Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to ensure safety while working on the engine.

2. Check and Change Engine Oil

Tools Required: Oil filter wrench, socket set, drain pan.
Locate the oil drain plug under the vehicle, place the drain pan underneath, and remove the plug to drain the old oil.
Replace the oil filter using the oil filter wrench, ensuring the gasket is clean and properly seated.
Reinstall the drain plug and torque to manufacturer specifications (usually around 30 ft-lbs).
Fill the engine with fresh oil, ensuring to use the correct oil type (5W-20 or as specified in the owner's manual).

3. Inspect Valve Lifters

Tools Required: Socket set, torque wrench.
Remove the valve cover by unscrewing the bolts (torque values for reinstallation should be followed as per the service manual).
Inspect the valve lifters for wear or damage, replacing any that are faulty.
Reinstall the valve cover and torque the bolts to the manufacturer's specifications.

4. Inspect Timing Chain/Belt

Tools Required: Timing tool kit, socket set.
Remove any components obstructing access to the timing cover (such as the serpentine belt and pulleys).
Inspect the timing chain or belt for wear, tension, and alignment.
Replace the timing chain or belt if it shows signs of wear or is out of specification.
