The PCV Hose channels harmful exhaust fumes from the crankcase back to the intake for prevention of constant engine misfire. The PCV Hose acts as a flexible connecting device between the crankcase and spring-loaded PCV valve, directing vapor measured by the valve's sliding pintle. In its unbroken state, the flow avoids creation of pressure, confirms a correct air-fuel mix, and assists the catalytic systems of the various Nissan models to meet clean-air rules. When a PCV Hose cracks, it breaks the seal, thereby letting unmeasured air get inside, letting the engine run rough and burn extra fuel. Throughout the various Nissan Quest generations, the basic design of the PCV Hose has remained unchanged; an uncomplex piece of molded rubber or plastic tubing that comes in driver-side or passenger-side routing. However, when buying a replacement, there are two fit options. Direct-fit pieces are shaped exactly like the factory tube so they drop right into place. The other option is a universal line, which requires trimming. The main difference is the precision since the direct-fit style clips into the factory clamps without needing extra tools. Nissan owners frequently change the Quest PCV Hose during regular maintenance of the air filter to keep their Quest running smoothly as this little piece is inexpensive and easy to swap.
