Trying to locate an oil leak I removed the plastic engine covers. I noticed a small valve type unit with an outlet next to the oil filler cap.

A bit of research I found this is a Crankcase Pressure Regulator Valve.

Is this something that should be regularly replaced as part of routine service?

Also, what are the symptoms when these fail?

Trying to get familiar with my new car.
