Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to prevent any electrical shorts.

2. Identify and Repair Oil Leaks

Sub-steps:
1. Remove any engine covers if necessary using a socket set.
2. Clean the affected areas with engine degreaser to identify the source of the leak.
3. Replace damaged components (e.g., valve cover gasket, oil filter) as necessary.
4. Reassemble any removed parts and reconnect the battery.

3. Change Engine Oil

Sub-steps:
1. Raise the vehicle using a jack and secure it with jack stands.
2. Place an oil catch pan under the oil pan and remove the oil drain plug using a socket wrench.
3. Allow the old oil to completely drain, then replace the drain plug and torque it to manufacturer specifications (typically around 20-25 ft-lbs).
4. Remove the old oil filter with an oil filter wrench and install a new filter, applying a bit of new oil to the gasket to ensure a proper seal.
5. Refill the engine with the appropriate type and amount of new engine oil (typically 0W-20 for Honda Accord).

4. Test for Proper Operation

Sub-steps:
1. Start the engine and allow it to reach operating temperature.
2. Inspect for leaks around the repaired areas.
3. Take the vehicle for a short test drive and monitor for any unusual smells or smoke.
