Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the engine is cool.
Disconnect the negative battery terminal to prevent electrical issues.

2. Drain Engine Oil

Place an oil catch pan under the oil pan.
Remove the oil drain plug using a socket wrench.
Allow the oil to completely drain into the catch pan.

3. Replace Oil Filter

Use an oil filter wrench to remove the old oil filter.
Apply a small amount of new oil to the rubber gasket of the new filter.
Install the new oil filter, tightening it by hand until snug.

4. Repair Leaking Seals

If the oil pan gasket is leaking, remove the oil pan by unscrewing the bolts with a socket set.
Clean the mating surfaces of the oil pan and engine block.
Apply a new oil pan gasket or sealant and reinstall the oil pan, tightening the bolts to the manufacturer's torque specifications (typically around 10-15 ft-lbs).
If the valve cover gasket is leaking, remove the valve cover by unscrewing the bolts.
Replace the old gasket with a new one, ensuring the surface is clean. Reinstall the valve cover.

5. Refill Engine Oil

Replace the oil drain plug and tighten it securely.
Refill the engine with the recommended type and amount of engine oil (consult the owner’s manual, typically 0W-20 for the Civic).

6. Final Checks

Reconnect the negative battery terminal.
Start the engine and let it idle; check for leaks around the oil filter and oil pan.
Monitor the oil level with the dipstick and add oil if necessary.
