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 avoid electrical issues.

2. Inspect and Repair Leaks

Tools Required: Socket set, torque wrench, oil catch pan
Inspect the valve cover gaskets and replace if leaking.
- Remove engine cover (if applicable).
- Unscrew the valve cover bolts and carefully remove the cover.
- Clean the mating surfaces and replace the gasket.
- Reinstall the cover and torque the bolts to manufacturer specifications.
Check the oil pan for leaks.
- If leaking, remove oil from the pan using the catch pan.
- Unscrew the oil pan bolts and remove the pan.
- Replace the oil pan gasket and reassemble, torquing to specifications.

3. Addressing Internal Issues

Tools Required: Compression tester, OBD-II scanner
If compression test indicates low pressure, consider:
- Replacing piston rings or valve seals.
- This may require engine disassembly, so consult service manual for specifics.

4. PCV System Inspection

Tools Required: Basic hand tools
Remove the PCV valve and inspect for blockages.
- If clogged, replace with a new valve and ensure proper installation.
