What Is a PCV Valve and What Does It Do?

If you’re wondering what that little valve is next to your engine and what it does, you’re not alone. PCV valves are often overlooked but they play an important role in keeping your engine running smoothly. The Positive Crankcase Ventilation (PCV) valve allows gases from the crankcase to be vented to the atmosphere while preventing outside air from entering the crankcase. This helps to prevent pressure build-up in the crankcase, which can lead to oil leaks and engine damage. So next time you take a look at your engine, make sure you know what that PCV valve is for!

Who invented PCV Valves?

Did you know that the PCV system was invented by none other than Charles Kettering, of Dayton, Ohio? He’s also responsible for inventing the electric starter and leaded gasoline. Talk about a man ahead of his time! PCV valves were first used on production cars in the 1960s and they’ve been helping to keep engines running smoothly ever since. So next time your car is running a little rough, make sure to check it and give it a good clean if necessary. A little TLC now can save you a lot of money down the road.
