Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and allow the engine to cool.
Disconnect the negative battery terminal to prevent any electrical issues.

2. Inspect and Replace Gaskets

Valve Cover Gasket:
- Remove the engine cover if applicable.
- Unbolt the valve cover using the socket set.
- Carefully lift the valve cover and remove the old gasket.
- Clean the mating surface of the valve cover and cylinder head with a scraper.
- Install the new gasket and reattach the valve cover, torquing the bolts to manufacturer specifications (approximately 7-9 ft-lbs).
Oil Pan Gasket:
- Drain the engine oil using an oil pan and remove the oil drain plug.
- Unbolt the oil pan using the socket set.
- Remove the old oil pan gasket and clean the surface.
- Apply a new gasket and reattach the oil pan, ensuring to torque to manufacturer specifications (approximately 10-12 ft-lbs).

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 by hand, tightening it until it is snug.

4. Replace Seals (if needed)

If the crankshaft seals are leaking, remove the crankshaft pulley using a puller tool.
Replace the front and/or rear crankshaft seals, ensuring they are seated properly.
Reinstall the crankshaft pulley and torque to manufacturer specifications.

5. Refill Engine Oil

Replace the oil drain plug after reassembling the oil pan.
Refill the engine with the appropriate type and amount of engine oil (typically 5W-20 for Honda Accord).
Reconnect the negative battery terminal.
