Solution

1. Preparation

Gather tools and materials: oil catch pan, socket set, wrench, new oil filter, new engine oil, torque wrench, and gasket sealant (if needed).
Ensure the vehicle is parked on a level surface and engine is cool.

2. Change Oil Filter

Remove the old oil filter using an oil filter wrench.
Apply a small amount of new oil to the rubber gasket of the new oil filter.
Install the new oil filter by hand until snug, then tighten according to manufacturer specifications (usually 3/4 turn after the gasket contacts the surface).

3. Replace Oil Drain Plug and Oil

Place an oil catch pan under the oil drain plug and remove the plug using a socket wrench.
Allow the old oil to drain completely into the catch pan.
Inspect the drain plug for wear; replace it if damaged.
Reinstall the drain plug and tighten it to the manufacturer’s torque specification (usually around 30 ft-lbs).
Pour new engine oil through the oil filler cap, using the recommended oil type and quantity (typically 4.5 quarts for most Civic models).

4. Inspect and Replace Gaskets/Seals

If leaks are found at the valve cover gasket, remove the valve cover by unbolting it carefully.
Clean the mating surfaces and apply gasket sealant if required.
Replace the valve cover gasket and torque bolts to manufacturer specifications.
If the oil pan or main seals are leaking, remove the oil pan or transmission components as needed, replace the gaskets/seals, and reassemble.
