These modern plastic PCV valves do not rattle like the older metal PCV valves. You can hear very faint rattles if you are somewhere really quiet.

Interesting point. But as long as it has been confirmed by multiple sources, I wouldn't wage on one customer service rep's comment.
Doesn't mean that person is lying, I'd be still be cautious of installing sensitive parts that are none OEM.
Again, I had good luck with Beck/Arnley's other products but still...

It seems like a 'stupid little part' but it has a very important function. Saving a few $$$ on non-OEM parts is often a penny-wise, pound foolish decision. Especially when you DIY - you are saving so much money on labor, why not use the good parts?

Oh, I am not against using OEM parts; I think I wrote somewhere in this thread that I would stick to OEM for some crucial parts like electronics.

But some parts I think you can get away with using non-OEM parts especially when the costs are less than a half (when the difference is significant) compare to what these local Honda's are charging their customers. (These NY Honda dealers practicing extortion)
Availability is another issue I guess when you'd have to drive hours to get to local Honda OEM Parts.

I forgot which part it was but I used Beck/Arnley parts and I think I still have it on my Ody. Hence I had "good experience" using this brand.
But I cannot say t for ALL parts obviously.

I don't know specifically for these Honda PCV valves, but I've read how modern PCV systems are more complex than simple check valves. They are designed to provide specific flow resistance depending on the relative pressures on either side of the valve (manifold vacuum vs. crankcase pressure).

For me, that's enough to just get the Genuine Honda in this case.

Someone else could definitely make a check valve that rattles (or not), but it might not be flowing as Honda wants it to.

BTW, has anyone with a known good (e.g., new) Genuine Honda valve actually confirmed for themselves the clicking when doing the pinch hose B test? I did that on mine the other day, and did not get any clicking. Removed the valve and I could shake it and barely hear a little muffled rattle. So I'm having doubts about that service manual test. Anyone?

Tempted to replace it but all the posts about it breaking during removal is swaying me to leave it alone haha.

Plastic - - they break - mine did, 1 million pieces.
However, my engine performance/mpgs did improve after it replacement, so all in all it's a good move.
Just be prepared for it to break.
After you remove the 10mm bolt - - - turn it like a corkscrew to remove it - - - i tried to pry it out - - that made it worse.

I replaced mine last year with an OEM Honda unit. 50k miles. Old PCV did not rattle. New one did.

Just called local dealership and they priced it at $59.40 Cdn! Time to look around. I need to buy 2 since I got an MDX as well.

Ya we Canucks really get hosed on honda parts.
Engine mounts are 800 plus per mount.....
I don't get it........its a honda not a audi or mb.

Mounts are about the US equivalent of that at dealers here in the states, but we can usually do better if we order them online. I got mounts from BK Honda for about $400 USD last month.

We don't have any online deals.....it really sucks
They are simply charging too much for these.

Active is a fluid mount with a plunger that slides up and down.
800 is highway robbery.
Especially considering we need 2 at some point.

Doesn't BK ship to Canada? I would be surprised if they didn't but, if not, Bernardi will.

The shipping and customs charges negates any savings.....not to mention the exchange.
Trust me, that was the first place I checked.

WELL.... I broke it upon removal...

Saw this on amazon questions.

SO, I just installed it....

My 2 PVC's arrived from Rockauto today. one for the MDX and one for the Odyssey. Different part #s. Beck/Arnley and no rattling. Meh, I'll install them too. a third of the cost of the dealership one.

EDIT: a review on amazon. Based on the below, the valves I got work as described using the "blow" test so the no rattling is ok.

"This seems to be a perfectly fine product that is a valid replacement for the Honda oem pcv valve. There is lots of confusion and misinformation here, so I hope my review is helpful.

The pcv valve is supposed to be a one-way valve that allows positive crankcase vapors and pressure to be routed into the air intake and be subsequently burned in the combustion chamber. There are two openings on the valve: the holes in the middle of the valve, and the openings in the small, tip end. There is a spring loaded piston in the valve such that air should only pass from the middle holes through to the tip end.

If you can pass air both directions then the valve is no longer good (which is how my oem valve was). If you cannot pass air from the middle holes through the tip end then the valve is blocked and likewise no longer good......

THERE ARE NO LOOSE PARTS IN HERE. People saying the thing is possibly defective because they couldn't sense any parts rattling are conjecturing. Maybe that's the case for other pcv valve designs, it is not the case for this one........"

UPDATE: Currently at 145K kms. My OEM PVC came out with no issues. I checked and it rattled quite easily and seemed to be in good condition. I thought about putting it back in until I hit 200K kms but when I cleaned it up a bit and did the blow test it was letting air through in both directions so I replaced it with the new one.

The pcv valve is supposed to be a one-way valve that allows positive crankcase vapors and pressure to be routed into the air intake and be subsequently burned in the combustion chamber.

Modern PCV valves are not just simple one-way valves. They do keep air from flowing back into the crankcase, but that is actually a minor portion of its function.

This is not specific to Honda, but this is how most PCV valves work:

Basically, the valve has tuned flow to control the crankcase pressure - negative if possible, but not too negative which would suck too much oil into the intake system. Each PCV valve will be 'tuned' to the engine it is designed for. That is the reason why spending a bit extra for the Honda part is worth it.

Mine broke apart when I tried to remove it.
What a 3 hour hassle to get it out.

Plastic pic's are for one reason only....cheapness.

How did you get it out?

 

[White2015]

How did you get it out?

I had to break it apart and fish it out using a mirror and a borescope.
Bloody nightmare.
If Honda had used a metal PCV - it would have come out after 15 years.
But on a 2015 - - the plastic should not have degraded so quickly.
A very poor/cheap design

 

[ryukin2000]

....If Honda had used a metal PCV.....

I came across this when I was searching for a replacement. Doesn't look the same as OEM however so I passed on it but wish they did make it to match.

Did my PCV on weekend at 284000km with the OEM. It very easy come out and still making noise easy but new one more nosey. Should have wait bit more 320k km. Only take 5min for me.

Having a new OE PCV valve, if you're willing to do the pinch test shown earlier in this thread, you could answer the question I still have about this, from post #44 above,

"BTW, has anyone with a known good (e.g., new) Genuine Honda valve actually confirmed for themselves the clicking when doing the pinch hose B test? I did that on mine the other day, and did not get any clicking. Removed the valve and I could shake it and barely hear a little muffled rattle. So I'm having doubts about that service manual test. Anyone?"

As far as I know, I have no problems, and am still on the original PCV valve. But I do not get any click when doing the pinch test.
