Solution

1. Preparation

Tools Required: Safety glasses, gloves, OBD-II scanner, socket set, torque wrench, engine oil.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the negative terminal of the battery for safety.

2. Inspect and Replace Engine Oil

Sub-steps:
1. Remove the oil drain plug using a socket wrench and drain the old oil into a suitable container.
2. Replace the oil filter using an oil filter wrench.
3. Reinstall the drain plug and torque to manufacturer specifications (typically 20-30 ft-lbs).
4. Fill the engine with new oil of the recommended type and viscosity (check the owner's manual).
5. Start the engine and let it run for a minute, then check for leaks.

3. Inspect and Replace Timing Chain/Belt Tensioner

Sub-steps:
1. Remove any coverings over the timing chain/belt area.
2. Check the tensioner for wear and proper function.
3. If faulty, remove the old tensioner and replace it with a new one, ensuring proper alignment.
4. Reinstall any coverings and ensure all fasteners are torqued to specifications.

4. Valvetrain Inspection

Sub-steps:
1. Remove the valve cover using a socket set.
2. Inspect the rocker arms, lifters, and pushrods for signs of wear or damage.
3. Replace any worn components with OEM parts.
4. Reinstall the valve cover with a new gasket to prevent leaks.
