Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Allow the engine to cool before working on it.

2. Drain Engine Oil

Tools Required: Oil catch pan, socket set, wrench.
Place the oil catch pan under the oil pan.
Remove the drain plug using the socket set, allowing the old oil to drain completely.
Replace the drain plug and torque it to the manufacturer's specifications (usually around 20 ft-lbs).

3. Replace Oil Filter

Tools Required: Oil filter wrench.
Locate the oil filter and use the oil filter wrench to remove it.
Apply a small amount of new oil to the rubber gasket of the new oil filter before installation.
Install the new oil filter by hand and tighten it until snug (do not over-tighten).

4. Address the Leak Source

Identify the source of the oil leak based on the diagnostic steps.
If the valve cover gasket is leaking:
- Remove any components obstructing access to the valve cover.
- Unscrew the valve cover bolts and remove the cover.
- Clean the mating surfaces and replace the gasket. Reinstall the valve cover and torque the bolts to specifications (usually around 7-9 ft-lbs).
If the oil pan gasket is leaking:
- Support the engine with a jack and remove any components blocking access to the oil pan.
- Unbolt the oil pan and carefully remove it.
- Clean the mating surfaces, install the new gasket, and reattach the oil pan. Torque the bolts to specifications (usually around 10-12 ft-lbs).

5. Refill Engine Oil

Tools Required: Funnel.
Remove the oil filler cap and pour in the new engine oil using the funnel.
Use the recommended oil type (typically 0W-20 for Honda Civics).
Replace the oil filler cap after refilling.
