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 prevent any electrical shorts.

2. Change Engine Oil

Remove the oil drain plug using a socket set and allow the old oil to drain completely into a pan.
Replace the oil filter using an oil filter wrench.
Install a new filter according to manufacturer specifications.
Reinstall the drain plug with a torque wrench to the specified torque (consult the service manual for exact torque values).
Refill the engine with the recommended oil type and quantity.

3. Inspect and Replace Timing Components (if necessary)

Remove the engine cover by unscrewing the bolts.
Check the condition of the timing chain/belt and tensioners. If worn or damaged, replace them.
Reinstall the engine cover and secure it with the specified torque settings.

4. Tighten or Replace Engine Mounts (if applicable)

Inspect engine mounts for cracks or deterioration.
If any mounts are damaged, remove the bolts securing the mounts using a socket set.
Replace with new mounts and tighten to the manufacturer’s specifications.

5. Reconnect Battery and Test

Reconnect the battery terminals.
Start the engine and listen for the knocking sound; observe if it persists.
