Solution

1. Preparation

Tools Required: OBD-II scanner, mechanic's stethoscope, socket set, torque wrench.
Disconnect the negative battery terminal to ensure safety while working on the engine.

2. Engine Oil Change (if necessary)

Sub-steps:
1. Drain the old engine oil using a wrench to remove the oil drain plug.
2. Replace the oil filter using an oil filter wrench.
3. Reinstall the drain plug and torque to manufacturer specifications (typically around 30 ft-lbs).
4. Fill the engine with the appropriate type and amount of new engine oil (consult owner’s manual for specifications).

3. Adjust Valve Clearance (if applicable)

Sub-steps:
1. Remove the valve cover by loosening the bolts with a socket set.
2. Check the clearance using a feeler gauge and adjust as necessary by tightening or loosening the adjusting screws.
3. Reinstall the valve cover with a new gasket if necessary, torquing the bolts to the correct specifications.

4. Replace Timing Chain/Belt Tensioner (if faulty)

Sub-steps:
1. Remove any components obstructing access to the timing chain/belt cover (e.g., serpentine belt).
2. Remove the timing chain/belt cover by taking out the necessary bolts.
3. Inspect the tensioner; if it shows signs of wear, replace it with a new one.
4. Reassemble all components in reverse order, ensuring everything is torqued to specifications.
