Solution

1. Preparation

Tools Required: Oil catch pan, socket set, torque wrench, rags, OBD-II scanner.
Safety Warnings: Disconnect the battery before working on electrical systems, allow the engine to cool before inspection.

2. Addressing Oil Leaks

Inspect and Replace Valve Cover Gasket:
- Remove the engine cover if applicable.
- Unscrew the valve cover bolts using the socket set.
- Carefully lift the valve cover off and inspect the gasket.
- Clean the mating surfaces thoroughly.
- Replace the old gasket with a new one.
- Reinstall the valve cover and torque the bolts to manufacturer specifications (usually around 7-10 ft-lbs).
Check and Replace Oil Filter:
- If the oil filter is leaking, use an oil filter wrench to remove it.
- Apply a small amount of new oil to the rubber O-ring of the new filter.
- Install the new filter and tighten it securely.

3. Addressing PCV System

Inspect and Replace PCV Valve:
- Locate the PCV valve, usually on the valve cover.
- Disconnect the PCV valve from its hose.
- Remove the old PCV valve and install a new one.
- Ensure that the hose is properly connected.

4. General Maintenance
