Air filter foam went through intake.

[Vtur]

That filter doesn't have the aluminum screen mesh on top like factory's filter. It provides rigidity and preventing it from collapsing. I think the IC probably caught most of that blue prefilter foam though.

Questions - why is that filter so distorted and contorted? They should lift right out and lay flat after removed.

The foam is a "pre-filter" and should face down - how could it get up into the top and sucked into the intake? Only if the filter didn't seal properly, IMO

Any other diesel JT owners wanna comment on my take?
It's the same sort of assembly on gas, air comes into the bottom box, moves upward, through the foam first, then through the paper, and if the paper part is sealed correctly in the box, the foam would be stopped like any other dirt.

Am i really off-base here - doesn't that thing look really distorted like it missed the seal area?
Something just doesn't seem right here.
I can install and remove the same filter over and over and over and not have it twisted up at all.
So my question - is the diesel that hard to get a filter out of or into?
Come on, diesel guys...........

As soon as I read his post was thinking no way that can happen. Think he’s stating cigarette reports when he mentioned soot and “tar” was all he found lol

It will have to go through the turbo first then the intercooler before reaching the inlet manifold.

I started noticing erratic behavior when in a rainstorm about 2 months ago. (service throttle etc.)

After seeing what looks like a wet filter (or the aftermath of one) this kinda sounds like "I splashed through puddles because it's a jeep and it's made to do this".

Turbo may have had a snack and then puked it into the intercooler. Any detritus would have been stopped at the intercooler. Pull the intercooler inlet and see if anything is in there.

You are correct I have 4 ecodiesel never had one do that ? Something had to eat the foam mouse ,squirrel, etc... I did have a Cummins in my Prevost suck a filter up like that but a critter built a nest in the bottom over the winter.

BINGO

That sucks!!!!! These ecodiesels really suck air…

I’m betting weak filter frame, wet filter, wet edges to the filter, created the ‘perfect storm’

I just ordered an s&b intake with (dry filter) and a pre filter. Because Mopar filters are expensive and hard to source at times.

if I was keeping intake stock at this point, I’d also only run Mopar filters.

I would also be looking at the intake side of the inter cooler, as I bet most of the material is there.

Do the ecodiesel community a favor and post those pictures on Amazon…. Lots of these filters are sold over there…. Many owners do not know….

I hear what you're saying - but was it REALLY the filter, or installation, or a reason it did that when it otherwise would never do that?
Blame the filter for being soaked, or for a mouse/chipmunk nest or install issue?
Could be, but the whole story isn't visible.

This time of year - mice or other critters are hauling stuff into dark secluded places to make a comfy nest with food at hand.
If it didn't get wet (and I sort of wonder if anyone would admit to that anyway) then it's very possible that space under the filter itself, in the box, was a nest with chewed up foam, grass, twigs, maybe around here there'd be acorns and corn and sunflower seeds in there.
That baby need to take a deep breath and all of a sudden - there's more pull than the thing can stand.
Still if that filter was clamped tight between box and top, all screws tight, it would have to be really plugged or something amiss.
It's another one of those "I can't see it to really know the whole story or the rest of the story". But i prefer to find "root cause" or what actually caused it to let loose and not right away say "filter was to blame".
Maybe, maybe not. There's possibly stuff we'll not know. But that filter box is meant to clamp down against that seal. The filter had to be really plugged with something - water or debris, etc.

That filter looks like it got real wet and the vacuum from the engine caused it to collapse. That would explain the foam issue.

Yes, it would. It had to be really wet/plugged to pull it out of the grip of the top of the air box.
That's all I can figure.
Maybe the mousies had a bit of a party in there, a bit much beer and they were seeing who could pee up onto the filter.

.... Good luck with that warranty claim

 

[ShadowsPapa]

The jeep is under warranty, and I'm bringing it to the dealer tomorrow.

I've never seen such a thing and I have changed a lot of air filters. Because of this a lot of snow/dirt/water went down the intake.

I get it that "a lot of dirt" went through the intake, but snow and water?
Doubtful water unless you were in it so deep it sucked it through the cold air opening in the grill or between hood and fender area.
And if snow did make it that far, into the air box - it would be harmless.
The only time it would be an issue would be - anyone ever used to watch IRT and up in Alaska during the big blows and snows how they'd have to stop and clear the air filter of snow?

.... Good luck with that warranty claim

Yeah, the dealership/Jeep has something to blame for sure.
Not sure how anyone could even think of blaming Jeep for this one. It's not a defect in workmanship or materials.
It's a replacement parts issue, or an installation issue, or it was run through water - operator error.
This one isn't on Jeep, IMO - but I point back to my other posts - much we don't know and likely never will know or be shown.

there's something missing in all of this.

 

[Rusty PW]

There is an inlet to the air box just behind the grill. Hit the puddle just right. It will soak the air filter.

There was one guy last winter who had snow in his air box. I'm at work, so I don't have time to find the thread.
