In our last two posts we took a look at the prototype catch can brackets and hoses for both the driver and passenger-side. As a recap and to better explain our results, the next paragraph describes the crank case ventilation systems on the Mustang GT. If you're not in a reading mood feel free to continue to the results below.
Crank Case Ventilation on the Mustang GT
While we can continue to refer to the two catch can systems as the driver and the passenger-side, we can also differentiate them another way. This will allow us to better understand the results of our testing. The passenger-side catch can is tapped into the ventilation line that allows crankcase air (and blow-by) to exit the engine. We often call this the positive crankcase ventilation, or PCV line. This line is equipped with a valve, referred to as the PCV valve, which works to regulate the air flowing through the crank case ventilation (CCV) system. The driver-side catch can is tapped
