Solution

1. Preparation

Ensure the engine is cool before starting work.
Disconnect the negative battery terminal to prevent any electrical issues.
Gather all tools and parts needed for the repair.

2. Addressing Oil Leaks

Sub-step 1: If a leak is found, clean the affected area with a degreaser to remove old oil.
Sub-step 2: Replace any faulty gaskets or seals (e.g., valve cover gasket, oil pan gasket). Use a torque wrench to tighten bolts to the manufacturer's specifications (typically around 10-12 ft-lbs for valve cover bolts).
Sub-step 3: If the oil pan is leaking, drain the oil first, then remove the oil pan, replace the gasket, and reinstall it.

3. Oil Change (if needed)

Sub-step 1: Drain the old oil by removing the oil drain plug and allowing it to fully drain into a pan.
Sub-step 2: Replace the oil filter with a new one, using an oil filter wrench. Ensure the rubber O-ring is lubricated with fresh oil before installation.
Sub-step 3: Reinstall the drain plug with a torque specification of around 20 ft-lbs.
Sub-step 4: Fill the engine with the correct type and amount of oil (consult owner’s manual for specifics, typically 5W-20 for Honda Civic).

4. Final Inspection

Sub-step 1: Start the engine and let it idle while monitoring for leaks and smell.
Sub-step 2: Check the oil level once more and add oil if necessary.
