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 to prevent any electrical issues.

2. Check and Replace Oil

Check Oil Level: Remove the dipstick, wipe it clean, then reinsert and check the oil level.
Replace Oil:
1. Drain the old oil using a socket set to remove the oil drain plug.
2. Replace the oil filter with a new one using an oil filter wrench.
3. Reinstall the drain plug and tighten to the manufacturer’s torque specifications (typically around 20-25 ft-lbs).
4. Pour in the correct type and amount of new oil (refer to the owner's manual for specifications).

3. Inspect and Replace PCV System

PCV Valve Inspection:
1. Locate the PCV valve and hoses.
2. Remove the PCV valve and check for blockages or damage.
3. Replace the PCV valve if necessary.
Hose Inspection: Check hoses for cracks or leaks and replace if required.

4. Address Oil Leaks

Identify the source of any oil leaks found during inspection.
Tighten or replace any loose or damaged gaskets, seals, or bolts as necessary.

5. Test Drive and Monitor

Reconnect the battery.
Start the engine and let it idle for a few minutes.
Monitor oil level and check for new leaks after a short test drive.
