If needed, replace with a new timing chain/belt, ensuring all timing marks are aligned.
4. Reassemble components and double-check tightness.
