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 electrical issues during repairs.

2. Inspect and Replace PCV Valve

Remove the PCV valve from the engine.
Check for clogs by shaking it; if it doesn’t rattle, replace it.
Install the new PCV valve securely.

3. Address Oil Leaks

Identify leaking areas (e.g., valve cover gasket, oil pan gasket).
Remove the necessary components to access the leaking gaskets.
Clean the surfaces with a degreaser.
Replace the gaskets using manufacturer-approved parts and torque specifications.

4. Perform Engine Compression Test

Remove spark plugs and connect the compression gauge to each cylinder.
Crank the engine and record the compression readings.
If readings are below specifications, consider further engine repair or overhaul.

5. Add Oil Stop Leak (Optional)

If minor leaks are detected, consider adding a commercial oil stop leak additive.
Follow manufacturer instructions for application.

OBD-II scanner
Compression gauge
Socket set
Torque wrench
Degreaser
Oil stop leak additive (optional)

Parts Required:

New PCV valve
