The simple tool below is used for checking the PCV System. With the engine idling and the oil fill cap removed, this is placed on the fill hole for a go/no go indication.
You can also just place the palm of your hand over the fill hole or a strip of paper. There should be a slight vacuum felt.
If there is smoke coming out the fill hole, the PCV is not working or there is way too much blow-by for the PCV system to handle

Wow, i’ve never seen a tool like that before?! Where in the world did you acquire that, looks like something from the 70s! What you say for testing the system and having a slight vacuum in the crank case is correct. The blow by pressure can be the cause of oil leaks at various points on the engine as well. Typical on a high mileage worn out motor.
