Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to ensure safety.

2. Change Engine Oil and Filter

Sub-steps:
1. Remove the oil drain plug using a socket set and allow the oil to drain completely into a pan.
2. Replace the oil filter using an oil filter wrench, ensuring to lubricate the rubber gasket on the new filter with clean oil.
3. Reinstall the oil drain plug and torque it to the manufacturer's specification (usually around 20-25 ft-lbs).
4. Fill the engine with the recommended oil type (typically 0W-20 or 5W-20) up to the appropriate level.

3. Adjust Valve Clearances

Sub-steps:
1. Remove the valve cover by unscrewing the bolts and gently prying off the cover.
2. Use a feeler gauge to measure the valve clearances; adjust them according to the specifications provided in the service manual.
3. Reinstall the valve cover with a new gasket to prevent oil leaks, torquing the bolts to the specified value.

4. Inspect and Replace Lifters (If Necessary)

Sub-steps:
1. If the lifters are suspected to be the issue, remove the intake manifold and cylinder head cover to access them.
2. Remove the lifters, inspecting them for wear or clogs; replace them if necessary.
3. Reassemble all components in reverse order, ensuring all gaskets are properly sealed.
