2. Replace PCV Valve

Sub-steps:
1. Locate the PCV valve on the engine (consult the service manual for exact location).
2. Disconnect any hoses attached to the PCV valve.
3. Remove the old PCV valve by twisting it out of its socket.
4. Install the new PCV valve by pushing it into the socket until it clicks into place.
5. Reconnect the hoses securely.

3. Inspect and Replace Engine Seals/Gaskets

Sub-steps:
1. Identify the seals and gaskets that may be leaking (e.g., valve cover gasket, oil pan gasket).
2. Drain the engine oil and remove any necessary components to access the gaskets.
3. Remove the old gaskets and clean the surfaces thoroughly to ensure a good seal.
4. Install new gaskets using the manufacturer's recommended sealant if needed, ensuring they are aligned properly.
5. Reassemble components and refill engine oil to the appropriate level.

4. Perform Engine Tune-Up

Sub-steps:
1. Replace spark plugs if they show signs of wear or oil fouling.
2. Inspect ignition coils and replace any that are malfunctioning.
3. Clean or replace the air filter to ensure optimal air intake.
