Solution

1. Preparation

Gather Tools: OBD-II scanner, mechanic's stethoscope, socket set, torque wrench, oil filter wrench, and new engine oil.
Safety Precautions: Ensure the engine is cool before starting work, and disconnect the battery if working on electrical components.

2. Change Engine Oil and Filter

Lift Vehicle: Use jack stands to elevate the vehicle safely.
Drain Old Oil: Remove the oil drain plug and let the old oil drain into a pan.
Replace Oil Filter: Use an oil filter wrench to remove the old filter; install the new filter, ensuring the rubber O-ring is lubricated.
Reinstall Drain Plug: Torque the drain plug to the manufacturer’s specifications (typically around 20-25 ft-lbs).
Add New Oil: Pour in the recommended type and amount of engine oil (usually 0W-20 for the Camry) through the oil filler cap.

3. Adjust Valve Clearance (if necessary)

Remove Valve Cover: Detach the valve cover by removing bolts with a socket set, and gently pry it off.
Check Valve Clearance: Use a feeler gauge to measure the clearance between the rocker arm and the valve stem; adjust as necessary by loosening the adjusting screw and retightening to specification.
Reinstall Valve Cover: Clean the gasket surface, apply new gasket material if needed, and torque the valve cover bolts to specification.

4. Inspect/Replace Timing Components (if necessary)

Remove Timing Cover: Take off the timing cover by unscrewing the bolts; ensure the engine is at TDC (Top Dead Center).
Inspect Timing Chain/Belt: Check for wear, stretching, or misalignment; replace if any issues are found.
Reassemble: Reinstall the timing cover and torque bolts to the specified value.
