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'.
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 :)
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

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.
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!
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.
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.
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.
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.
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.
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. 😆
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.
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!
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
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
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 I work, biggest problem is getting new cam/lifters... Out of stock is the common reply...
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
We have articulating borescopes in aviation but I bought a Teslong borescope on Amazon for home use. It has two cameras, one of them is on the side so you can see the valves. Its still 5mm so it fits everywhere. The resolution is true HD and it has it's own 5" screen. You can save the videos to an SD card and upload it to your computer. I had the same one you're using and for $120, the Teslong one blow it out of the water.
I once had a 351 Cleveland on dedicated LPG that was missing on one cylinder with the same bent over spark plug, replaced the plug and after another hundred or so miles a different plug would go the same and start missing. this happened 3 or 4 times. Time to pull the heads off, I found the valve guides had been working their way down the valve stems and out of the heads, they were getting chipped off by the flare on the head of the valves and the pieces were bouncing around in the combustion chambers closing the gap in the plugs.
LOOKED LIKE MY 97 DODGE NEON I HAD HERE IN CONNECTICUT ONLY 168K ON IT JUNKED IT FOR 200 ALL RUSTED OUT FRAME AND ENGINE DODGE IS KNOWN FOR THAT FORD TOO
Could be LSPI. But this engine wasn’t turbo charged or direct injected. LSPI can blow the ring ridges off a piston, but this form of pre-detonation usually happen on turbo charged or small direct injection gasoline engines. Unless customer was lugging the engine, or it got really HOT, this form of pre-detonation probably didn’t happen. Looks like the metal just fatigued and broke. My buddy Tim the mechanic says that the 5.7 Hemi has several issues with the cam rollers. They stop rolling, and can tear up a cam in short order. Sounds like a metallurgy issue to me. He showed me one and there’s no bearing I could see. Just a pin through the roller. Ugh. Great video!! I love your very methodical and structured troubleshooting!! Thank you!!
wayne skynet Not easy to break someone’s heart! I just a couple of hours ago broke a newbie gardeners heart by telling her her tomatoes are beyond repair! Felt horrible to do so as I have been in that very spot myself.
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
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.
I used to inspect pressure vessels, and we used a boroscope with a joystick. Made it super easy to point the thing exactly where you need it. But it was also thousands of dollars.
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.
The K&N air filter told me everything I needed to know about the cause---young kid driving the snot out of it, holding it to the rev limiter as much as possible
For someone who is constantly bad mouthing the Chrysler mini vans, I don't see too many in your shop. Yes, wiring issues have been a problem, but overall, a good running vehicle. The 4 speed trany is bullet proof & the 3.3/3.8 is the modern equivalent of the 225 slant 6 in terms of reliability. Easy time diagnosis, easy to repair is what I look for in reliable transportation.
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
My Grand Cherokee is an 03/04 (depending on whether you are talking parts or sale year). Not had a great life, but this one makes me sit up and take notice. I'd like to keep "O' Red" for several more years, if I can. I'm glad I saw this one; if something happens to it, I know we can put a new engine into it if need be. Not yet, though. It's a faithful truck.
Does it have a tune to go with the K&N? Early Coyote motors with aftermarket tunes did this. Top ring gets too hot and the ends butt together and the piston top gives way.
You are right, why doesn't matter at this point, it's broken. Another nice thing about the camera, you can show the customer the video, he can see it is broken, too. You're right, replace the engine or junk the truck. Buying a remanufactured engine for a 16 yr old truck does not seem to make sense. It should be easy enough to find one pulled from a wreck and just swap it out.
Man i just got a dodge ram with the hemi 5.7. I hear good and bad things about the hemi motors. I hope nothing like this happens to mine. Love your channel keep making these videos. Thanks big E
If this were my truck, I'd have Eric O driving to the local Pick n Pull and get me the lowest mile engine they had in the yard and pay for the install. From the limited view of the truck, it didn't look crusty, so a bone yard engine would be good enough until the God of NY Salt came calling.
@Sapo 4774 I'm guessing the typical Hemi Valve seat failure. My Hemi Charger did the same thing @ 130k - But mine tore the piston into pieces and put it into the oil-pan
@@RyanHull76 That's what took out the local Dodge cop cars. They bought two, first one failed in ~8 months, second one made it a bit over a year, then they bought Fords. I gotta wonder how much cheaping out on those valve seats has cost Chrysler over the years, it really hurt the reputation of the Hemi in the fleet vehicle market. It's a damned shame too, the rest of the engine is pretty damned solid.
The block is bullet proof! But the Mopar engineers just aren't up to the task yet. They build cars that last 4-5 years, which is what their lending is. Kinds simple to connect the dots there.
well, the Hemi hemorrhaged metal. Easy, used engine, reman or new, customers call, but: since it's a Chrysler, the cost of repairs exceeds the value...
Hemi, Chryslers name for powerless and gas guzzling. We have a 2500 at work, cannot pull 7000 pound trailer to save its life. Accelerator to the floor will not pull going up slight grade.
The one I saw this happen with was from an owner changed his own spark plugs. One did not want to break loose, so he removed it with his impact wrench and the plug end broke off and dropped in to the cylinder. He just left the piece in the cylinder figuring it would "burn off," and put new plugs in it. Amazing thing it was a plow truck, and the engine ran for a few weeks before the damage was evident.
My brother-in-law's Charger had the same issue. 5.7 liter, granulated piston!! Fiat Chrysler is paying for the repairs if your customer is the original owner. Good job!!!
The Hemi sure ain't what it used to be. I used to work with a ton of old cast iron ones. I was never a Mopar fan until I saw what they really were. Now it's just a sales tactic.

the valve tried to dodge the piston but the piston rammed right into the valve

Really? How many old Chryslers have you worked on? Don’t confuse the modern Chrysler with the old, pre 1980 Chrysler, very different.
Seen that on a hemi before ):
The little camera is a time saver.
Thanks for all the time and editing on videos.
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
I work, biggest problem is getting new cam/lifters... Out of stock is the common
reply...
Eric is the best mechanic. I've thought of shipping my car from Michigan to his shop to have him work on 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? ????
@@michaelmartinez5217 ...a little birdie told him(?)
@@daleburrell6273 didn't mean that how it reads. Meant it more towards he's experience with the engine.
We have articulating borescopes in aviation but I bought a Teslong borescope on Amazon for home use. It has two cameras, one of them is on the side so you can see the valves. Its still 5mm so it fits everywhere. The resolution is true HD and it has it's own 5" screen. You can save the videos to an SD card and upload it to your computer. I had the same one you're using and for $120, the Teslong one blow it out of the water.
Hey Eric! Always a good day to see a notice for an SMA video!!
Detonation, cam out of phase or timing issue. Those engines fail quite often. You are right, pull and replace.
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
I once had a 351 Cleveland on dedicated LPG that was missing on one cylinder with the same bent over spark plug, replaced the plug and after another hundred or so miles a different plug would go the same and start missing. this happened 3 or 4 times. Time to pull
the heads off, I found the valve guides had been working their way down the valve stems and out of the heads, they were getting chipped off by the flare on the head of the valves and the pieces were bouncing around in the combustion chambers closing the gap in the plugs.
Same reason why my truck is in the shop now. My truck only has 42000 miles on it
This one didn't hurt too much. Had a 98 same with the 5.7 and only went through 3 transmissions LOL True story. Great Vid !!
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
“You can see what I see and we’ll all see what we see.” This guy cracks me up in every video.
After working on cars for 10 hours a day, I sit down to zone out to tiktok, then a SMA notification pops up.
Me: tiktok can wait. SMA is life!
Foodskewed919 same. I paint cars so this is a welcome change
LOOKED LIKE MY 97 DODGE NEON I HAD HERE IN CONNECTICUT
ONLY 168K ON IT JUNKED IT FOR 200
ALL RUSTED OUT FRAME AND ENGINE
DODGE IS KNOWN FOR THAT
FORD TOO
"Back to reality, oop there goes gravity"
@@ekop1778 it's 23 years old, and its from Connecticut. Im surprised it lasted half that.
Are you 10 years old? why would you go on tiktok 🤢
Could be LSPI. But this engine wasn’t turbo charged or direct injected. LSPI can blow the ring ridges off a piston, but this form of pre-detonation usually happen on turbo charged or small direct injection gasoline engines. Unless customer was lugging the engine, or it got really HOT, this form of pre-detonation probably didn’t happen.
Looks like the metal just fatigued and broke. My buddy Tim the mechanic says that the 5.7 Hemi has several issues with the cam rollers. They stop rolling, and can tear up a cam in short order. Sounds like a metallurgy issue to me. He showed me one and there’s no bearing I could see. Just a pin through the roller. Ugh.
Great video!! I love your very methodical and structured troubleshooting!! Thank you!!
Aww thats a painful site. Break the news to him easy Eric
wayne skynet Not easy to break someone’s heart! I just a couple of hours ago broke a newbie gardeners heart by telling her her tomatoes are beyond repair! Felt horrible to do so as I have been in that very spot myself.
Sight... (roll eyes)
@@bjbeardse ... Agree.
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
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.
Wes-When do you sleep ??????
Mine doesn't Wes and same truck same scan tool
Glad to see another SMA video. Happy Mothers Day to Mrs O. !
"Can't you just vacuum out the chunks? The top of the ring looks fine."
Considering it's not a real expensive endoscope it's pretty good resolution. Nice job Eric !
I enjoy a carnage video when it's someone else's engine!
I used to inspect pressure vessels, and we used a boroscope with a joystick. Made it super easy to point the thing exactly where you need it. But it was also thousands of dollars.
The poor thing finally noticed that Dodge changed its name to Ram--broke its heart and piston.
Came across your channel by accident, liking the videos and the way you diagnose weird and wonderful complaints. keep up the good work.
Combination of K&N cold air intake and someone RAMming the gas pedal to the floor. lol
Great vid, simple diag but still good to show how to use bore scopes and follow through on visual inspection!
Looks like the Neutral Drop boys put some of their “special additives” in that engine!
that's just from typical dodge trans. function
The spark plug told the piston debris to "GET OVA HEEEA"😁😎
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.
Hey Eric
Thank You for sharing your experience and time.
Great Video on 5.7 Ram with broken piston top.
Sincerely Jeff.
The sadist in me want's you to record the phone call when you break the news to the owner!
One of the best instructional videos you’ve done in a long time
I guess the piston... uhm... RAMMED itself into the valve and broke it..
Wow I got that
Spark plug didn't dodge the shrapnel.
That joke is Le Barren of humor.
Rim shots galore!
...awright piston- YOU'RE BUSTED!!!
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.
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 K&N air filter told me everything I needed to know about the cause---young kid driving the snot out of it, holding it to the rev limiter as much as possible
Wow, the barf-o-cam was really moving today!
For someone who is constantly bad mouthing the Chrysler mini vans, I don't see too many in your shop. Yes, wiring issues have been a problem, but overall, a good running vehicle. The 4 speed trany is bullet proof & the 3.3/3.8 is the modern equivalent of the 225 slant 6 in terms of reliability. Easy time diagnosis, easy to repair is what I look for in reliable transportation.
CHRYSLER - Company Has Recommended You Start Learning Engine Repair
Nice acronym 😁
That's a long acronym!
after the merger you need to Figure In A Transmission too
spotless304 Might as well Just Empty Every Pocket..
Awesome !!!
We believe you Mr. O! Once you see that different shade of grey you know whats broke. Thank you for the vid!
It’ll buff right out
Lucky you pulled the right sparkplug the first time. I bet it's on the way to the pick and pull.
So what your saying is get a magnet grab the pieces out and stretch the plug out. Then either drive it or sell it.
Aluminum isn’t magnetic!
Thank you Eric ❤ got a 2007 5.7 litre hemi in a 1947 International pick up with issues…ticking noise and maybe misfiring 😢
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
My Grand Cherokee is an 03/04 (depending on whether you are talking parts or sale year). Not had a great life, but this one makes me sit up and take notice. I'd like to keep "O' Red" for several more years, if I can. I'm glad I saw this one; if something happens to it, I know we can put a new engine into it if need be. Not yet, though. It's a faithful truck.
Does it have a tune to go with the K&N? Early Coyote motors with aftermarket tunes did this. Top ring gets too hot and the ends butt together and the piston top gives way.
interesting theory watson
It wouldn't surprise me if that was the situation, or if someone just used a cheap tuning device.
How bout a tuner with the owner running low octane fuel when program reccomends 91 or higher..major detonation..seen it happen
You are right, why doesn't matter at this point, it's broken. Another nice thing about the camera, you can show the customer the video, he can see it is broken, too. You're right, replace the engine or junk the truck. Buying a remanufactured engine for a 16 yr old truck does not seem to make sense. It should be easy enough to find one pulled from a wreck and just swap it out.
I asked Scotty and he said, while spitting, "Toyota! Toyota! Toyota!"
Thank you Dr Eric O. Do you own a top side creeper? Ever try one? Have a blessed and safe week to you and your family.
I’m curious if the ring gap closed and the ends touched.
Man i just got a dodge ram with the hemi 5.7. I hear good and bad things about the hemi motors. I hope nothing like this happens to mine. Love your channel keep making these videos. Thanks big E
Geez, looks like the piston was chunked. i can see one of the piston rings, the top land is broken off.
Thanks Ponch, great video as usual.
There’s your problem lady !!!
Man, I like your honesty.
Anybody else find themselves tilting their screens screens while watching this trying to get the glare off the AllTell 😊
Nice job there. That Endoscope just paid for itself. Great Luck on it being the first cylinder you took the plug out of. 👍👍
If this were my truck, I'd have Eric O driving to the local Pick n Pull and get me the lowest mile engine they had in the yard and pay for the install.
From the limited view of the truck, it didn't look crusty, so a bone yard engine would be good enough until the God of NY Salt came calling.
If that were my truck I would have him leave it there!!
I dunno... i would’ve cleaned the cylinder and then put it back together.
@Sapo 4774 I'm guessing the typical Hemi Valve seat failure. My Hemi Charger did the same thing @ 130k - But mine tore the piston into pieces and put it into the oil-pan
@@RyanHull76 That's what took out the local Dodge cop cars. They bought two, first one failed in ~8 months, second one made it a bit over a year, then they bought Fords.
I gotta wonder how much cheaping out on those valve seats has cost Chrysler over the years, it really hurt the reputation of the Hemi in the fleet vehicle market. It's a damned shame too, the rest of the engine is pretty damned solid.
The block is bullet proof! But the Mopar engineers just aren't up to the task yet. They build cars that last 4-5 years, which is what their lending is. Kinds simple to connect the dots there.
A good diagnosis comes from good methodology. Well done.
I wanted to see it running with the old spark plug regaped.
Ha , no doubt the old crumb will run for another couple years like that.......
@Eric Wood NY state inspection, truck would never pass.
my apologies if I cannot detect sarcasm.
Just a comment to help yours stats. Love the videos. Thank you for all the education you have given me through your videos.
I’ll bet it was dead or nearly dead from salt before the piston broke.
As always the best salution . Couldn't agree more
well, the Hemi hemorrhaged metal. Easy, used engine, reman or new, customers call, but:
since it's a Chrysler, the cost of repairs exceeds the value...
LIKE MY 97 DODGE NEON 4 DOOR
JUNKED IT FOR 200 ONLY HAD 168K
Hemi, Chryslers name for powerless and gas guzzling. We have a 2500 at work, cannot pull 7000 pound trailer to save its life. Accelerator to the floor will not pull going up slight grade.
@@ekop1778 what do you mean "only" ? It's like a miracle you got 168k out of it.
@@ddorn04 probably plugged up the CATS within the first 5K miles lol
Id like to see the plug electrode trimmed off for a side gap and screw it back in . Light her up and see how far it gets!.
The one I saw this happen with was from an owner changed his own spark plugs. One did not want to break loose, so he removed it with his impact wrench and the plug end broke off and dropped in to the cylinder. He just left the piece in the cylinder figuring it would "burn off," and put new plugs in it. Amazing thing it was a plow truck, and the engine ran for a few weeks before the damage was evident.
Rebuild vs. replacement engine cost. Cheaper to replace, possibly?
If someone's paying for it - replace. For a do yourselfer who knows what he's doing - repair.
My brother-in-law's Charger had the same issue. 5.7 liter, granulated piston!! Fiat Chrysler is paying for the repairs if your customer is the original owner. Good job!!!
The Hemi sure ain't what it used to be. I used to work with a ton of old cast iron ones. I was never a Mopar fan until I saw what they really were.
Now it's just a sales tactic.
