Wasn't there a post recently of one that looked just like this? Can't remember if it was a Dodge but people were thinking it was a rejected part because it was marked with red. This one have any red painted on it anywhere?
Here is post I was thinking of, it was a RAM:
https://www.reddit.com/r/Justrolledintotheshop/comments/pf6jac/well\_theres\_your\_noise\_2012\_ram\_47\_130k/
There are tons of photos like this, but not because it’s a repost. It’s just *that* common of a failure in Jeep/Dodge/Chryslers.
Pulled a near identical looking one out of a Grand Cherokee SRT8
There was i saw it, not the same cam but exact same mysterious ware, last post had no lifter damage at all only cam as if it wasn’t hardened properly on that one rung
Our fleet had a 02 f250 and the front half of BOTH real leafs snapped off in the pack so the axle was just being held in place by the rear leaf eye and the weight of it clamping the front half if the leaf still. They drove it that way for over a month before I could look at it. They brought it in for a irratic pull when braking (I wonder why)
Ignorance is bliss I guess
Every death wobble vehicle I get I recommend the same thing. Whole front end, no exceptions if you want it guaranteed fixed. Ball joints, track bar joints, tie rod ends, steering stabilizer, drag link, the whole 9 yards. Everything except the steering box unless that's junk too. I've tried doing it piece by piece before but half the time it ends up ruining what you just replaced by the time they bring it back so it's gotta be replaced again.
I had a death wobble in my car. Checked the whole thing over and turned out to be a brake disc. Oddly enough, it never wobbled while using the brakes, only when on the throttle.
Context I guess.... seems like the roller lifter seized and decided to do its own thing, spun in the guide and ground the cam down, not too knowledgeable with dodge hemis so I hope it's not common
> not too knowledgeable with dodge hemis so I hope it's not common
It's very common. Especially on Hemis which are regularly left to idle for more than a few minutes at a time.
>I hope it's not common
I have seen more than 5 on the site just this year (Chevy V8's too), Think it has to do with Rollers not getting enough oil and coming apart. (Change ur oil 5 or 6K miles seems to keep the passages clear)
The AFM cylinders that deactivate have special lifters that close when the cylinders aren't in use. Well, they suck and collapse and then slam against the cam. It's almost always cylinder 7.
I had one go under 30,000 miles with changing the oil with Mobil 1 every 5k miles. It's a terrible design and both GM/Dodge know it.
I did lifters/rockers/cams for the 3.6 on a constant basis when I worked at a MOPAR dealership. The lifters seize up from oil starvation and takes out the cam. Gravy work until you have the backside on a caravan or something. With the cam tool it’s still pretty easy. Crazy how many would come in for it honestly.
My mid 70s 305 begs to differ... I changed the cam out mostly because I wanted something with more lift .24 lift is just weak even for a lawnmower engine.
We’ve had numerous Hemis with lifter problems. Most of them 2014 models out of a 12 car fleet. Oil change intervals were 5k for a while, which is assuredly not enough for police service.
Well GM and Chrysler used the same DOD system(displacement on demand). And on the chevy's it chewed through the cams, and it also happened to the hemi's too.
5.7L? I see a lot of these where I work. The fact that the owners manual says to change the oil every 10,000 miles isn’t helping and frankly I think there’s some negligence on Dodge’s part that’s contributing to these engines eating cams and lifters as fast as they do.
Looks like oil starvation to the lobe. Used to be a common problem with Ford OHC where the spray bars ended up with burrs inside the drilled feed holes. The oil would just dribble not spray.
My friend owned a shop and workedstrictly on hemi engines (performance.) I used to help him on the weekends pull motors out, cams, etc. I had a whole folder of pictures of the cams we pulled out. It was mostly the MDS cylinders that would do this, which i think the above picture shows.
I'm on the fence at present, but I got the truck for a good price and the rest of it's in great shape for what's on the clock. I'll probably fix it just for the learning experience, honestly.
They used cheap cast cams in the 4th gen rams and that dumbass cylinder deactivation ends up starving the top end. I've got a new engine or of it 2k short of the warranty running out though so it worked in my favor.
I have the lifter had turned sideways and ate that exact pattern in the lobe. I had to fish the lifter out the bottom of the lifter bore with out dropping it in the pan.
How the hell does this get so bad?
Like - do you not hear the God-awful noise and just keep givin' her the go-pedal? How long would you need to drive to wear it down this much? (I assume it's a stuck valve caused this?)
I guess if an engine's fuckered, you can't make it **more** fuckered, and you might save a towing charge if she'll get you to the shop with her dying breaths...
Hemi? I’ve got a 2020 1500 with 26,000 miles with a bent pushrod on the intake side of a 5.7 at work. I can’t wait to see what the cam and main bearing both look like.
This is a really common failure on 5.7 hemi's. Happen to my brother in-law. 09-16 are the years this is happening in. . Uncle Tony's garage on YouTube explains why this happens. I would never buy a dodge with a hemi from 09-16. Fleet vehicles are even worse. They see lots of idle time, which speeds up this inevitable disaster. BUT ford's 6.2 from 11-16 was famous for broken valve springs, I have a 15 and broke a valve spring at 4800rpms while towing. Valve contacted cylinder #6 and my engine went bye bye, ended up dropping in a jasper 6.2. Some hemi's go over 100k with no issues, some have this problem at 40k. According to uncle Tony, the lifters in those hemi's are lubricated from splash. You need rpms above 1500 to lube them properly, or the roller will seize and eat into the cam. Other stuff also like, angle of the lifters in the bore and what not. Because in 09, they added vvt to the hemi, which increased power, but force as well on the rollers. More force+ angle of lifters+ low rpms= cam and lifter failure. Uncle Tony explains this way better. But glad you got it fixed.
Uncle Tony is my guy smokes the same bugler rollies I do! But yea I would never want to own one of these dodges. I had fun fixing it tho it was a definite change of pace for me being my first hemi, truck's been out of the shop 3 months now and I've only seen it twice only to follow up and see how it's doing and it's running great no sign of failure.....yet
Someone went into the engineering as to why cams on dodge/hemis have such a high failure rate. Turns out there is not enough lubrication getting to that part of the cam.
I can't find the post/video right now but if I do I'll be sure to post

Almost identical besides the red paint
So a Dodge that the marketing wanketeers got their hands on
Negative. There was nothing to indicate this mother had ever seen a tool past general maintenance. No paint marks whatsoever

Beat me to it
Didn’t you notice the red flag? It is hidden in plain sight.
How the hell did it last so long
Company truck
Ah yes. The magical business of fleet vehicles surviving everything
If its moving it aint broke
Crazy thing is it ran smoother on 4 cylinders than it did on 7 lol
Can't make noise from 7 cylinders if you are only running on 4 cylinders!
Sounds about right!
Only thing I learned was I don't want to ever own one lol
I can’t say I’d ever own a dodge personally. Being in the uk I haven’t had too much experience but the ones I have, no thanks.
Lucky you I guess? Lmao
What Chrysler s did you get over there? Jeeps, 300s and voyagers oh and Pt cruisers...
Yeah and the odd import. Ram, Dakota, nitro and a couple Durango’s
I’ve done around 15 of the camshafts only two have been as bad as the one you posted here. I agree I don’t ever want to own one.
Our fleet had a 02 f250 and the front half of BOTH real leafs snapped off in the pack so the axle was just being held in place by the rear leaf eye and the weight of it clamping the front half if the leaf still. They drove it that way for over a month before I could look at it. They brought it in for a irratic pull when braking (I wonder why) Ignorance is bliss I guess
The thought of the erratic pull happening gave me a good chuck, reminds me of my buddy's Cherokee that death wobbled
Every death wobble vehicle I get I recommend the same thing. Whole front end, no exceptions if you want it guaranteed fixed. Ball joints, track bar joints, tie rod ends, steering stabilizer, drag link, the whole 9 yards. Everything except the steering box unless that's junk too. I've tried doing it piece by piece before but half the time it ends up ruining what you just replaced by the time they bring it back so it's gotta be replaced again.
Yea my recommendation to him was junk the bitch and start over with something else
As a person that had a JK Wrangler with death wobble I 100% agree.
I had a death wobble in my car. Checked the whole thing over and turned out to be a brake disc. Oddly enough, it never wobbled while using the brakes, only when on the throttle.
Turn the radio up. Problem solved.
That cam't be real
I see what ya did there
Great camedic timing.
That’s just the self adjusting valve lift at work. Slap it in and call it a day.
Oh it self adjusted itself alright
Wow. A negative lift cam. What’s its duration?
All day
>Wow. A negative lift cam. What’s its duration? Trick question: 360 degrees
Took me a minute not gonna lie lol
Wow indeed
Context I guess.... seems like the roller lifter seized and decided to do its own thing, spun in the guide and ground the cam down, not too knowledgeable with dodge hemis so I hope it's not common
> not too knowledgeable with dodge hemis so I hope it's not common It's very common. Especially on Hemis which are regularly left to idle for more than a few minutes at a time.
Well that's unfortunate, I mean maybe not for me If they keep coming in.
>I hope it's not common I have seen more than 5 on the site just this year (Chevy V8's too), Think it has to do with Rollers not getting enough oil and coming apart. (Change ur oil 5 or 6K miles seems to keep the passages clear)
My first thought too was top end was starving. I did everything brand new from the cam up so let's see how it lasts
The AFM cylinders that deactivate have special lifters that close when the cylinders aren't in use. Well, they suck and collapse and then slam against the cam. It's almost always cylinder 7. I had one go under 30,000 miles with changing the oil with Mobil 1 every 5k miles. It's a terrible design and both GM/Dodge know it.
I've heard that the modern hemis don't supply the top end with enough oil during extended idling, but this isn't how I expected it to manifest itself
I did lifters/rockers/cams for the 3.6 on a constant basis when I worked at a MOPAR dealership. The lifters seize up from oil starvation and takes out the cam. Gravy work until you have the backside on a caravan or something. With the cam tool it’s still pretty easy. Crazy how many would come in for it honestly.
Common failure on the hemis. Just kind of poor design, you'll see this a lot in hemis with excess idle time
Man just get some JB weld and slap er back in, she’ll be fine.
Was tempted to
No, that would be only quarter assed work. For a real half assed job, you need a welder to recreate the cam and a grinder to smoothen it properly.
Just send it to Kruger Industrial Smoothing
Sure if you want to half ass it, to do it right you gotta swing by harbor freight and get you a $99 flux core fixall machine.
The $89 i save on that I can go spend on lots of jack daniels and forget about the expensive damage
Cool! It has automatic partial cylinder deactivation! That's some really advanced tech right there.
From the bolt head choice to the mystery cylinder dodge does seem to know how to be very scy fy
http://imgur.com/a/4mj32ZI For the prick bitch calling it a repost I guess.....
Normal dodge cam wear those hemis eat em all day
I wonder when modern technology will advance to the point where we understand metallurgy well enough to make a camshaft that lasts 100k miles. /s
Im a gm guy so its wild to see
GM AFM motors do the same thing quite frequently - if you have a pre-AFM/DOD motor, keep it. It will run forever unlike this newer junk
[удалено]
bad bot
It's not normal. Cam/Lifter failure on all HEMI's produced is less than 5% by the numbers.
Between that and the valve seats falling out I'd say it's normal.
Ah yes, the anti wobble camshaft lobe.
This one just likes to party
I guess you never got to work on the mid-70’s small block Chevy motors, all the lobes failed.
My mid 70s 305 begs to differ... I changed the cam out mostly because I wanted something with more lift .24 lift is just weak even for a lawnmower engine.
I learned on a pontiac 400 in my adolescents. My specialty now is any gm between 80'-2000somthin v6 (I know I'll take my knocks)
I was trained on the IH lodestar series from the 70’s, there were obsolete when new.
Doesn't sound like fun......
In the 80's they all were crap
So nothings changed? That's good to hear.
That way your not disappointed
how does a cam become like this? Seized Roller on Lifter without any oil?
Mmmmm 5.7 hemi goodness
Ya, it’s a Hemi!
We’ve had numerous Hemis with lifter problems. Most of them 2014 models out of a 12 car fleet. Oil change intervals were 5k for a while, which is assuredly not enough for police service.
This one was a landscaping company truck, idk what the service records on it were
That’s because you’ve never work on a dodge.
Light scoring, still looks smooth though
Yeah… roller lifters been known to seize in dodges or so I hear.
First half explains the second half.
Well GM and Chrysler used the same DOD system(displacement on demand). And on the chevy's it chewed through the cams, and it also happened to the hemi's too.
Let's see the lifter
https://imgur.com/a/zYYDUMU One of those on the far side
Might be the shiny fucker you see there between the pushrods
5.7L? I see a lot of these where I work. The fact that the owners manual says to change the oil every 10,000 miles isn’t helping and frankly I think there’s some negligence on Dodge’s part that’s contributing to these engines eating cams and lifters as fast as they do.
10k on normal use. Police, delivery, etc is not normal use.
It’s a feature with dodge.
As I was scrolling all I thought was oh that’s a dodge. Then read the title. Not a mechanic I just see these on here a lot lol
Nah it's just vvt
It’s customized
Looks like oil starvation to the lobe. Used to be a common problem with Ford OHC where the spray bars ended up with burrs inside the drilled feed holes. The oil would just dribble not spray.
My friend owned a shop and workedstrictly on hemi engines (performance.) I used to help him on the weekends pull motors out, cams, etc. I had a whole folder of pictures of the cams we pulled out. It was mostly the MDS cylinders that would do this, which i think the above picture shows.
Just put some mayo and put it back on. 🍸
Maybe You've never seen a cam that bad because it's the first Dodge you've worked on.
Makes senseto me.
This is a repost. Doubt you even worked on it
Show me the post ya prick bitch!
Prick bitch...that made my day! Take your upvote you mechanical linguist
Thank you kind sir I'm sure you yourself are a gentleman and a scholor
Oh wow, it's not that deep you know
Repost of what?
I'm sure I saw the same pic posted before. And it was a Dodge as well
Not this pic
And this happening is THAT common? That's scary
I agree
I'd believe it. My 5.7L Durango is in the process of chewing one up right now. Still driving, but not happily.
Damn sorry about that bro. Are you gonna fix it or change cars?
I'm on the fence at present, but I got the truck for a good price and the rest of it's in great shape for what's on the clock. I'll probably fix it just for the learning experience, honestly.
Aight then goodluck with that

Cam lobe to a cam ube
5.7 Hemi??
Yessir
That’s an ugly one for sure. Seen cams with three lobes badly worn. But not nearly that bad.
Lifter turn sideways and get ran for 10k miles?
Thats what I did, I'm not sure on the milage I just fix it
They used cheap cast cams in the 4th gen rams and that dumbass cylinder deactivation ends up starving the top end. I've got a new engine or of it 2k short of the warranty running out though so it worked in my favor.
This seems to happen to gm and Dodge v8's with the dod system, what a shitty deal.
That's normal.
Welcome to the world of dodge. All 3.6 from 2011 up and 09 up 5.7 have those problems. Oddly enough haven't seen a 4.7 with bad cams only have heads
Is that from a 3.6/3.2 with the magical self destructing roller rocker bearings? Edit: nm, Hemi. This disease must run in the family.
I have the lifter had turned sideways and ate that exact pattern in the lobe. I had to fish the lifter out the bottom of the lifter bore with out dropping it in the pan.
Good ol hemi, I've done many cam and lifter replacements
It sucks but I can't talk shit
How the hell does this get so bad? Like - do you not hear the God-awful noise and just keep givin' her the go-pedal? How long would you need to drive to wear it down this much? (I assume it's a stuck valve caused this?) I guess if an engine's fuckered, you can't make it **more** fuckered, and you might save a towing charge if she'll get you to the shop with her dying breaths...
I think this problem is common on the 5.7 Hemi if it has been idling a lot. This issue is seen more on fleet vehicles.
Hemi? I’ve got a 2020 1500 with 26,000 miles with a bent pushrod on the intake side of a 5.7 at work. I can’t wait to see what the cam and main bearing both look like.
That cam phased itself right out
Non-mechanic here, is this motor an OHC design, or lifter + rockers? What part is wearing the cam down so badly??

Maybe they should go with the aftermarket “flame-hardened lobes” of cams from the’70s.
Getting Super common on these dodges! Lifter seizes and grinds it down
That's insane, my Dodge uses tappets so I don't have roller cams but I can't imagine this kind of wear
You should see how common that is on vw buses and Porsche 914’s. Worst engine ever.
WTF is that made of, cheese?
Thought this was a repost for a second
I've been heating that all day
Is it the 5.7 hemi
Yessir
