Hyundai 26740-2G000 Valve-PCV

The PCV system diverts the blow by gases from the crankcase through it's PCV valve and hose back to the intake manifold where they are burned in the engine. It consists of a hose leading from the valve cover to the intake duct, a PCV valve and a hose connecting it to the air intake plenum. The PCV valve is situated in the valve cover. Detach the hose from the valve then unscrew it from its position on top of the valve cover and finally reconnect that hose. During normal operating temperature, place your finger over either of them (i.e., hoses or opening) while idling; however when there is no vacuum present, ensure that one checks for any blocked or deteriorated hoses as well as manifold port. Finally turn off your engine and shake your PCV Valve listening for a rattle sound; If it does not rattle replace it with a new one. When purchasing a replacement PCV valve always be sure that it is meant for your specific vehicle model, engine size and compare your old valve with new one so as to ensure their compatibility with each other.
