How can you tell if your PCV System is working? 

This Question of the Week comes from a number of questions that we received after last week's video.
How can you tell if your PCV system (positive crankcase ventilation) is working properly?
It is a seemingly simple question, but it can certainly get complicated quickly. But there are a couple of obvious things to look for that will give you a good indication about how your PCV system is functioning.
And what if you have something like a Radium Catch Can, or IAG Air Oil Separator installed?
Should you look for the same indicators to make sure that it is working properly with your PCV system?
And when and why would you want to consider installing a catch can or AOS?
We talk about all of these questions in the video this week.
Thanks for watching and Stay Tuned!
