    • Good PCV valve
Great replacement for OEM part at a reasonable cost. Works great. In my '96 Miata m edition. Would buy again many times. Good brand and good product

    • Missing spring, Bad sealing surface

I saw other bad reviews mixed with good ones, thought I'd run the gambit and see. When this Positive Crankcase Ventilation valve (PCV valve) didn't operate as a one way air valve (tested by blowing air in each direction through it) I pulled it apart to figure out why. The two plastic housings seemed to be glued together, required some force to get them apart. Here's the parts list in order of what I found starting from the engine intake side moving towards the engine valvecover (left to right in first image): 1. Light colored plastic housing half 2. Small spring 3. Metal washer 4. Metal valve core 5. Dark colored plastic housing half I see two main issues with this valve: 1. This design does not have a second spring like most PCV valves I've come across before. Usually between parts 3 and 4 in the parts list above there would be another spring intended to keep the PCV valve normally closed. The lack of this spring reduces the force between the valve core and the plastic housing, that force is what usually works alongside the force from air also pushing on the valve core to create a good seal preventing air from moving through the valve and into the crank case. 2. The seal created by the valve core and the plastic housing is well... not a seal. Note the stamped face containing lines and numbers on the end of the valve core shown in images 2 and 3. These raised features prevent the valve core from sitting flat on the inside surface of the plastic housing thus allow air to pass right on by. I tried 3 things to see if I could improve this design: 1. Adding oring between valve core and plastic housing made some difference but did not fix the issue 2. Filing the raised features off of the valve core made the most difference but still did not fully seal the valve 3. Adding oil inside and heating the plastic housing to 130 degrees fahrenheit seemed to make no difference What I think this valve needs: The only way I was able to get this valve to mostly seal was by filing off the raised features on the valve core and using a strong magnet to simulate the force of the aforementioned missing second spring. Even then I didn't get a complete seal but it was much better than before modification. I think this valve needs that missing spring and a better match between the sealing surfaces of the valve core and the plastic housing. Perhaps even a thin rubber washer or very soft oring to take up any imperfections. Speculation: Maybe this valve was intended to use an interior taper of the plastic housing to mostly seal around the valve core in the closed position? I can contrive a way in which worn tooling could result in that taper widening during production and no longer sealing, however I suspect such a design would stick closed quite a bit. Maybe the vacuum in the intake is enough to reliably un-stick a design like that? Sounds like an unreliable design to me based on the tight tolerance required so I'm assuming a sealing surface created by an interior taper wasn't part of the original design. Ultimately it's clear that the valve I received wasn't subjected to any testing methodology similar to my own. Despite my best speculation I haven't been able to come up with an explanation for how this design could be considered functional that doesn't include either a misunderstanding on my end or a lack of testing on the engineering/manufacturing end. ... show more

    • This pcv IS airtight, people just don't know what they are talking about.
1991 Mazda Miata Na6. I read alot of reviews about how this pcv was not airtight, and was trash basically. I ordered anyway because it's cheap, and honestly I did not believe the reviews because Beck Arney makes great stuff (IMO) when I went to install it, I did the blow test and it definitely failed. BUT! My own pcv broke in half so I had no choice. I also ordered the Beck Arney grommet, I put the grommet over the PCV valve and did the blow test again! And BAM! 100% air tight. Anyone who said it failed the blow test or is not airtight, did it without the rubber grommet over pcv. ... show more

    • Not broken -- PCV valve isn't a check valve!
I'll admit after reading the negative reviews I did my own blow test and was concerned it wasn't a one way valve. After doing my own research, I found it's not a check valve, and only needs to close for high pressure situations like a backfire. I'll blame the manufacturer for not adding a paper note in the box explaining this. I'd also recommend anyone buy from the "used like new" section, its probably a return from a misinformed person. Here's one of the examples: One way to check whether a PCV valve is functioning is to remove it from the hose or tube and shake it. If you can hear a metallic rattling noise, it's likely in good working order. If you do not hear anything when you shake the valve, it is likely that it is no longer opening and closing like it should. No one indicated it should act like a check valve. This thing certainly rattles. And it's working in my NB2 Miata. Get a new gasket when you order this. ... show more

Says beck arnley, but quality seems lower than the parts store. Valve doesn't seat well and the spring seems weaker. Either way, cheap maintenance part

Fit my 1993 Miata just fine. People that are saying it doesn't fit probably have work out hoses and grommets.
