Solution

1. Preparation

Gather tools and parts required.
Ensure the engine is cool and the vehicle is parked on a level surface.

2. Check and Replace PCV Valve

Locate the PCV valve, typically found on the valve cover.
Disconnect the PCV hose from the valve.
Remove the old PCV valve by twisting it and pulling it out.
Install the new PCV valve by pushing it into place until it clicks.
Reconnect the PCV hose securely.

3. Address Oil Leaks

Identify the source of the oil leak (gaskets, seals, oil filter).
For leaking gaskets, remove the old gasket material and clean the surface.
Install a new gasket with the appropriate torque specifications.
Replace any faulty seals and ensure the oil filter is tight and not leaking.

4. Perform Engine Compression Test

Remove the spark plugs for easier access.
Insert the compression tester into each cylinder's spark plug hole.
Crank the engine a few times while monitoring the gauge.
Compare the readings to manufacturer specifications, noting any low values.

5. Adjust Oil Change Frequency

If oil consumption is excessive, consider changing the oil more frequently.
Use high-mileage oil if the vehicle has significant wear.
