Solution

1. Preparation

Gather necessary tools and parts.
Ensure the engine is cool and the vehicle is safely parked on a level surface.
Disconnect the battery if necessary for safety.

2. Inspect and Tighten Components

Oil Filter:
- Use an oil filter wrench to check if the oil filter is properly tightened.
- If loose, tighten it according to manufacturer specifications (typically hand-tight plus a quarter turn).
Drain Plug:
- Use a socket wrench to check the drain plug's tightness.
- If loose, tighten to the specified torque (typically around 20-25 ft-lbs for most Honda models).

3. Replace Damaged Parts

Oil Filter Replacement:
- If the oil filter is damaged or not sealing properly, replace it with a new filter.
- Apply a thin layer of clean oil to the rubber gasket of the new filter before installation.
Drain Plug Gasket:
- If the drain plug gasket is damaged, replace it with a new one.
- Ensure the new gasket is properly seated before reinstallation.

4. Clean Up and Refill

Clean any spilled oil from the engine bay or undercarriage with an oil absorbent.
Refill the engine with the correct type and amount of oil as specified in the owner’s manual.
