Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Check Oil Level

Remove the dipstick and clean it with a cloth.
Reinsert the dipstick fully and remove it again to check the oil level.
If the oil level is low, top up with the correct oil type as specified in the owner’s manual.

3. Inspect Oil Filter

Locate the oil filter and check for any signs of leakage.
If the filter is loose, tighten it to the manufacturer’s specifications.
If damaged, replace the oil filter:
1. Use an oil filter wrench to remove the old filter.
2. Apply a small amount of new oil to the rubber gasket on the new filter.
3. Install the new filter by hand, then tighten it an additional 3/4 turn.

4. Check for Proper Oil Type

Confirm the oil used during the change matches the manufacturer’s specifications (e.g., SAE 0W-20 for most Toyota models).
If incorrect oil was used, drain the oil and replace it with the correct type:
1. Remove the drain plug using a socket set.
2. Allow the old oil to fully drain into a pan.
3. Replace the drain plug and torque it to the specified value (typically around 25-30 ft-lbs).
4. Refill the engine with the correct oil type through the oil filler cap.

5. Inspect Engine Components

Visually inspect the engine for any loose connections or damaged components.
Tighten any loose bolts or mounts that may contribute to noise.
If necessary, remove any covers to inspect for internal damage.

6. Reconnect Battery and Test

Reconnect the negative battery terminal.
Start the engine and listen for the knocking noise.
Monitor oil pressure and temperature gauges.
