Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to ensure safety.
Raise the vehicle using a jack and secure it with jack stands.

2. Inspect and Replace PCV Valve

Locate the PCV valve on the engine (usually near the valve cover).
Remove the PCV valve by twisting it counter-clockwise.
Inspect for blockages; replace if necessary.
- Tools Required: Pliers, socket set.
- Parts Required: New PCV valve (if faulty).

3. Address Oil Leaks

Use a cleaning solvent to clean any oily areas on the engine.
Inspect and replace any worn gaskets or seals that are leaking oil.
- Remove the oil pan or valve cover if necessary for gasket replacement.
- Tools Required: Gasket scraper, torque wrench.
- Parts Required: New valve cover gasket, oil pan gasket, or any other relevant seals.

4. Perform Engine Overhaul (if needed)

If compression test results indicate low compression, consider a rebuild or replacing piston rings.
Remove the engine head and inspect piston rings and cylinder walls for wear.
- Replace piston rings and reassemble with new gaskets.
- Tools Required: Torque wrench, engine hoist, socket set.
- Parts Required: New piston rings, head gasket, and any other worn components.

5. Change Engine Oil

Drain the old oil and replace it with high-quality oil that meets manufacturer's specifications.
Replace the oil filter as part of this procedure.
- Tools Required: Oil filter wrench, oil drain pan.
- Parts Required: New engine oil (5W-20 or as specified), new oil filter.
