Do you have to order the PVC valve that goes from the oil fill to the UIM from Mazda, or is it pretty much just a standard PVC valve you can pick up from NAPA or something? If you can get it at NAPA or something like that, does anyone know the part number?

 

They all funtion the same. If you have one the same size, it'll work fine.

Chances are you could use one from another mazda car also.. Many of the wiring harness plugs are interchangeable, so I'd imagine this could be too.

 

The PCV you need is better to get from Mazda. When you think about it, you not only produce vaccume, but you put out at least 8pis of boost. Most standard PCV's will fail to work after a few days, I speak from experience.
