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 before starting work.

2. Addressing Oil Leaks

Locate the Leak: Use a UV dye and black light if necessary to pinpoint the source of the leak.
Repair or Replace:
- If the leak is from a gasket (e.g., valve cover, oil pan), replace the gasket with a new one.
- Use a torque wrench to tighten to manufacturer specifications (usually 7-9 ft-lbs for valve covers).
- If the leak is from seals, replace as needed.

3. Replacing the PCV Valve

Remove the Old Valve: Locate and disconnect the old PCV valve from the intake manifold.
Install the New Valve: Place the new PCV valve in the same position and secure it.

4. Engine Oil Change

Drain Old Oil: Remove the oil drain plug and allow the old oil to completely drain.
Replace Oil Filter: Remove the old oil filter using an oil filter wrench, lubricate the gasket of the new filter, and install it.
Add New Oil: Reinstall the drain plug and add new oil (5W-20 recommended) to the engine, following the manufacturer's specifications.

5. Final Inspection

Check for Proper Operation: Start the engine and let it run for a few minutes. Check for any leaks around the repaired areas.
Monitor Oil Level: After a week of driving, check the oil level to ensure it’s within the normal range.
