PCV Valve, 84-89 300ZX Turbo
Part #:18-9054
Price: $5.14
See Description.
Supercedes to 18-9050.
Description:
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 builds 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. We recommend inspecting this valve at every tune-up and replacing as needed.
PCV Valve Location:
Located on the right (passenger) side of the intake collector. It points out toward the right side of the car and is roughly centered front to back. The hose runs from the passenger side valve cover up to the valve.
Supercessions:
This part number is 'superceded'. Most of our supercessions originated with Nissan. A part made for a Z31, for instance, may actually be the same as the part made for the Z32, but it was given a different number. Nissan would then later supercede the number, so that if you ordered the part number for the Z32, what you would actually get is the original part number for the Z31 (or vice-versa), as they are the same part. Other times, supercessions can exist between different parts on the same car, as is often the case with hardware of the same size. These supercessions were Nissan decisions, where replacing the 'superceded from' part with the 'superceded to' part results in identical performance. The vast majority of them are simple numbering changes, where the parts are literally identical. In some cases, the two parts are identical in fit and function, but the finish is slightly different, or the non-critical overall dimensions are slightly different (like one starter housing being '' shorter than the other on the non-attached side). They do not affect the function of the part, and in many cases, the 'superceded-to' part improves upon the 'superceded-from' part.
