To access it, you may need to remove any engine covers or components obstructing the valve's visibility. Always consult the vehicle's service manual for specific details and procedures.

A PCV, or Positive Crankcase Ventilation, system is designed to reduce harmful emissions from an engine by recirculating gases that escape from the crankcase back into the intake system for combustion. The PCV valve regulates this flow of gases, ensuring optimal engine performance and reducing pollution. The hose connected to the PCV valve facilitates the movement of these gases between the crankcase and the intake manifold. Proper functioning of the PCV and its hose is essential for engine efficiency and longevity.

When you open the valve, you lower the resistance in the system, allowing more fluid to flow through the hose due to increased pressure and decreased friction. Conversely, pressing on the end of the hose creates a blockage, increasing resistance and reducing the flow rate as the fluid struggles to pass through the constricted area. This change in pressure dynamics illustrates the relationship between flow, resistance, and pressure in fluid systems.
