Solution

1. Preparation

Tools Required: OBD-II scanner, mechanic’s stethoscope, socket set, torque wrench, oil filter wrench.
Safety Warnings: Disconnect the battery before beginning any work on the engine. Allow the engine to cool before inspecting any components.

2. Change Engine Oil and Filter

Sub-steps:
1. Raise the vehicle and secure it on jack stands.
2. Remove the drain plug and allow the old oil to drain completely.
3. Replace the oil filter using an oil filter wrench.
4. Reinstall the drain plug and torque it to the manufacturer’s specifications (usually around 30 ft-lbs).
5. Fill the engine with the recommended engine oil (typically 0W-20 for the Camry) up to the appropriate level.

3. Adjust Valve Clearance

Sub-steps:
1. Remove the valve cover by unscrewing the bolts and carefully lifting it off.
2. Use a feeler gauge to measure the gap between the valve stem and rocker arm.
3. If the clearance is out of specification, adjust it by adding or removing shims as necessary.
4. Reassemble the valve cover, ensuring a proper seal and torque the bolts to manufacturer specifications (usually around 7 ft-lbs).

4. Inspect Timing Chain/Belt

Sub-steps:
1. Remove any components obstructing access to the timing chain/belt cover.
2. Inspect the chain/belt for signs of wear or slack; replace if necessary.
3. Ensure that the tensioner is functioning correctly and adjust as needed.
4. Reinstall any components and cover, torquing to specifications.
