Solution

1. Preparation

Gather tools and parts before starting.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the negative battery terminal to prevent electrical shock.

2. Change Engine Oil

Drain Old Oil:
- Place an oil drain pan under the oil pan.
- Remove the oil drain plug and allow the old oil to drain completely.
Replace Oil Filter:
- Use an oil filter wrench to remove the old oil filter.
- Lubricate the rubber gasket of the new oil filter with fresh oil and install it.
Refill with New Oil:
- Replace the drain plug and tighten it to the manufacturer’s torque specifications (typically around 20-25 ft-lbs).
- Add the appropriate type and amount of engine oil (refer to the owner's manual, typically 5W-20 or 0W-20).

3. Inspect and Replace Valve Train Components (if necessary)

Remove Valve Cover:
- Unscrew and remove the valve cover bolts using a socket set.
- Carefully lift off the valve cover.
Inspect Components:
- Check for worn or damaged lifters, pushrods, and rocker arms.
- Replace any damaged parts with new OEM components.
Reassemble:
- Clean the valve cover and engine surface.
- Install a new gasket, then reattach the valve cover and torque the bolts to specified values.

4. Reconnect Battery and Test

Reconnect the negative battery terminal.
Start the engine and listen for any remaining clicking noises.
Monitor engine performance to ensure the issue is resolved.
