Solution

1. Preparation

Tools Required: OBD-II scanner, mechanic's stethoscope, socket set, torque wrench, oil catch pan.
Safety Warnings: Ensure the engine is cool before starting any work. Disconnect the battery before working on electrical components.

2. Change Engine Oil and Filter

Sub-steps:
1. Warm up the engine slightly to thin the oil for a better drain.
2. Turn off the engine and allow it to sit for a few minutes.
3. Place an oil catch pan under the oil pan and remove the drain plug.

5. Replace the oil filter using an oil filter wrench.
6. Reinstall the drain plug and tighten to the manufacturer’s torque specifications.
7. Fill the engine with the appropriate type and amount of oil (usually 0W-20 synthetic oil).

3. Adjust or Replace Valvetrain Components

Sub-steps:
1. Remove the engine cover to access the valvetrain.
2. Check the clearance of the rocker arms using a feeler gauge and adjust as necessary.
3. Replace any worn components such as lifters or rocker arms if needed.
4. Reinstall the engine cover, ensuring all bolts are tightened to the specified torque.

4. Repair Exhaust System Leak

Sub-steps:
