Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, mechanic’s stethoscope, feeler gauge.
Ensure the vehicle is parked on a level surface and the engine is turned off.
Disconnect the battery if necessary to avoid any electrical issues.

2. Change Engine Oil and Filter

Steps:
1. Drain Engine Oil: Remove the oil drain plug and allow the old oil to completely drain into a suitable container.
2. Replace Oil Filter: Use an oil filter wrench to remove the old oil filter. Apply a small amount of new oil to the gasket of the new filter and install it securely.
3. Install Drain Plug: Reinstall and torque the oil drain plug to the manufacturer’s specifications (typically around 25 ft-lbs).
4. Add New Oil: Pour in the recommended grade of engine oil (consult owner’s manual) and check the level using the dipstick. Add oil as necessary.

3. Adjust Valve Clearance (if needed)

Steps:
1. Remove Valve Cover: Disconnect any electrical connectors and remove the valve cover bolts. Carefully lift the valve cover off.
2. Measure Valve Clearance: Using a feeler gauge, measure the clearance between the rocker arms and the valve stems. Check against manufacturer specifications.
3. Adjust as Necessary: If out of spec, adjust by loosening the locknut and turning the adjustment screw. Re-tighten the locknut and recheck clearance.
4. Reinstall Valve Cover: Clean the mating surface, apply a new gasket, and secure the valve cover with bolts to the specified torque.
