Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, torque wrench, automotive stethoscope.
Safety Warnings: Disconnect the battery before working on electrical components. Allow the engine to cool before starting any work.

2. Change Engine Oil and Filter

Sub-steps:
1. Raise the vehicle using a jack and secure it on jack stands.
2. Remove the drain plug and let the old oil drain into a container.
3. Replace the oil filter using an oil filter wrench.
4. Install the drain plug with a new washer and torque to specifications (typically around 25 Nm).
5. Add new engine oil (refer to owner’s manual for the correct type and capacity).

3. Replace Valve Lifters (if necessary)

Sub-steps:
1. Remove the engine cover by unbolting it and disconnecting any electrical connectors.
2. Remove the valve cover bolts and lift the cover off carefully.
3. Remove the old valve lifters using a magnet or lifter tool.
4. Install new valve lifters, ensuring they are seated correctly.
5. Reinstall the valve cover with a new gasket, tightening the bolts to manufacturer specifications (typically around 10 Nm).

4. Inspect and Adjust Timing Chain/Belt (if necessary)

Sub-steps:
1. Remove any components obstructing access to the timing chain/belt.
2. Check the tensioner for proper tension and replace if worn.
3. Replace the timing chain/belt if there are signs of wear.
4. Reassemble all components and ensure everything is torqued to specification.
