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 any electrical issues during repair.

2. Change Engine Oil and Filter

Remove the oil drain plug using a socket set and let the old oil drain completely.
Replace the oil filter using an oil filter wrench.
Reinstall the drain plug and tighten to the manufacturer’s torque specification (usually around 25 ft-lbs).
Add fresh engine oil (refer to the owner’s manual for the correct type and amount, typically 0W-20).

3. Inspect and Replace Engine Components

If knocking persists, inspect the timing chain/belt tensioner and replace it if worn or damaged.
Check the oil pump for proper operation and replace if faulty.
If the noise is from the bottom end, remove the oil pan and inspect the connecting rod bearings for wear; replace if necessary.

4. Reassemble and Reconnect

Reinstall any components that were removed for inspection or replacement.
Reconnect the battery and ensure all electrical connections are secure.
