Solution

1. Preparation

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

2. Oil Change

Drain Old Oil
- Place a drain pan under the oil pan.
- Remove the oil drain plug using a socket set.
- Allow the oil to drain completely.
Replace Oil Filter
- Locate and remove the oil filter using an oil filter wrench.
- Apply a thin layer of new oil to the rubber gasket of the new filter.
- Install the new oil filter by hand until snug, then tighten it slightly (do not over-tighten).
Add New Oil
- Replace the drain plug and torque it to the manufacturer’s specifications (typically around 20-30 lb-ft).
- Use the recommended oil type and capacity (5W-20 typically for Honda).
- Pour the new oil through the oil filler cap.

3. Inspect Engine Components

Valve Adjustment
- If necessary, remove the valve cover.
- Inspect and adjust the valve clearance according to manufacturer specifications.
- Reinstall the valve cover with a new gasket if required.
Check Timing Components
- Inspect timing chain/belt for wear or damage.
- Ensure tensioner is functioning correctly and adjust if necessary.

4. Final Checks

Reconnect the battery.
Start the engine and listen for any remaining noise.
