Eric O is the man!!
Yep I was just 1600 subscriber roughly found him by accident and now my comments always get lost in a sea of subscribers so I never get a hello from Eric anymore like I used to
I wish Eric was living in my area. I would love him to be my mechanic. He's awesome
Hi Eric! Big fan of the channel. I was the metallurgist assigned to the 5.7L project at Chrysler. Was part of the development team from the beginning. Retired now. I did a lot of the fracture analysis of engine parts during the development phase and from warranty returns. Never saw this failure mode before on a hemi. Usually see valve problems from cam lobe wear due to an incorrectly hardened lobe or a broken valve spring. Valve usually makes quite an impression on the top of the piston. Not seeing that here. I would look for a fatigue crack in the machined ring groove. Part lasted a long time so possible causes might be difficult to isolate. Just fyi. Engine is still junk. Stay safe. Keep truckin'.
Glad to see experts watching and making comments!
Clifford Grupke do you know why so many hemis are having roller bearing issues? I’ve heard poor oil pressure at idle and cheap Chinese bearings🤷♂️
Would long-term detonation weaker the ring lands and/or top of the listing, leading to possible breakage seen here?
Thank you for sharing your professional engineering experience with us!
@@ohboy2592 Been retired since 2008 so I don't know current suppler of roller lifters. I have seen some hemi teardowns on youtube where a roller/lifter was broken and blamed for the engine failure. But if you examine the cam lobe, there is a deep channel worn into it about the width of the roller bearing. None of the other cam lobes on that same cam showed similar wear patterns. If you were to take a hardness reading on the worn lobe, I would expect it to be much softer than either the roller or the other cam lobes. Each lobe has to be heat treated individually to match the roller hardness. Can't remember actual hemi volumes, but for every 100 000 engines, each engine has a cam, each cam has 16 lobes...that means each year, 1.6 million cam lobes have to be hardened correctly. That's about 400 engines per day, assuming 5 days a week, 240 days per year. Its a challenging task that can be a weak point. Valve spring loading is also very high in this engine. Any tiny flaw in the spring wire itself or winding process can result in early fractures. Hope this helps.
points at the guilty party!!!! you did it, lol!
after seeing that, I'm guessing severe overheat and ring seizure, I'd assume it got a load of alcohol, nitromethane, hillbilly NOS spray or big gulp of water in off-road play.
I'm guessing other cylinders are spanked but still firing also. we all know how well liquids compress :)

All potential harbingers of death! Thanks for the video Eric! Let's hope the guy gets another engine. Another 4 part engine replacement video coming up! 👍
But deep down he's like praying its not happening. Just by looking at the engine bay says it all.

Way back in 1978, I was amazed that we had borescope for looking inside the J79 engines on F4 Phantoms. Very expensive tool that is super cheap now and very useful still.
Those battery posts look like the owner takes good care of this one.
Looks like it's one of those "I just drive the damn thing" deals
That's what you get. I'm sure he got good use out of it but could have gotten more.
I wonder if he will keep driving it until it stops.
Biodegradable battery terminals...aka. TTJ....terminal toe jam.😃
That is what that red cover is for. You can’t see how bad it is.
"this couldn't go horribly wrong, so we'll keep the camera running..." - my day is made.
Seen a few Hemi's self destruct. One was due to cylinder deactivation. Driving on the highway for a bit 4cyl mode and then when it jumps back to v8 a surge of heat makes the it drop a valve seat and eats the cylinder and piston.
Eric, my brothers have just finished refurbishing a 2004 Dodge Ram 1500 Quad Cab (looks like the same blue as that one) with the "big" 5.7 Hemi. We are in Texas so my truck has NO RUST. They bought the truck REALLY cheap with a dead engine (thrown piston rod, cracked block). The old block and oil pan had been "repaired" with JB Weld! They rebuilt the engine (donor block, new bearings, rings, lifters, oil pump, bearings). Had the heads done by a local machine shop - new valve guides, valves, planed and Magnafluxed. New radiator, water pump, thermostat, hoses, belts, spark plugs, oil pan, fuel pump. Replaced vacuum lines. Inspected differential and replaced diff fluid. Dropped transmission pan, new filters - pan gasket - and rear trans seal, fresh fluid. U-joints are new from previous owner as were the control arms, all front end parts inspected and tight, all wheel bearings good. New Raybestos rotors and Wagner pads front and rear, flushed brake fluid. New Gabriel shocks all around (original Mopar were still on the truck). New O2 sensors, replaced one catalytic converter with a used one (the blown engine helped kill that cat.) New crank sensor, cam sensor, IAT sensor and MAP sensor (only the knock sensors are old.) Replaced all blower blend doors, blower motor (freezing cold AC!). New ignition switch and drivers door window switches. New Kenwood stereo, Pioneer amp, Kicker speakers and subwoofer. New headlights and tailights. The old Ram sure doesn't look or drive like a 16 year old truck! It was a project truck, it kept my brothers sanity while dealing with the passing of our father last summer - they needed to wrench on something in the shop. I get a cool restored Ram to drive and we kept a Mopar out of the junkyard/recycler for a few more years. Even with all the parts we purchased, with careful shopping the total expense is still lower than a newer truck in worse condition (brother volunteer labor, of course... I had to provide the beer.)
Thanks for inspiring us!
"If WE can do it, you can do it!"
PS: I'll be sending a SASE to SMA to get some stickers, and I'll put one on the Ram!
The second I saw the bent over spark plug, I had flashbacks from when I broke off the top ringland of my Miata. Low speed pre ignition is an evil force.
80/20 rule she still got 87.5% of cylinders working 🤣 it’s a keeper.
Unhook that injector and keep truckin lol
My nebior owns a shop thats what he did. He had a truck go 5 more years on 7. I think he pulled the push rods so the valves stayed closed.
Remove piston debris, re-gap the plug, might still work. It would be good to see if compression still there and whether valves working OK.
@@richardhemingway6084 ... OMG!
@@Wrang15 ... OMG!
I’ve been itching for a video for daysss now. Finally!!!
Came across your channel by accident, liking the videos and the way you diagnose weird and wonderful complaints. keep up the good work.
Hey Eric! Always a good day to see a notice for an SMA video!!
There's your problem lady!
Ball bearings.
One of the best instructional videos you’ve done in a long time
Just a comment to help yours stats. Love the videos. Thank you for all the education you have given me through your videos.
Combination of K&N cold air intake and someone RAMming the gas pedal to the floor. lol
"Can't you just vacuum out the chunks? The top of the ring looks fine."
Glad to see another SMA video. Happy Mothers Day to Mrs O. !
I really enjoy your no-nonsense approach to to engine diagnosis, I wish there was a tech around my area like you.
the valve tried to dodge the piston but the piston rammed right into the valve
Maybe but in my opinion the valve would still be stuck in top of the piston i think the piston ring broke and smashed into pieces. Just my opinion
Good 1
I see what you did there, very punny
This just proves the old saying, "If you can't dodge it, ram it..."
Those are good puns there
Judging by the cold air intake...I'll bet there's a "tuner" on this truck and all it needs is another 200.00 race engine from pick n pull.
Seen that on a hemi before ):
The little camera is a time saver.
Thanks for all the time and editing on videos.
Thanks Ponch, great video as usual.
Those borescope cameras are a great tool to have. I bought one last year for my new-to-me LS3 before a rebuild. But just like you, I had issues getting to see the entire 360º as the rigid ones are a PITA to position properly. Also, they tend to magnify issues - I thought I had massive pitting on the cylinder walls, but once I got the head off I realized they were smooth as can be and it was just staining. But in cases like yours they can save a ton of work and time in diagnosis.
If my battery cables looked like that, my truck would never start. Good luck on the big HEMI!!!
Hi Erick (sorry if that is not your name), I like your videos. You explain the problem and solution in simple way. Keep it like that!
Please also post videos about easy fix things as I am new to car repair.
Stay healthy!
All your videos are interesting and exciting Eric! Thanks!
As soon as I saw the K&N sticker and aftermarket coils I knew this wasn't going to end well.
you're not wrong....tune? too much timing?
Too hot maybe.
Using to much nitrous on stock piston ring gap. Typical pinching causes the piston crown to shatter. Agreed, seeing the K&N sticker plus pinched rings makes me think someone was juicing. 😆
🤣🤣
According to the AERA handbook - that kind of damage is usually caused by detonation or preignition. Teardown and inspection should reveal the cause, but at what cost? The end result is the same "You need an engine". The why is left to us car geeks who just want to know why. Good find and good stopping point!
@Wolf IT Solutions If it were mine and I liked it, I'd rebuild it too. My time for my gain. If I'm fixing someone else's I get paid for my time. Also I thought the new generation of Hemi had aluminum heads and not a true hemispherical combustion chamber. Can't remember the years off the top of my head.
Great camera scope diagnostic! I'm glad you didn't have go that crazy and waste too much time with that. I guarantee that customer don't love that truck enough to do any rebuilds or engine swaps unless it's of sentimental value to him. I know these Hemis are known for broken valve springs that cause low compression but I've never seen something so severe that a piston cracks so bad like that. Awesome video my man!
Thanks for the ride into the Hemi don't get down that way very often! Great job.

Hey Eric
Thank You for sharing your experience and time.
Great Video on 5.7 Ram with broken piston top.
Sincerely Jeff.
Man, I like your honesty.
I enjoy a carnage video when it's someone else's engine!
As soon as I saw the hot air intake and the MSD coils I knew where this was headed.
Eric is the best mechanic. I've thought of shipping my car from Michigan to his shop to have him work on it :-)
Carnage! Thanks for sharing Eric!
Looks like the motor was fed by Stuntman on Neutral Drop.
No way. STUNTMAN only feeds the engines milk fortified with vitamin D. It would never have broken.
WHAT'S IT GOT, STUNTMANNNNNNNN????
No it would be spotless inside from a gallon of fabuloso he put in the oil !

Thanks for showing us, I've never seen a broken piston like that.
From looks of the battery pretty much tells the whole story! Keep up the great work Eric...
Love watching him work. He's very detailed in his videos and I always am able to learn something new from him. He is so very knowledgeable. Also love seeing Mrs O in some of the videos. He is a very honest mechanic and I wish I lived in his neighborhood so I could get my vehicles fixed correctly. Hard to find a good mechanic and an honest one also. Very detailed in all his videos. That makes it enjoyable to watch and less my attention.
You Right Brother
Honesty Today is Rare! Take Care
@@Catayst-123 I'd move into his area, just so I didn't have fix my own junk...
@@stevebates5973 Problem - Rust belt! Is it work halving the life of your car to deal with Eric?
I have a 94 Camry that needs oil leaks fixed. 325,000 miles. It’s a southern car with absolutely zero rust. If the shop was closer I would pull in and keep throwing hundreds at Eric or Mrs O, (is she the accountant?) until he agreed to work on it.
Wish I lived near him. I would give him all of my car repair needs.
Somewhat typical damage resulting from LSPI events (Low Speed Pre-Ignition), possibly triggered by that carbon build-up on the crown of the piston. It could have smacked a stuck valve also, but I'm on the LSPI train from the damage seen.
How would you prevent that?
Hello,
Hope you are doing well. Love the show. Was a certified ASE mechanic in the late 1980's. Went to to school for more of a industrial Electrician, controls etc. I have been doing a lot of Robotics repair for the last 20 years. I'm employed at Honda Manufacturing here in Alabama. We build the Pilot, Passport, Odyssey and Ridgeline. I found you show during the shut down. I love the way you trouble shot this Electrical issues. The way you develop your starting point. This is a skill that some people have issues with. I like all of your Equipment for testing. The test light and a good set of prints is a great tool. I watch another show called Nick's Garage love it. He had a issue with a Voltage Regulator on a 1970 Ford Torino Cobra Jet keeping the primary side of the coil hot with the ignition switch off. I would love to see the prints trying to locate some to trace the circuit. I think that would be a great show, white board the prints and trace it through. Thanks
Thanks for sharing your time and knowledge love your videos

So glad I didn't get the 5.7. I hear so many bad stories. I got the 3.0 CRD and only 1 second difference 0 to 60.
Dodge a Dodge- wise man
They all have their issues, no actual best choice anymore.
Really? How many old Chryslers have you worked on? Don’t confuse the modern Chrysler with the old, pre 1980 Chrysler, very different.
Fun an exciting is the call tot he customer at that point. Guess it's another hemi off the road and off to the big crusher int he sky. Great diag Eric.
I have to agree, the last month and a half has been "Lets replace all the Hemis" where

Interesting that your Autel has no missfire counters for a 2004. I just used my 906BT on a 2001 Dodge 2500 and it had missfire counters under the special functions.

Excellent vid, nice clear look inside that most people don't get to see, some good comments 👍🏽
Great vid, simple diag but still good to show how to use bore scopes and follow through on visual inspection!
The empty NO2 bottle in the front seat was the dead giveaway.
Didn't see a bottle but then again I wasn't paying attention to what's in the cab either.
Cratecruncher
Is that you CNN?
I think you mean N2O, not NO2.... But I did not see the bottle.
missed the bottle also, but I assumed high alcohol, nitromethane or hillbilly NOS kit, followed by severe overheat or drank liquid lol.
Whoosh.
The poor thing finally noticed that Dodge changed its name to Ram--broke its heart and piston.
great video bro keep em coming
As always the best salution . Couldn't agree more
It prob dropped a valve seat. I have worked on quite a few of those 2008 and down Hemi's. The valve seat drops, bangs around and blows a piston out, sends metal throughout the intake and out the exhaust. It is fixable in most cases by pulling both heads, installing a new piston/rod assembly with a cylinder hone, reman head and reassemble everything. You then have to make sure you either replace the intake or shake all the kibbles nd bits out of it.
Not worth it in a 16+ year old POS truck.
the remainder of piston looked too undamaged/flat though, I'd guess ring seizure from severe overheat (alcohol, nitro, hillbilly NOS kit) or it drank some liquid.
then again maybe they just forgot oil check day and it ran out, either way, I'm sure there's other multi-piece pistons :0
Of very specific interest to me since I own this truck.
What did you end up doing with it?.
My o3 2500 just started making an odd noise today at 198k and I'm in jersey but truck is not rusted
A good diagnosis comes from good methodology. Well done.
Nice job there. That Endoscope just paid for itself. Great Luck on it being the first cylinder you took the plug out of. 👍👍
These 5.7 hemis for what Ive seen can be pretty reliable. The 2 guys I know had problem with these is because they NEVER did any maintenance to them.
My cousin had 6 an 08, spun a bearing or 2 lol Decided it was going to end it's life on its way home from work one day
thanks for the tutorial eric👍
Considering it's not a real expensive endoscope it's pretty good resolution. Nice job Eric !
Same reason why my truck is in the shop now. My truck only has 42000 miles on it
It’ll buff right out
Great channel. This guy lives in a different world of mechanics. I can't imagine myself using a tablet to diagnose the problem and Reading codes. With the stuff carbureted I work with I just have to check if I have spark and if I'm getting fuel.
"The money light" LOL! That's the first time I've heard it called that! Ain't that the truth? Love it!
When gen 3 hemi gets too hot the rings like to butt up and blow the crown off the piston like that. They are gapped a little tight. It's a failure mode with power adders... ask me how I know hahaha
I replaced the 203 degree thermostat with a 190 degree thermostat on mine.
So how do you know this? ????

flushed out by un burned fuel.
This needs to be donated to Neutral Drop. As much as Stuntman hates Dodges, he could get it to perform.
I had this similar damage to a 2003 Kia Rio and oddly enough it was 3 days after the first & only time I took it to jiffy lube oh well it had a ton of miles
Wow, hey it was a fun and exciting video, we got to see a destroyed piston :')
I had a simular problem with a 1957 Dodge D100 with a flathead . Driving to work one morning and was in a hard pull and bam. Went on to work, drove it home pulled the head, those old flatheads were pretty easy to work on. The number 3 piston was shattered. Pulled the oil pan, figured i would replace the bad piston, and the rings pulled the number one piston it fell apart when i pulled it out . I replaced 5 pistons (should have replaced all 6) sure enough the number 6, the one i didnt replace the ring land broke hammered like crazy, dead mis. Pulled plug same thing. Replaced the last piston and the old truck ran great for a long time. About 5 years, sold it to a relative, he drove it for about a year gave it to his kid, blew the engine in less than a week. Ran it without oil
Anybody else find themselves tilting their screens screens while watching this trying to get the glare off the AllTell 😊
good old Ringland failure
As soon as I saw the K&N intake..yep she's been hammered on!
...where is that shown in the video?
The endoscopes are a great tool to have. Bought one, but with the flexible line (which doesn't help with control. Added a wire to stiffen it). Helped to save me from pulling apart a blown motor with the same issues. Funny thing is... Looked the same as what you had. Wasn't worth fixing considering it had already had all the valve springs changed 2x.
There’s your problem lady !!!
