Beck/Arnley Pcv Valve - 045-0253 | Smooths a rough idle and stops oil leaks and whistle from a stuck PCV valve; direct-fit OE replacement.

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

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

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.

I never write bad reviews but this one had to be written. If you’re about to put this in for your PCV valve on your Na Miata 90-97, go somewhere else. Regardless what anyone else says in this review section just trust me. It was fairly difficult to install but once it was on it broke immediately when you try to fit the PCV valve. If you still decide to get it, go ahead. Just know this product is cheap plastic and if it gets stuck in your grommet, have a good time… View pictures

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

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.

Broke pretty easily

This paired with the grommet Beck and Arnley sell fixed my low idle issue. Would recommend

buen producto

It a hellish experience when your 'pcv' goes on the blink. They very cheap, and once you replace on and it works, buy another and keep it in the glove box.

Bonne achat

very good quality, easy to install, great product

Qualité laisse à désirer, fuite.
