Solution

1. Preparation

Gather tools and parts required for the repair.
Disconnect the negative battery terminal for safety.

2. Identify and Repair Leaks

Valve Cover Gasket Repair:
- Remove the engine cover (if applicable) using a socket set.
- Unbolt the valve cover and carefully lift it off.
- Clean the mating surfaces with a lint-free cloth.
- Replace the old gasket with a new one, ensuring it is seated properly.
- Reassemble the valve cover, tightening bolts to the manufacturer’s specified torque (usually around 7-9 ft-lbs).
Oil Pan Gasket Repair:
- Raise the vehicle and secure it on jack stands.
- Drain the engine oil and remove the oil pan.
- Clean the surfaces and replace the old gasket.
- Reinstall the oil pan, tightening bolts to the specified torque (typically around 10-12 ft-lbs).

3. Replace PCV Valve (if necessary)

Locate the PCV valve, which is usually on the valve cover.
Remove the old PCV valve and replace it with a new one.
Ensure the grommet is in good condition and seated properly.

4. Refill Engine Oil

After repairs, refill the engine with the correct type and amount of oil (usually 5W-20 for the Honda Accord).
Start the engine and let it run for a few minutes to circulate the oil.
