Solution

1. Preparation

Tools Required: Socket set, mechanic's stethoscope, OBD-II scanner, torque wrench.
Safety Warnings: Disconnect the battery before working on electrical systems.

2. Change Engine Oil and Filter

Lift the Vehicle: Use a jack to lift the vehicle and secure it on jack stands.
Drain Oil: Remove the oil drain plug and let the old oil drain completely into a collection pan.
Replace Oil Filter: Use an oil filter wrench to remove the old oil filter. Apply a little new oil on the gasket of the new filter and install it.
Reinstall Drain Plug: Torque the oil drain plug to the manufacturer's specifications (usually around 25 Nm).
Fill New Oil: Add new engine oil as per the manufacturer's specifications (typically 5W-30 or 0W-40).

3. Inspect and Adjust Valve Train

Remove Valve Cover: Unscrew and carefully remove the valve cover to access the valve train.
Inspect Components: Check for worn rockers, pushrods, and lifters. Replace any damaged components.
Adjust Valve Clearance: If applicable, adjust the valve clearance to specifications as per the manufacturer's guidelines.
Reinstall Valve Cover: Clean the mating surfaces, apply a new gasket, and reinstall the valve cover with proper torque.

4. Inspect Timing Chain/Belt

Remove Timing Cover: Disconnect any components obstructing the timing cover and remove it.
Inspect Timing Chain/Belt: Check for wear, slack, or damage. Replace if necessary.
Reinstall Timing Cover: Ensure all connections are secure and torque to specifications.
