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 shorts.

2. Inspect and Replace PCV Valve

Locate the PCV valve on the engine.
Disconnect the PCV valve hose and remove the valve.
Inspect the valve for clogs; if clogged, replace it with a new one.
Reconnect the hose securely to the new valve.

3. Address Internal Oil Consumption

If compression tests indicate low pressure, consider the following:
- Remove the intake manifold and cylinder heads if necessary.
- Inspect piston rings and cylinder walls for wear or damage.
- Replace worn piston rings and, if necessary, re-hone the cylinder walls.

4. Replace Oil Filter

Remove the old oil filter using an oil filter wrench.
Apply a thin layer of new oil to the rubber O-ring of the new filter.
Install the new oil filter, ensuring it is tightened according to manufacturer's specifications.

5. Refill Engine Oil

Use the manufacturer’s recommended oil type and fill to the appropriate level using a funnel.
Start the engine and allow it to run for a few minutes, checking for leaks.
