Yes, an excellent video. I like the diagnosis of strange problems the best. I still like all the other videos. You can only fix what comes into the shop.
For me, diagnostic videos where one or more other shops have failed to find the problem are the most interesting. It’s solving a puzzle. Routine parts replacement videos are the ones I skip!
I like these diagnostic vids for the educational value, but I also like the parts replacement vids because Eric usually in a goofy mood and it is pure entertainment, especially when Mrs. O is around. Those 2 are hilarious.
I love these diagnostic docudramas!

God bless a man willing to share his knowledge so expansively without any agenda other than to educate. Many thanks Eric O!
Boring? No. That was brilliant! Love that we saw the issue digitally and then physically. This one was, obviously, way over the head of those first two shops. Great video
I agree. I am an engineer and just fascinated with the complexity of cars today. How do the great shops and techs capitalize on their knowledge? Sometimes Eric will find a bad wire where other shops have thrown $1000s in parts at a problem. How do great techs get paid their value? They save customers time and money.
That’s because the first two shops are like many of them out there they suck! they’re not real mechanics they’re part replacers any real mechanic with real skills can find stuff at this level !there are a good amount of them out there like Eric but the ignorant ones far out number the good ones
Dying breed? I think rare breed. How old do you think he is? He's at the good age where he has a good amount of experience to know what to look for and how to diagnose. If you get older guys, they're going to be like, "I don't know how to use a laptop. Back in my day, it could have only been 3 things. We didn't need all these sensors." You want a well-rounded 30-45 year old working on your stuff. Not saying everyone in that age range will fit the bill because there are some people out there who just don't care, but that's where you'll have your best chance of getting someone good. But there will be more. The next generation will keep pushing forward and learning. These guys aren't going anywhere. They've always been a rare breed. It takes talent, skill, will, and integrity to be good at your craft. But more will come, and they are out there. Just gotta find them.
Its because there is no money in it. The amount of tools you would need to do this type of stuff, diagnosis and reprogramming, is actually insane. Thats if the manufacturer will sell you the tools to work on the stuff to begin with. You will see on youtube the only people doing it are people who own their own businesses and can fully extract every dollar of profit from the work they put in. Thats literally the only way its fiscally feasable anymore.
Eric, I've been in the heavy equipment/truck repair business for 45 + years and have worked with or managed dozens of various skill level mechanics and have never seen any with you patience and troubleshooting skills , your ability to logically build a case without pre determination of a cause and to gather evidence without destroying it, is what puts you where you are, yes the tools at your disposal helps but at the end of the day it is your brain power that gets the job done.

As a past mechanic, electrical is the hardest thing to diagnose. You make it look so easy. A person can say the other two shops should have found this, but it's not that easy. You need the tools, understanding, skills and above all the patience. You have it all. Excellent work.
@@milesmahan It's a mechanical problem that would have been next to impossible to find had it not been approached as an electrical problem. To accurately diagnose modern vehicles you need a complete understanding of both and how they interact.
Oh I can appreciate that its difficult to find these kind of problems, but the annoying part is that all these other shops keeps throwing in replacement parts because they try to be helpful? Id rather they admit that they cannot find the problem without starting to make me pay for parts I don't need.
Never boring at all. What a pleasure to see a true professional mechanic at work. What I mean is, a trouble shooter, NOT a parts changer! Thank you for your channel. For your effort & time to produce these clips.
I thoroughly enjoy watching a real diagnostic process. I'm so tired of folks throwing the parts cannon at things because the code says a part lost communication. I want to know why? Bad ground, broken tone ring? Loose wire? What is it? Eric will find it
As a DIYer (with some shop experience) it's awesome to see videos like these, I love the problem solving aspect and I don't get to see oddball problems like these, but Eric takes us on the diagnostic journey with him!
Way to go, pro. Your understanding of mechanics is second to none! Your ability to explain problems to us is incredible too. I wish I lived in your area.
Eric, I don’t believe any other tech on the planet would diagnose this so in depth. Your showing the picture of the part then watching it move in the engine and seeing the problem happen as you rotate the engine… so cool! And I’m 75 years old so I’m super impressed
Me to but this is impressing at any age. The young guns need to get into this Tech me I'm 59 and don't like dealing with all this new stuff . I like saying they don't make them like they use to !
This is easily my favorite diagnostic ever. You had an electronic issue with a mechanical cause, and no codes or sounds or smells to point you in the right direction! Fantastic job!
What sets Eric O apart from other automotive channels is his understanding of the diagnostic tools he uses, but also his knowledge of how an engine and electrical system function in congruence. This is not only world class repair, but something most mechanics are not willing to put in the effort.
I've worked, in automotive shops for 20 years. I've seen good mechanics, great mechanics, Mr. O you are by far the best I've ever seen. I've known mechanics that pass the ASE exams with flying colors, but they still have problems just doing a coolant flush.
That was not boring at all. I love your excitement when you discovered the banging on the sensor and the improvised "stethoscope" to let us hear it. Your ability to take complex data and simplify it to reach a diagnosis is impressive.
I have to put this out there - SMA is the best auto mechanic channel on YT by so much, it's crazy that some other guys have more subscribers. Must be that those guys still have subscribers from years and years ago, when they had the field to themselves. Eric O has got to be the hardest working man in the "working and making a video at the same time" business. This is another good one.
It amazes me how many shops with "mechanics" don't do the basics of diagnostics and simply throw parts at it. Especially a lot of them on RUclips, great video as always Mr O!
Not even so much that, I'd completely accept a garage not being able to diag this fault. In reality your likely not finding that without a scope. The issue is who's paying for all the guess work, yes it might be an educated guess, but the problem is how much has the customer shelled out for work that wasn't necessary. The industry would be much better if garages were honest and said we don't know.
The problem is, the shop only pays the mechanic 1 hr and that’s all the time they get to diagnose a car and then pressed to give a best guess. That’s sufficient only for about 70% of the jobs. Other diags like this one need to pay more time but shops fear asking for more time and the mechanics get screwed over.
@@renewedautodiagnosticsllc1789 doesn't really apply here in the UK. People are on hourly in terms of if they have a bonus system their hours are tracked, but no garages pay mechanics based on hours booked out. You earn a basic salary for doing your job
Fantastic diagnostics on this one. You combined visual inspection, electronic inspection, tactile inspection, and testing your hypothesis and followed the evidence to exactly where it led instead of guessing or giving up because it was a pain in the butt. This is a true lesson in how diagnostics are supposed to be done. Very well done!
Super impressed with your diagnostic skills Eric. This was not at all boring, held my interest all the way. Your ability to actually show us what's happening is a huge plus. Thank you.
Your episodes are of Great Value to anyone who is/was in the trade. We have all run into that problem vehicle that has us banging our head against the wall. The art of diagnosing and explaining the steps is a Great asset to you and your shop.
These episodes are my favorite. Thanks for keeping us entertained, Eric. We may even learn something from time to time. I don't understand how that is not a sensor correlation or performance error. The PCM should know and keep track of the length of the pulses and their edges. They just aren't even looking for that probably, or it doesn't fit some idea of what a failed sensor or sensor error looks like. A loose reluctor wheel should be a failure that make it into the DFMEA.
Great job troubleshooting Eric! As a former electronic technician on some of the world’s most advanced airborne radar systems, NOTHING was more rewarding than finding the “root cause” of an intermittent failures that others simply wrote CND! Kudos!
Honestly Eric your one in a million. You have an inherent interest in root cause analysis. This to me is your TOP #1 VIDEO OF ALL TIME. What's kind if sad is it took passes by 2 previous shops and tons of $$$$ before a true problem solver diagnosed it. Like I always say, when I need surgery I'm having my doctor call you in for assistance. Your the best man!!!
There has never been a better diagnostic video done. It very much proves that true diagnostic gets to the actual source and doesn’t melt the barrel of the parts cannon. From one tech to another,amazing job and analysis. Breaking it down for the viewers was spot on. 👍🏻
Eric that was the most entertaining show of not giving up, finding the problems that other shops cant. I just want to say you are one of the best mechanic that I watch on you tube. Keep the videos coming!!!!
I have to say, your diagnostic skills are amongst the elite in this industry. It's always a pleasure to watch your videos. If all mechanics were like you then there would be not junk yards, except when they rust apart...A+ video!!
This was Awesome! Actually showing the timing wheel and how it relates to the two big and two little spikes on the scope, then following it up with the bore scope inside the sensor hole was awesome! On so many other diagnostic videos I don't understand what the sensor is telling us. So cool to have a confirmed diagnosis too, your work and your videos are top tier.
Excellent job! As a fellow mechanic, your videos are always intriguing. From diags to brake jobs, you’re the standard! I send your videos to young techs getting started. The small details you include, that take years to figure out is invaluable to this industry. Much love Erik, many blessing to you and your family ❤
You outdone yourself with visual aids on this video Eric! The excitement in your voice when you saw the vane phaser move out then in was gold! Seeing the smoking gun, especially an unexpected one clearly brings you some joy. It is a good feeling when your day brings you something new - even when you have been around in your job for a while. Great work Eric 👍.
Eric. I love the fact that you are so humble. You are a brilliant diagnostic technician. It was great to see the digital problem and the physical damage that was causing it. This is one of your best vids. Far from boring.
You did it again. You elevated yourself far above the rest of the crowd. The real value is not so much your tools, it’s you and your experience. Very impressive.
Superb thought process and diagnostic, Eric! That timing disk is completely loose. No parts cannon would solve this - only a scope could give you insight on what was going on. Well done!
Top notch! As a home remodel/repair contractor, I never would have found this, but I'm thankful folks like you exist who are willing (and able) to track down the root causes. I try to do the same in my field, instead of smearing lipstick on the pig's behind and letting another sucker kiss it, and you're an inspiration to that. Thank you!
You are so much more animated and involved when the problem is complex. Electrical issues are so much harder and challenging than something like brake repair which you were bored with a couple of weeks back. Thanks for taking us through your thought process. Great instruction in moving the problem way down the road! Thanks again for another great video!
Yeah, he even said "Lemme just check this one thing before I go home for the night..." and then he's taking the tire off, running a borescope, and turning over the engine. He was about to go home but he knew he was close to figuring it out and he was just as excited as we were to get the answer.
EXCELLENT video. The old saying is true, "Third shop is a charm!" This is proof that AI will never replace technicians. I always love a video that starts with "no codes". Those are the best.
The same goes for pilotless planes or cars for that matter. Take a driverless car on a windy mountain road with adequate line markings and you will end up crashed because AI can't keep up. The important part of landing a plane is dealing with wind variations and a computer cannot react like a person can. In reality this car would be destined for the scraper if it can't be fixed. The eventual way repair work is headed. (throwaway society)
@@larrybe2900 Everything gets thrown away eventually. I got called very dark when I was sitting in a room and said everything in this place will be disposed of in a small period of time (including the people). The car is 12-13 years old. It lived a useful life. Is somebody going to put timing chains on it for 3-4k? Maybe, maybe not.
As someone who loves nitty gritty, how-it-works, behind the scenes parts of life, I love the case study videos. I also love the videos where the Dawg has to come out and just abuse some rusted junk down to generic brake jobs. I learn something every time. Keep it up, SMA!
Th3 only thing I can say is “wow”, what a skill ! There are over 50 thousands parts to build a car, you, right away point to the right direction, absolutely amazing.
It's interesting to watch both you and Ivan when you are doing diagnostics and see not only the process, but hear the thought behind it in a manner that is super easy to follow and understand. Even more so when you show us the problem as it's happening - which isn't always easy to do, but it explains it far better than anything else.
This channel has some of the best procedurals. I swear you could make a series of diagnostics like this and sell it to the networks as a reboot of House MD.
A workmate had a similar issue with his brand new SAAB. It would die randomly sometimes restart others not. After having been towed to a bunch of shops over half the country it was bought back to be thoroughly examined. They found the cause, a loose or missing nut on a ground lug under the rear seat (multiple wires)!
Love the channel even though I'm not all that interested in vehicles. I'm IT and electronics so I greatly enjoy the troubleshooting videos like this one. Your knowledge of the electronics, sensors and communication systems in a vehicle and how to use meters, scopes and other measurement tools to troubleshoot along with a systematic, logical approach to isolating faults sets you apart from most mechanics. You are among the best in the business and on this platform. You're a great teacher.
You make it sound logical and even easy. I can follow your thinking but the knowledge of how all the digital electronicals work is irreplaceable. You are NEVER boring to learn from. Thank you Eric.
That video was the farthest thing from boring! Extremely interesting diagnosis from a goofy waveform, to an obvious rapping sound, and finally the visual confirmation of what was happening. Kudos Eric and yet another reason why you have such a loyal following on RUclips.
This was amazing! It's not surprising to see other shops that couldn't diagnose it, but it's incredibly sad to see some of the cannon parts that were thrown at it.
I cant say I never threw parts at a car to try to fix something but I'm atleast in the ball park, spark plugs and ign coils for a car that's stalling 🤔,
Brilliant, truly excellent the way you found this fault, great video as usual, I have been a mechanic for 35 years and I am still learning stuff everyday. All the best from the UK Thanks Eric 👍
Wow - how is an engine with only 100k miles on it needing such a massive repair already? Great work Eric on finding the cause and using some deductive reasoning. Even though I'm not a tech, I enjoy watching you solve these strange problems
Really hope this woman didn't pay for the other work that was done. If she did, I'd be fighting to get my money back. Nothing against the mechanics, they tried even if by just guessing. Good job and thanks for showing and educating. It's good to learn these things.
Brilliant work Eric. In my work as as a HW (electronics) design engineer I'm often tasked with debug and root-cause analysis of hardware and firmware and it's often the most enjoyable part of my job: Catching your "prey" after a good "hunt" is most satisfying. Your systematic, logical approach, taking a step back and seeing a ten-thousand-foot view of a problem to really root-cause it is so refreshing in an industry where the parts cannon generally seems to be the weapon of choice.
@0:17 - "it's gonna be kinda boring"????? I say "Nay, nay!" Best video you've ever made! This level of diagnosis is superlative. No parts canon required.
As a retired engineer, I agree. Eric comes about the closest to using good engineering troubleshooting skills as any mechanic I have ever known. And he is very competent in many skills, mechanical, electrical, electronic, welding, etc. He reminds me somewhat of Dave Engel at Engel’s Coach Shop in Joliet, MT. They work on completely different things, but Dave is similarly versatile and logical in his approach.
As a former Electronics Technician and a currently semi-retired Electrical Engineer (as well as a shadetree automotive tinkerer), I found this video to be extremely entertaining and informative. I still get that giddy feeling when I zero in on a fault in piece of equipment, and when you saw that cam phasor reluctor flopping around on the borescope, I had an inkling that you felt the same feeling. I thoroughly enjoy your videos, and I wish I lived closer to you (I live south of Pittsburgh) so I could glean some of your wisdom. I would definitely bring my vehicles to you! Keep 'em coming, Eric!
Eric, this is a pretty new video and yet here I am watching it again! I'm not a mechanic, I'm just a guy that loves when someone like you finds the problem when two other shops just loaded up the parts cannon. Keep em coming Eric, you are the man!!
What truly separates a great all round mechanic and a parts cannon mechanic ...Eric O takes his skill and knowledge to another level to diagnose a problem ...brill diagnostic video ....as for tracing the problem i would send it to Eric O first 😅😂
As a retired electronic technician, I find this kind of video to be my favorite. I have always found the hunt to be far more enjoyable than the actual fix. ESPECIALLY, when others before me have tried and failed. Fascinating video! How do you keep from being swamped with overwork?
This video is so good that when I accidentally started rewatching it, I didn't move on to something else. This is perfect example of "real world" crap that goes wrong and can ruin a household if there weren't good shops & techs
Now this is a real mechanic at work. I can’t believe 2 shops are just throwing parts at it, without knowing what’s really causing the problem. You just showed us (again) the difference between a mechanic and a “parts changer” as we call it in my part of the world! The scope and camera are essential to do this fine job! Keep up the good work! Greeting from the other side of the pond….😁
@@mph5896 I’m aware of the complexity in this problem and diagnostics in general, but that’s not an excuse to not dig deeper instead of throwing parts at it. Most mechanics are not really interested in their job and try to solve problems the easy way by guessing….
Many shops allow their skill at "assuming what is causing a problem" rather than allowing their thinking pattern to start with the basics gets in the way. I realize that "shooting parts at it" takes less time and effort, but if you didn't fix the problem, what good were your efforts...other than making "parts markup" money for your shop? I'm 80 years old and long since retired. In an electronic engine repair, I'd be lucky to find my butt with two hands searching, that's why I leave the repairs to good shops with repair people who are qualified to work on them. I was a fire vehicle mechanic but retired when technology passed me by.
@@georgewhiteman7341 20 years ago the fire department I was doing paramedic clinical with had a new engine that would shut down every time they went to pump with it. It was equipped with all the new electrical technology instead of the old manual pto. They had it in for repair multiple times but it was intermittent so😅. Nothing like a limp hose when you have a roaring house fire🙃
The way you took us from the beginning to the final discovery of the problem is perfect. I am a mechanic and the whole time I was armchair troubleshooting right along with you. Awesome video!
Wow...that was really something. How could the right tire needing air break that cam trigger.....LOL! Great job finding the problem. Total respect for you an your abilities to not just throw parts at a problem. You always take the time to find the problem, then fix it. Big pat on the back Mr O.
This is diagnostic work that probably 95%of techs out there arent able to do. I found a local guy who is honest and good but Eric is next level and there just aren't but a handful of techs like him in this industry. Very awesome video. I love this!
One of your best videos when it comes to diagnostics. You traced the problem, proved it electronically, then double proved it mechanically. Excellent work once again.

Yep, he's a stud at diag! Even with a pile of crap like that, the 3.6 was supposed to replace the 3.8 series 2, one of the best GM engines ever
Ditto that !
It's an excellent example of diagnostic prowess. It's how EVERY shop should do it, unless they specialize in old iron, LOL.
For sure!
I always learn something new, that megaphone was genius

@@milesmahan It's a mechanical problem that would have been next to impossible to find had it not been approached as an electrical problem. To accurately diagnose modern vehicles you need a complete understanding of both and how they interact.
Agreed~!
Oh I can appreciate that its difficult to find these kind of problems, but the annoying part is that all these other shops keeps throwing in replacement parts because they try to be helpful?
Id rather they admit that they cannot find the problem without starting to make me pay for parts I don't need.
Never boring at all. What a pleasure to see a true professional mechanic at work. What I mean is, a trouble shooter, NOT a parts changer! Thank you for your channel. For your effort & time to produce these clips.
What an jncredidble mix of high tech diagnostics and old school mechanics, Picos and screwdriver stethoscopes!👏👏😅
@@LouisPrive The stethoscope was great.
I thoroughly enjoy watching a real diagnostic process. I'm so tired of folks throwing the parts cannon at things because the code says a part lost communication. I want to know why? Bad ground, broken tone ring? Loose wire? What is it? Eric will find it
This is an instant classic. I enjoy all of your videos, but diagnosing strange problems and then explaining them to us is where you really shine.
I couldn't agree more, Hey folks if you want to see Rust move on LOL! Nope, this was one of the more interesting videos!
Great job Eric it’s a pity the techs in the other two shops aren’t as smart as you then the customer could have saved themselves money. 😃
As a DIYer (with some shop experience) it's awesome to see videos like these, I love the problem solving aspect and I don't get to see oddball problems like these, but Eric takes us on the diagnostic journey with him!
@@tomjohntig No codes and the other shops were lost.
Way to go, pro. Your understanding of mechanics is second to none! Your ability to explain problems to us is incredible too. I wish I lived in your area.
Eric, I don’t believe any other tech on the planet would diagnose this so in depth. Your showing the picture of the part then watching it move in the engine and seeing the problem happen as you rotate the engine… so cool! And I’m 75 years old so I’m super impressed
So, you're saying old people are easily impressed...
Me to but this is impressing at any age. The young guns need to get into this Tech me I'm 59 and don't like dealing with all this new stuff . I like saying they don't make them like they use to !
I could hear a strange tick on the video. Any mechanic with good hearing should have found this.
This is easily my favorite diagnostic ever. You had an electronic issue with a mechanical cause, and no codes or sounds or smells to point you in the right direction! Fantastic job!
No sounds? He had an Edison player with a cam sensor for a stylus!🤣I hope he gets the job because he deserves to.
@@InsideOfMyOwnMind Great point! The windshield washer bottle Victrola!
What sets Eric O apart from other automotive channels is his understanding of the diagnostic tools he uses, but also his knowledge of how an engine and electrical system function in congruence. This is not only world class repair, but something most mechanics are not willing to put in the effort.
I think Eric is a great tech. He’s smart, but what sets him apart is the methodical scientific approach to isolating the problem.
@@JoeMama-j7sKnowing how to use them is more important.
I've worked, in automotive shops for 20 years. I've seen good mechanics, great mechanics, Mr. O you are by far the best I've ever seen. I've known mechanics that pass the ASE exams with flying colors, but they still have problems just doing a coolant flush.
That was not boring at all. I love your excitement when you discovered the banging on the sensor and the improvised "stethoscope" to let us hear it. Your ability to take complex data and simplify it to reach a diagnosis is impressive.
I have to put this out there - SMA is the best auto mechanic channel on YT by so much, it's crazy that some other guys have more subscribers. Must be that those guys still have subscribers from years and years ago, when they had the field to themselves. Eric O has got to be the hardest working man in the "working and making a video at the same time" business. This is another good one.
Some (well one in particular) I suspect has so many subscribers due to folks watching to laugh AT not WITH the "expert mechanic" and his opinions!
@@keithcurtis6671 Hmmm... Could that be ol' Scotty?
I ❤ Eric, but Diagnose Dan is the best, if Eric starts pulling EV batteries apart he will be equal.
It amazes me how many shops with "mechanics" don't do the basics of diagnostics and simply throw parts at it. Especially a lot of them on RUclips, great video as always Mr O!
Not even so much that, I'd completely accept a garage not being able to diag this fault. In reality your likely not finding that without a scope.
The issue is who's paying for all the guess work, yes it might be an educated guess, but the problem is how much has the customer shelled out for work that wasn't necessary.
The industry would be much better if garages were honest and said we don't know.
I throw the parts at it then take it to somebody that has a 5000 dollar scanner.Hahaha.
The problem is, the shop only pays the mechanic 1 hr and that’s all the time they get to diagnose a car and then pressed to give a best guess. That’s sufficient only for about 70% of the jobs. Other diags like this one need to pay more time but shops fear asking for more time and the mechanics get screwed over.
Most shops are hurry,hurry,hurry and fix it.Very little time to really think about it.
@@renewedautodiagnosticsllc1789 doesn't really apply here in the UK.
People are on hourly in terms of if they have a bonus system their hours are tracked, but no garages pay mechanics based on hours booked out.
You earn a basic salary for doing your job
Fantastic diagnostics on this one. You combined visual inspection, electronic inspection, tactile inspection, and testing your hypothesis and followed the evidence to exactly where it led instead of guessing or giving up because it was a pain in the butt. This is a true lesson in how diagnostics are supposed to be done. Very well done!
Super impressed with your diagnostic skills Eric. This was not at all boring, held my interest all the way. Your ability to actually show us what's happening is a huge plus. Thank you.
And who knew he could read Hebrew?!
That Eric O. is FULL of surprises!
Agree. Thanks.
I'm amazed at the pain and sacrifice you will go thru to bring great content to us. Thank you for information we can't get anywhere else.
The extra steps to make what you see and know obvious to the viewer is no easy task. Kudos to you and your channel sir.
Good job my man! Great diagnosis and camera work. Really appreciate you bringing us in on this one.
Your episodes are of Great Value to anyone who is/was in the trade. We have all run into that problem vehicle that has us banging our head against the wall. The art of diagnosing and explaining the steps is a Great asset to you and your shop.
These episodes are my favorite. Thanks for keeping us entertained, Eric. We may even learn something from time to time.
I don't understand how that is not a sensor correlation or performance error. The PCM should know and keep track of the length of the pulses and their edges. They just aren't even looking for that probably, or it doesn't fit some idea of what a failed sensor or sensor error looks like. A loose reluctor wheel should be a failure that make it into the DFMEA.
What is a DMFEA ?
DFMEA stands for “Design Failure Mode and Effect Analysis.”
I suppose the slippage might be emphasized when hand turning the crankshaft. Still, odd that those waveforms aren't throwing some codes.
That was some of the best diagnostics I've seen. Very few people with that level of patience to find the gremlin. Well done as always!
Aside from his immense diagnostic skill, I'm really impressed at how his video skills have improved over the years. Impressive
This is exactly the kind of video I watch this channel for.
Great job troubleshooting Eric! As a former electronic technician on some of the world’s most advanced airborne radar systems, NOTHING was more rewarding than finding the “root cause” of an intermittent failures that others simply wrote CND! Kudos!
Honestly Eric your one in a million. You have an inherent interest in root cause analysis. This to me is your TOP #1 VIDEO OF ALL TIME. What's kind if sad is it took passes by 2 previous shops and tons of $$$$ before a true problem solver diagnosed it. Like I always say, when I need surgery I'm having my doctor call you in for assistance. Your the best man!!!
you're one
There has never been a better diagnostic video done. It very much proves that true diagnostic gets to the actual source and doesn’t melt the barrel of the parts cannon. From one tech to another,amazing job and analysis. Breaking it down for the viewers was spot on. 👍🏻
Eric that was the most entertaining show of not giving up, finding the problems that other shops cant. I just want to say you are one of the best mechanic that I watch on you tube. Keep the videos coming!!!!
Eric, you are by far one of the best mechanics out there. I enjoy your “boring” videos more than all the rest.
I have to say, your diagnostic skills are amongst the elite in this industry. It's always a pleasure to watch your videos. If all mechanics were like you then there would be not junk yards, except when they rust apart...A+ video!!
Came for the diagnostics, stayed for the carnage! Bravo Mr. O, superb work as always
gpddamn cars,,,they suck when they dont go
You should be teaching the next generation of mechanics! You know....the ones who aren't watching your videos. Great video!
This was Awesome! Actually showing the timing wheel and how it relates to the two big and two little spikes on the scope, then following it up with the bore scope inside the sensor hole was awesome!
On so many other diagnostic videos I don't understand what the sensor is telling us.
So cool to have a confirmed diagnosis too, your work and your videos are top tier.
Excellent job! As a fellow mechanic, your videos are always intriguing. From diags to brake jobs, you’re the standard! I send your videos to young techs getting started. The small details you include, that take years to figure out is invaluable to this industry. Much love Erik, many blessing to you and your family ❤
It's the small details that make me a junkie for his content.... I've learned so many cool tricks watching his vids.
You outdone yourself with visual aids on this video Eric! The excitement in your voice when you saw the vane phaser move out then in was gold! Seeing the smoking gun, especially an unexpected one clearly brings you some joy. It is a good feeling when your day brings you something new - even when you have been around in your job for a while. Great work Eric 👍.
Solving a difficult problem always brings that endorphin rush.
I’d have to say, if there was an award from RUclips of great video techniques this video would be a front runner!
Eric. I love the fact that you are so humble. You are a brilliant diagnostic technician. It was great to see the digital problem and the physical damage that was causing it. This is one of your best vids. Far from boring.
What a great and entertaining video. I am no mechanic, but I enjoy these videos so much. I enjoy the "hunt" as much as the repair!
You did it again. You elevated yourself far above the rest of the crowd. The real value is not so much your tools, it’s you and your experience. Very impressive.
The number of shops the car has been in prior to yours is testament to how good you are at diagnosis. Great job!
Superb thought process and diagnostic, Eric! That timing disk is completely loose. No parts cannon would solve this - only a scope could give you insight on what was going on. Well done!
Top notch! As a home remodel/repair contractor, I never would have found this, but I'm thankful folks like you exist who are willing (and able) to track down the root causes. I try to do the same in my field, instead of smearing lipstick on the pig's behind and letting another sucker kiss it, and you're an inspiration to that. Thank you!
Eric as it has been mentioned, this type of video is the reason many of us watch your channel. Thank you so much for bringing us along.
You are so much more animated and involved when the problem is complex. Electrical issues are so much harder and challenging than something like brake repair which you were bored with a couple of weeks back. Thanks for taking us through your thought process. Great instruction in moving the problem way down the road! Thanks again for another great video!
Yeah, he even said "Lemme just check this one thing before I go home for the night..." and then he's taking the tire off, running a borescope, and turning over the engine. He was about to go home but he knew he was close to figuring it out and he was just as excited as we were to get the answer.
EXCELLENT video. The old saying is true, "Third shop is a charm!" This is proof that AI will never replace technicians. I always love a video that starts with "no codes". Those are the best.
The same goes for pilotless planes or cars for that matter. Take a driverless car on a windy mountain road with adequate line markings and you will end up crashed because AI can't keep up. The important part of landing a plane is dealing with wind variations and a computer cannot react like a person can.
In reality this car would be destined for the scraper if it can't be fixed. The eventual way repair work is headed. (throwaway society)
@@larrybe2900 Everything gets thrown away eventually. I got called very dark when I was sitting in a room and said everything in this place will be disposed of in a small period of time (including the people).
The car is 12-13 years old. It lived a useful life. Is somebody going to put timing chains on it for 3-4k? Maybe, maybe not.
As someone who loves nitty gritty, how-it-works, behind the scenes parts of life, I love the case study videos.
I also love the videos where the Dawg has to come out and just abuse some rusted junk down to generic brake jobs.
I learn something every time. Keep it up, SMA!
This video is genius without trying.
Man. You are the true definition of a mechanic. Not many around anymore. Remind me of my dad, just no yelling lol.
Th3 only thing I can say is “wow”, what a skill ! There are over 50 thousands parts to build a car, you, right away point to the right direction, absolutely amazing.
It's interesting to watch both you and Ivan when you are doing diagnostics and see not only the process, but hear the thought behind it in a manner that is super easy to follow and understand. Even more so when you show us the problem as it's happening - which isn't always easy to do, but it explains it far better than anything else.
You’ve got to be one of the best diagnosticians around. People are lucky they found you, but would have been luckier if they had come to you first.
This channel has some of the best procedurals. I swear you could make a series of diagnostics like this and sell it to the networks as a reboot of House MD.
Him and Ivan from PHAD.
Never boring to watch Eric work through a complex problem. Great repair.
A workmate had a similar issue with his brand new SAAB. It would die randomly sometimes restart others not. After having been towed to a bunch of shops over half the country it was bought back to be thoroughly examined.
They found the cause, a loose or missing nut on a ground lug under the rear seat (multiple wires)!
Love the channel even though I'm not all that interested in vehicles. I'm IT and electronics so I greatly enjoy the troubleshooting videos like this one. Your knowledge of the electronics, sensors and communication systems in a vehicle and how to use meters, scopes and other measurement tools to troubleshoot along with a systematic, logical approach to isolating faults sets you apart from most mechanics. You are among the best in the business and on this platform. You're a great teacher.
Thanks 👍
Great vid. But why were no codes set?@@SouthMainAuto
The people that live in your area are extremely fortunate to have a person with your abilities & help.
Thank you for producing your videos.
The next time my car breaks Im going to haul it up to SOUTH MAIN AUTO. I live in OK. no problem!
that is probably why he is booked out so far he is honest and doesn't just throw parts at it so as to make more $ of the customer
Me too, I live in Finland.
Wants feel that you know nothing about cars? Watch SMA. What a display of brains, determination, hard work, and critical thinking. Always amazing.
You make it sound logical and even easy. I can follow your thinking but the knowledge of how all the digital electronicals work is irreplaceable. You are NEVER boring to learn from. Thank you Eric.
That video was the farthest thing from boring! Extremely interesting diagnosis from a goofy waveform, to an obvious rapping sound, and finally the visual confirmation of what was happening. Kudos Eric and yet another reason why you have such a loyal following on RUclips.
as a kia master tech, these types of videos are my favorite to watch! huge amount of respect for you sir!
Do Kia Mater Techs use an Automotive 4 channel PicoScope on the job to diagnose vehicles?
@@windward2818 yes we do. we have a one that hooked a up to our own scanner
This man is a genius and gentleman. Prove what is wrong, then fix the problem. Don't just throw parts at the problem
Your ARE THE MAN ! ! ! !
NOBOBY else would have done the in depth examination you did!
KUDOS ! ! !
WOW! I absolutely love your videos where you work through the toughest problems to get a diagnosis. Do more like this!
Absolutely fantastic diagnosis. I'm a retired automotive instructor. The process and explanation is extremely valuable.
Eric, I am the president of your fan club!!!! I love watching you in your happy place.
This was amazing! It's not surprising to see other shops that couldn't diagnose it, but it's incredibly sad to see some of the cannon parts that were thrown at it.
I cant say I never threw parts at a car to try to fix something but I'm atleast in the ball park, spark plugs and ign coils for a car that's stalling 🤔,
Brilliant, truly excellent the way you found this fault, great video as usual, I have been a mechanic for 35 years and I am still learning stuff everyday. All the best from the UK Thanks Eric 👍
Wow - how is an engine with only 100k miles on it needing such a massive repair already? Great work Eric on finding the cause and using some deductive reasoning. Even though I'm not a tech, I enjoy watching you solve these strange problems
Really hope this woman didn't pay for the other work that was done. If she did, I'd be fighting to get my money back. Nothing against the mechanics, they tried even if by just guessing.
Good job and thanks for showing and educating. It's good to learn these things.
Brilliant work Eric. In my work as as a HW (electronics) design engineer I'm often tasked with debug and root-cause analysis of hardware and firmware and it's often the most enjoyable part of my job: Catching your "prey" after a good "hunt" is most satisfying. Your systematic, logical approach, taking a step back and seeing a ten-thousand-foot view of a problem to really root-cause it is so refreshing in an industry where the parts cannon generally seems to be the weapon of choice.
Absolutely phenomenal diagnostic skills and knowledge.
Definitely one of the best videos on RUclips right now.
This is so much better than a brake job video. Great diagnosis and skills. For a small shop you have a very well equipped shop. Anyway good job Erik
@0:17 - "it's gonna be kinda boring"????? I say "Nay, nay!" Best video you've ever made! This level of diagnosis is superlative. No parts canon required.
As an engineer, love the problem dianosis. Keep em coming.
As a retired engineer, I agree. Eric comes about the closest to using good engineering troubleshooting skills as any mechanic I have ever known. And he is very competent in many skills, mechanical, electrical, electronic, welding, etc. He reminds me somewhat of Dave Engel at Engel’s Coach Shop in Joliet, MT. They work on completely different things, but Dave is similarly versatile and logical in his approach.
As a former Electronics Technician and a currently semi-retired Electrical Engineer (as well as a shadetree automotive tinkerer), I found this video to be extremely entertaining and informative. I still get that giddy feeling when I zero in on a fault in piece of equipment, and when you saw that cam phasor reluctor flopping around on the borescope, I had an inkling that you felt the same feeling. I thoroughly enjoy your videos, and I wish I lived closer to you (I live south of Pittsburgh) so I could glean some of your wisdom. I would definitely bring my vehicles to you! Keep 'em coming, Eric!
Determination is a great strength. 8.00 pm and still hard at it. I think we all appreciate your skill along with your work ethic. Thank you.
Eric, this is a pretty new video and yet here I am watching it again! I'm not a mechanic, I'm just a guy that loves when someone like you finds the problem when two other shops just loaded up the parts cannon. Keep em coming Eric, you are the man!!
What truly separates a great all round mechanic and a parts cannon mechanic ...Eric O takes his skill and knowledge to another level to diagnose a problem ...brill diagnostic video ....as for tracing the problem i would send it to Eric O first 😅😂
I have to admit with many comments about how wonderful it is to see your diagnostic and thought processes. You’re skills are definitely top tier.
As a retired electronic technician, I find this kind of video to be my favorite. I have always found the hunt to be far more enjoyable than the actual fix. ESPECIALLY, when others before me have tried and failed.
Fascinating video!
How do you keep from being swamped with overwork?
This video is so good that when I accidentally started rewatching it, I didn't move on to something else. This is perfect example of "real world" crap that goes wrong and can ruin a household if there weren't good shops & techs
Now this is a real mechanic at work. I can’t believe 2 shops are just throwing parts at it, without knowing what’s really causing the problem. You just showed us (again) the difference between a mechanic and a “parts changer” as we call it in my part of the world!
The scope and camera are essential to do this fine job! Keep up the good work! Greeting from the other side of the pond….😁
99.99% of mechanics would not be able to find this problem😉.
@@mph5896 I’m aware of the complexity in this problem and diagnostics in general, but that’s not an excuse to not dig deeper instead of throwing parts at it. Most mechanics are not really interested in their job and try to solve problems the easy way by guessing….
Many shops allow their skill at "assuming what is causing a problem" rather than allowing their thinking pattern to start with the basics gets in the way. I realize that "shooting parts at it" takes less time and effort, but if you didn't fix the problem, what good were your efforts...other than making "parts markup" money for your shop? I'm 80 years old and long since retired. In an electronic engine repair, I'd be lucky to find my butt with two hands searching, that's why I leave the repairs to good shops with repair people who are qualified to work on them. I was a fire vehicle mechanic but retired when technology passed me by.
@@georgewhiteman7341 20 years ago the fire department I was doing paramedic clinical with had a new engine that would shut down every time they went to pump with it. It was equipped with all the new electrical technology instead of the old manual pto. They had it in for repair multiple times but it was intermittent so😅. Nothing like a limp hose when you have a roaring house fire🙃
I absolutely LOVE these kinds of videos. Its like I'm watching a free diagnostic masterclass. Awesome stuff, and thanks as always, Eric!
Not boring at all! Your enthusiasm finding the actual issue shows!
The way you took us from the beginning to the final discovery of the problem is perfect. I am a mechanic and the whole time I was armchair troubleshooting right along with you. Awesome video!
Same here !
Wow...that was really something. How could the right tire needing air break that cam trigger.....LOL! Great job finding the problem. Total respect for you an your abilities to not just throw parts at a problem. You always take the time to find the problem, then fix it. Big pat on the back Mr O.
Absolutely brilliant. Patience and knowledge pays off. If I lived in your area, you'd have earned my business from this video alone. Incredible.
Excellent diagnosis. These are the stand out episodes for me. Thanks for bringing us along.
And it all gets done with superb audio in a challenging "set" as well.
You were #1 on my 2023 "waiting to view next episode" list.
This is diagnostic work that probably 95%of techs out there arent able to do. I found a local guy who is honest and good but Eric is next level and there just aren't but a handful of techs like him in this industry. Very awesome video. I love this!
One of your best videos when it comes to diagnostics. You traced the problem, proved it electronically, then double proved it mechanically. Excellent work once again.
I wonder how long it would run with the sensor unplugged?
Hope we get to see the repair!
Thank you for showing us technician guys our ability to do a thorough job and how to diagnose intermittent signals and use the right equipment
