What makes this guy arguably the GOAT is a diagnosis like this and the fact he can also cut a rusted nut off a bolt with a torch and not screw up the threads and he is funny and honest and shares all this stuff with the common folk.... A legend...

The other shops in the area must sleep at night knowing Eric O is there in case they can’t figure out a problem.

As a former HD Truck/trailer technician, I can really appreciate your point to point diagnostics and your explanations. And you explain it in a layman's terms. Thanks for wonderful, informative videos.

What a blessing you are to the other shops knowing they can drop a car off to you to get a diagnosis when they can’t figure it out themselves! 🇺🇸

I have been watching you for several years now. Your diagnostic skills are awesome.

So nice of the other shop to change the spark plugs for a timing code...hopefully they rotated the tires too! Great job as always, Mr. O

Loved the line about chain stretch but we’ll use that term loosely 🤣

No Eric, you can do it, i can't. A person would need more than a casual experience to understand how these systems work, then interpret what the data means, providing you had the equipment. These cars have reached a point, where the average shade tree mechanic can install the easy parts via the parts canon. if the canon shot didn't hit the target, you can only hope the garage that you selected is as good a you.

I would have like the cover pulled to see the actual problem. Your adapting well to the increased electronics they're adding to these engines. You have become a expert diagnostician! The other shops know this too!!

One thing that did seem odd to me is that the engine did run pretty smooth, so I wouldn't be surprised if it's the sensor cam trigger that has moved.

when the other shops can't fix the problem they send the vehicle to south main auto 👍

Mr.O. You are a lucky guy to have Mrs.O. She should have her own KZfaq Channel.

The other shops “diagnostic fees” are just the tow bill to SMA.

My daughter has a 2021 Kia Seltos with about 70,000+ miles. She bought it new. Her engine light came on and the car stalled but restarted. She took it to her usual shop and they said it was showing codes P000b and P0017 and should go to the dealer. She brought it to the dealer, and they found the exhaust cam phaser was loose. It must have also damaged the cam because they replaced both the cam and the phaser. They also replaced a couple of oil seals. The work was done under warrantee at no charge to her. Her car is running great again. She got lucky it was still under warrantee. It was the first trouble she had with the car.

The fact that you verify your diagnosis sets you apart from a LOT of techs. It's amazing to see how many parts-cannon cars you get to work on. Now I will ask this question again (someone out there should be willing to answer it): How can a shop/mechanic charge the customer parts & labor for a job/problem that they did not fix? If I hire a plumber to fix a leak & he replaces parts that don't fix the leak - why should I be expected to pay him?

2 of my favorite channels are SMA and Pine Hollow Auto Diagnostics

The scope doesn't lie! Hope this isn't another twisted camshaft like the one you and Ivan found. I saw that video. Good one Mr. O. Nice to see Mrs. O.

Great video. I was never a big scope guy back when I was working. After watching your videos (about 4 years now) I wouldn't get back on the floor without one. It saves a bunch of time (comp. tests alone) and with the A,S wave stuff is very affordable...🤓

Took you 4min in the Video to diagnose its problems and other shops sent it to you. You're really the diagnostic king! Greetings from Quebec Canada

As a KIA technician... there's also an issue with the camshaft dowl pins getting too far into the camshaft and causing the cam gear to rotate. These usually produce a camshaft correlation code. The only fix is to replace the whole cam, the adjustable gear, and of course, at that point, change the timing belt and tensioner. The wholes for the dowl were machined too deep and allowed the pin to sink too far into the cam. They don't quite sheer off, but they deform and kinda bend sideways. I learned this from one of the Master KIA techs.

Your diagnostic skills are always impressive but sometimes your understanding of modern engine technologies is even more so. I looked at a new Kia hybrid yesterday but watching this makes me want to start looking for a couple 60s and 70s cars and buy something I will understand and be able to work on like the old days. Modern cars make me feel so inadequate. Your customers are so lucky to have you.

Eric O’…We love it when you get the Pico out and show us Waveforms!!

Can I come up there from Georgia for a summer and pay you to stand there and watch you and learn? Cuz your knowledge is astronomical.

Its always cool to see you use the scope and go though your process to find the issue, i hope to see a follow up, thanks eric

Shocker: the codes, which are made to tell you when the cam is out of time, told us the cam was out of time 😂 Good video, brother! Keep up the great diags. Im Learning every day!

Been watching for years. I've picked up a lot of diagnostic practices from this guy. I know it's saved me and my customers money over the years. Imagine if this customer brought the car in before unloading the parts cannon.

Wow, now that is some technical stuff. As a DIYer, I hope next week you can show how you work on the flux capacitors. 😳

It's amazing to see you're getting 100k+ views on your vids just a few hours after posting, that's more than the whole population of Steuben County, Your content and editing keeps getting bettter and better, keep it up Eric, 1M subs are around the corner big milestone ahead. Kudos!

This guy says he didn't do so well in high school. And here it turns out he's a super-genius. And he would deny that but its true. What really seals the deal is that he's a great teacher and as near as I can tell he's a super human being. My favorite channel on KZfaq

You, Sir, are the Wizard of auto diagnostics!

You are a very good teacher. I wish my college instructors were half as good as teaching as you are.

The dry door hinges says it all on maintenance

The way you say "You/We can clearly see"... Idk why but it triggered a memory... In The Princess Bride, Vizzini and Westley are having a battle of wits and Vizzini repeatedly says "clearly" many times during his thought process. This just reminded me of that! 👍👍😂

Would it have been an interesting idea to scope the solenoid control signal? Your videos are great, I hope you do not loose interest in posting new ones!

As an old drivability tech from the 90’s and early 2000’s I love watching this stuff.

Great video and Diag. Eric as always. Those other shops are fortunate to have you to be able to help them out, as well as the people who live there.

Brother, I for one are jealous of your knowledge, keep teaching us what we don't know.

Love these diagnostics videos!

Sad too that Kia has made hundreds of thousands of cars and this fault probably has raised its head many times, but will they let the public know? Thanks Eric for you most enlightening and entertaining work.👍

Another great diagnostic video Eric. O. Always a pleasure to watch what you do best.

Love the chill shout out to Ivan. The old TWISTED CAM HYUNDAI.

Since you are smart enough to diagnose this the customer should opt. To have YOU fix it!

Love that twisted cam vid. Did not expect that

Great diagnosis and your description is clear and animated enough to keep the attention.

Great video man as usual. Love this kind of stuff.

Great diag.! Love following along , tests my self taught mind ! Thanks !

Always nice to see Mrs. O.

When something throws that many cam timing codes and has a chain, its almost certainly a stretched timing chain or broken guides. Super common problem on multiple engines. Stretched chains are not always noisy. Typically, if you want less chain wear, change the oil at decent intervals, not the bullsh1t 15,000km's /10,000 miles.

thats cool Kia figured out how to make a chain last no longer than the belt it replaced... Now that is engineering

Yo Eric make sure to give us an update on the Kia. What was causing the issue after all. Keep up the good work!!

The PID will drop from scan data because the reference voltage signal has open circuit too. Without reference voltage no valid data, if reference is provided.

You lost me when you started talking about pulling out your tri corder and using the phaser on it. I figured I'm out of my comfort zone in this video. 😀

Your experience pays off. Keep up the good teaching sessions.

Once again, you went above my pay grade. Even if I had the high tech gizmos. At least I can still follow along and learn something. Thanks Mr O.

Hey Eric! Our '06 Sonata with the big 3.3 six was in the shop almost when it was new for upgraded cam chain tensioners, and Ed the mechanic said one cam was off, and that was when the car was a year or two old. This is my first and last Hyundai.

The best!! I’ve watched for years with much learning and enjoyment!!

After market Phaser sounds like one!!

As a diesel mechanic and having one of these vehicles in my family I really appreciate your hard work and showing and explaining your steps in diagnostics 👍🏼

Thanks again for such an informative video. You demonstrate the how and why so well, and how valuable a PICO scope and known good waveforms are for diagnosis.

I have a 2015 Kia Soul Exclaim. It has 90K miles on it and I’ve been having trouble with it for over 10K miles. Got a new transmission, new spark plugs. They told me the last three oil changes (I get done every 3K miles) that I burned just under a quart each time - but that was normal - that I had to burn OVER a quart each oil change to be considered for an engine replacement. Some time ago - I did get that software update and they told me that increased my warranty to 150K miles, instead of 100K - but it was only on the “lower engine”. This past time - they told me that I needed special seals on the car that only they can open in order to officially check the oil loss. I asked why they didn’t do this at least two oil changes ago - and they couldn’t answer. They did say on my receipt that the oil they took out was dark and burned looking. So - this time they did the oil change and some sort of combustion cleaning and they added some sort of additive that corporate says they have to add - along with the seals in order to start the process to be approved for an engine replacement (I though 2 oil changes ago I was in that process!). I asked to see the bottle - and couldn’t see any ingredients. My cousin said if it had Teflon or silicone in it - that would be like putting a bandaid on a bruise - it is only hiding the problem. So - brought the car home (it is my ONLY car!) and the next morning - when I drove it - there was knocking and shaking - so I revved the engine a bunch of times and it went away for that day. Worked from home for a few days - then had to go out at 5 a.m. this Monday. Drove out about a half mile and it felt like I was going over a million large speed bumps. Revving didn’t help - when I would slow down for any reason it felt like the car was going to stall. Then when I would speed up again - it would bump terribly and I felt like I was fighting the gas pedal to get it to accelerate. I had a medical appt I had to get to - so made it to that - and then drove straight to the dealership - which was about 2 miles away (getting to my medical appt was 45 terrifying minutes). I walked in, embarrassingly, burst into tears, and they took it back to look at it. The advisor came out 10 minutes later and told me I had “scoring” on my cylinders and that I had been assigned an advisor that was going to contact corporate immediately for an engine replacement. He told me the car wasn’t safe to drive - that it would “sieze” up on me on the freeway. Five minutes later, he called me to the front desk and told me he had “great” news. He said I had passed all my “combustion tests” (I don’t even know what those are) - and that the little “scratches” on the cylinders was incidental and was fine. He then said they knew what the problem was and - sort of in a “gotcha” way - after I said - ok what is the problem - he lifted up a small container from behind his desk - slapped it down in front of me - and loudly said “You put bad gas in your car!”. He said gas should be perfectly clear and he said this gas was slightly yellow and he said it had 22% ethanol in it - instead of 10%. I said I went to a major gas station that everyone goes to and how could this be. So - I asked for a manager and I told him I couldn’t afford a rental car - so he agree for scaring me saying the car was not safe to drive - they gave me a loaner and they are flushing out the fuel, cleaning, then refilling, and doing another oil change. He said all I have to pay for is the $30 fuel filter. I asked if the “combustion cleaning” and additive they put in last week could have anything to do with this - because I said aside from burning oil - before they did that last week - my car drove just fine - no shaking, bumping, or flashing/solid check engine light. He said no - that was not it and when they turned the car on when I brought it in just hours before - they said the check engine light was not on all. He finally did admit that cylinders 2 and 4 were having problems - but that was because of “my” bad fuel. He said I needed to get in touch with the gas station and tell them their fuel was bad. Then he said I needed to call them and give them the gas station manager’s name and number. I did all that. Now it is Wednesday and I haven’t heard a peep. I am scared they are trying to mask whatever is wrong - because they told me Monday afternoon - that once they cleaned the fuel lines - that everything would be fine and we’d be back to checking the oil from under the seals every 1K miles to see if I burn more than ONE QUART in 1K miles (the story was every 3K miles, now it is 1K) - so that I can be “considered” for an engine replacement. I’ve got 2 years and just under 10K miles left on my powertrain warranty - are they trying to drag this out so I don’t need the replacement until it is my responsibility? I can’t afford to trade this car in or get another car for at least two years - so I am so worried - I did overhear (I was around the corner - he didn’t see me) - the service advisor on the phone sounding exasperated with a customer - saying “You will have to be patient, you are SEVENTH in line for an engine replacement.”…..so I wonder - they don’t want me to be the eighth? What words can I use to make sure my and my family’s safety is the number one priority when they give me my car back - and they tell me it will be ok? Thanks for any advice.

I always enjoy your videos and wear my "South Main Auto Repair" swag with pride. Thanks for this and all your videos. Be well!

Another Great Video. Hope the original shop gives you credit for being able to figure out the timing problem when they present their findings to the customer. Also, must be nice to know that other shops look up to you to figure out things they can't figure out. Love your video keep them coming!

Stretching a chain…we use that term loosely! 😂🇨🇦

Got it! Well explained! You have a classroom right here on your channel! Thanks for your time!

I noticed Mrs. O's shop coat was awful white and was missing the South Main Auto Shield on the back. Great Video Eric!

Great teaching lesson. I love the video. Take care, thanks 😊

They don't call it the money light for nothing. Montana registration should fix this right up.

Good diagnostic path Eric O scan data can throw you off if you rely on it definitely looks like the cam pid went dead when the cam codes set 21:27 @South Main Auto Repair LLC

Great video and explanation of your diagnosis as usual guys!

Agree with you Eric, had a Toyota Highlander same issue. Found timing guide bolt and other loose.

When other shops just can`t figure it out, they send the vehicle to South Main Auto so Eric can figure out what in the thunder is going on. As usual, Prof. O. never disappoints. And explains it so we who know enough to get our butts in trouble, can learn. Thanks Prof. O.

Great explanation, I was able to follow precisely. Appreciate all you do!

Excellent clarity...tools and knowledge is power. best DVD:)

Its always a good day to pull out the scope and have a look. You can only get better at using and reading the signals.

One word i can think of for your work and experience. AMAZING!!

All scope diags are 👍🏼👍🏼👍🏼. Thank you, Eric.

I think Ivan had one where the phaser had shifted or was installed wrong and was degrees out. A new Cam fixed it.

The phrase "If I can do it, you can do it" sounds strange when another shop couldn't do it

Thanks for the video Eric.

Another great video you are the best diagnostician I've ever seen!

Excellent teaching!

Amazing diag. Eric! Your the man. Great video.

What you tested made sense and now you have to start taking parts off. Nice Job!

3 minutes in and already have an idea of what this is going to be. My Kia had same signs and symptoms at 104k miles. Timing guards are plastic and wore out . Had it repaired but the motor still failed at 118k.

"The money light is on." Gotta love it.

Keep us updated, thank you

As an advanced tech for Toyota I’m not mainline so I don’t do much with diags. I do brakes, tires, certain repairs, aglinments, some diag not much, and other minor things but one day I wanna be mainline and your videos are a world of knowledge getting me prepared so I Thankyou for the videos

I like it when you get in the details of the pico and how to use it!

Between South Main Auto auto and Rainman Ray…it’s the best stuff you can watch on youtube.

Great video Eric . your very knowledgeable Sir!.thank you

Hopefully we get a follow-up if the car owner decides to repair.

Excellent diagnosis my friend

CSI Eric on the Kia. I am a consumate learner and I appreciate your ability to help me understand at my novice level. Thanks again. I did a complete head gasket kit repair on my wife's 1998 Buick Century. Took 2 days..heard the eords in my head.. " if i can do it, you can do it"..and yes it runs awesome..thanks

Another great video Eric.

Great video Eric O

Eric, Thanks for the insight! What about closure? How am I supposed to sleep at night not knowing if it actually fixed it. I mean I trust you more than any mechanic I ever knew but at least tell us? We trust your honesty!

Love this video.i learned something.

Exact problem I had about 6 months ago on the wife’s 09 Sedona with the 3.8. Went through everything like you did even though it can feel like a waste of time always good to double check and not bring out the cannon to launch parts at it. Unfortunately all routes lead to giving it the works in the yard with a full timing job. Runs like a dream now though.

That was a good diagnosis. Fascinating

Thanks for the Scope work Eric!
