Factory PCV Valve, 09-19 370Z

Factory PCV Valve, 09-19 370ZQuantity in Basket:none
Code: 18-9057

A properly functioning Positive Crankcase Ventilation (PCV) system is critical to the life of your engine. It draws fresh, filtered air from the air filter through the block in order to remove harmful gasses and moisture that build up in the form of condensation as the engine cools down; moisture that would otherwise damage both internal components and the block itself over time. This system uses manifold vacuum to remove these harmful contaminants and sends them to the intake to burn with the fuel mixture. The PCV Valve is the main functional component of this system: its job is to regulate airflow through the system and prevent any sort of backflow into the block. Depending on how it failed, the valve can cause a few different symptoms, ranging from running lean/rich to excessive moisture in the oil. A faulty valve is also one of the common causes of oil seepage from the valve cover and excessive oil consumption; two common issues with the VQ engine type! A tune up is the ideal time to replace the PCV valve on older cars; however, on newer cars we generally recommend inspecting the valve every 15k-30k miles. Cleaning the valve can help prolong its life, but eventually the internal components will wear out and require replacement. Sold individually, 2 required per car. This is the genuine, original equipment (OEM) replacement. Insulator o-ring not included; see Related Items below.

PCV Valve Location:
Unlike earlier model Z-Cars, the PCV Valves on the 370Z are installed directly into both valve covers, towards the front of the engine. The PCV hoses fit on the valves and run to the intake plenum. (Older model Z's have the valve on the manifold end of the hose instead.)

Installation Note:
Keep in mind that the valve covers on the 370Z are plastic, and that the PCV valves are threaded in. It will be very easy to damage the threads on the valve cover or worse if overtightened. We recommend installing the new valve by hand and finishing with an inch-pound specific torque wrench. Torque Spec: 22 in-lb. Don't forget to lubricate the o-rings with new engine oil prior to installation.
