Broken Intake Resonator
 
I wash checking my drop-ins and noticed this, on driver's side:
https://cimg6.ibsrv.net/gimg/www.myg...d808b7ee7e.jpg

Looks like the PVC piping on the bottom of the resonator is broken...

I wouldn't be concerned, but it looks like this piping feeds into the top of the block or cylinder head?
(sorry, best pic I could get with my bad camera & light)
https://cimg7.ibsrv.net/gimg/www.myg...d0f6fbf368.jpg

Hard to tell from the pics, but it looks like there was some adhesive applied there (yellow/white blob).
Maybe a glue or epoxy. I'm wondering if this was broken previously and glued back together by previous owner or shop.

I put the silicone intake tubes in, but it seems unlikely to me that the small change in angle from the stock intake tube could shear the piping like this.
Thoughts?
Should I be concerned with particles being sucked into the motor?

I'll look for a replacement.
From what I can tell, it's component #20 in the diagram... "PVC pipe"
https://cimg7.ibsrv.net/gimg/www.myg...b05ca3a3e8.png

Can anyone confirm for me if I have this correct or not?
Recommendations on best place to find a OEM replacement that's not ridiculous dealer priced?

Or maybe this is a good chance to make an upgrade to... I don't know?

Appreciate any insights!

Update:
Looks like McStealth had this near exact same question in 2016...
https://www.myg37.com/forums/intake-...-needed-2.html

Outcome = undecided

From my reading, this is part of the PCV System, cycling air (pressure) from the crank case back into the intake.
It's a bit of an odd component, that seems to exist between the PCV and Intake Systems.
There is a hose from the Rocker Cover to the underside of the resonator, where the break is, and another from the top side of the resonator to the Intake ("Air Cleaner" as they call it)
(PCV Diagram: https://www.infinitipartsdeal.com/pa...agram=118_C002)
(Intake Diagram: https://www.infinitipartsdeal.com/pa...agram=165_C004)

It seems Infiniti does not sell this (stupid) plastic box individually, but instead as a part of the complete "Air Duct" assembly.

A bit ridiculous if you ask me. It's a simple, plastic box.
2 clamps and I could swap it in 30 seconds.

It happened to me a week ago when I was cleaning my throttle bodies - It's very fragile, a gentle push broke the PCV pipe - Looked everywhere to find the part without any luck - Every shop that I checked was trying to sell it with the intake tube.

So I ordered the EPS tuning PCV delete kit and installed that instead. Looks much better and I think it's a good upgrade when you're in this situation

G.AWD.zilla 11-14-2019 05:38 PM

It's always these tiny things that drive me nuts.

Yeah, trying to decide which way to go without wading into the PCV Delete vs Oil Catch Can debate.

I did a lot of research, I think the PCV delete is OK if you are NA and not supercharged/turbocharged - Plus the catch can system is expensive

G.AWD.zilla 11-14-2019 05:46 PM

Thanks man, for the feedback.

That's my understanding as well.
Worse comes to worse, can always swap the breathers if they seem to be oil-soaked I suppose.

G.AWD.zilla 11-14-2019 05:47 PM

... of course that would imply bigger problems

My
.02 cents. If you have kids a wife or value your health do not do pcv delete atleast to atmosphere because these are straight gas fumes that enter the cabin. To me 10x worse than test pipes. I did it and instantly regretted it. So that little piece is hollow inside. Literally nothing. So a 3 way pipe or t fittings is all that's needed to keep things happy.

G.AWD.zilla 11-14-2019 10:03 PM

Thanks for the insight. I'm still hoping to find an OEM part for now, but might end up doing some home fabricating if it comes to that.

I might have my OEM one laying around if you're interested. Shoot me a PM.

with the hole in the system you will probably get a CEL at some point when the system does a check, maybe after 500-1000miles/kms or something..probably gonna be a P4XX code, it may cause a lean condtion if the system tries to compensate...for the unmetered air entering post MAF

You can delete the PCV system (go catchcan/open or closed loop etc...) but you can also just bridge that connection (the little box is just a resonator) with some standard PCV hose to reseal the system...or you can put up a WTB in the classifieds I'm sure lots of ppl have oems lying around

I had the same/similar problem with alignment with my HPS intakes BTW. the Driver side caused major alignment issues...you can trim the HPS pipe at the TB on a bit of an angle and it will change the angle of the whole pipe giving more clearance to those PCV pipes..use a very sharp blade, put some painters tape on the outside and brace against something stiff inside the pipe to get a clean cut

Would something like this work, do you think?

yeah, if its the right diameter (not sure about it) should work throw some hose clamps on it and it should hold...

Came up with a fix over the weekend:
https://cimg8.ibsrv.net/gimg/www.myg...b7d10105b4.jpg

https://cimg8.ibsrv.net/gimg/www.myg...5ff4188ee1.jpg

Total cost: $0.65
Seems to be holding up for now. Will keep an eye on it and report back after some more miles.
May end up going back to OEM if I feel it necessary.

Thanks all for the help!

Wheres the house from the other side plugin? That hose from otherside is to help equalize pressure between the two banks.

Edit looks like VHR has separate pcv systems vs single on my HR sedan. Carry on. Good fix.

G.AWD.zilla 11-18-2019 03:21 PM

Sorry. Not sure I'm following your question.

There were only 2 hoses:
1 from rocker cover to the resonator
1 from resonator to Intake

Both are still intact, never removed.

You talking about a different hose?

From what I see your little box that broke has two openings?
On my HR I have 3. One to valve cover one to intake pipe and one that has a long hose connected to the other side intake pipe. Looks like a different setup from HR to VHR. that's why I initially said a T fitting.

Well I'll be.. that is different. Interesting.

Yep, only ever had 2.

Wonder why you have 3...

The HR has only one pcv system so that third is to equalize pressure between the two. Since you have two pcv valves you dont need a hose connecting the two banks.

Just snapped mine off today too replacing both PCVs...... Going tomorrow to try the elbow.
