Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is cool.
Disconnect the battery to prevent electrical shocks.

2. Inspect Engine Components

Tools Required: Socket set, torque wrench, flashlight.
Remove the engine cover by unscrewing the bolts and lifting it off.
Inspect the valve train components (rocker arms, lifters) for wear or damage.
Check the timing chain or belt for proper tension and condition.
Re-torque any loose bolts to manufacturer specifications using a torque wrench.

3. Change Engine Oil and Filter

Tools Required: Oil filter wrench, drain pan, funnel, socket set.
Drain the old engine oil by removing the oil drain plug and allow it to fully drain into the pan.
Replace the oil filter using an oil filter wrench.
Reinstall the drain plug once the oil has drained completely.
Fill the engine with the appropriate grade of oil (refer to the owner's manual) using a funnel.

4. Reassemble and Test

Reinstall the engine cover and tighten all bolts securely.
Reconnect the battery.
Start the engine and listen for the clicking sound while checking for leaks.
