Solution

1. Preparation

Tools Required: OBD-II scanner, mechanic's stethoscope, socket set, oil filter wrench, torque wrench.
Safety Warnings: Disconnect the battery before working on electrical systems. Allow engine to cool before opening any components.

2. Change Engine Oil and Filter

Sub-steps:
1. Lift Vehicle: Use a jack and jack stands to secure the vehicle if necessary.
2. Drain Old Oil: Place an oil catch pan under the oil pan, remove the oil drain plug, and allow oil to drain completely.
3. Replace Oil Filter: Use an oil filter wrench to remove the old oil filter. Apply a small amount of new oil to the rubber gasket of the new filter and install it.
4. Reinstall Drain Plug: Replace the drain plug and torque it to the manufacturer’s specified value (typically around 25 ft-lbs).
5. Add New Oil: Pour in the appropriate type and amount of new engine oil (5W-20 is typical for many Corollas).

3. Inspect and Adjust Valvetrain Components

Sub-steps:
1. Remove Valve Cover: Unbolt and carefully remove the valve cover, ensuring no debris falls into the engine.
2. Inspect Lifters and Rocker Arms: Check for wear on lifters and rocker arms; replace if necessary.
3. Adjust Valve Clearance: If applicable, adjust valve clearance according to manufacturer's specifications.
4. Reinstall Valve Cover: Clean the gasket surface and apply a new gasket or RTV sealant. Torque bolts to specified value (typically 7 ft-lbs).

4. Check for Exhaust Leaks

Sub-steps:
1. Inspect Exhaust System: Visually check for cracks or loose connections in the exhaust manifold and pipes.
2. Use a Smoke Machine: Introduce smoke into the exhaust system to identify leaks.
3. Repair Leaks: Tighten connections or replace damaged sections of the exhaust system.
