Awesome video, Keep up the great content. Huge favor to ask, may I have you please update your download links. I have similar engine that I'm working on P0016 and P0017. Thanks in advance for your efforts.
Hello - got code of p0016 on my 2.0 Ecotec turbo engine so just the intake camshaft timing off with respect to crank shaft. Not getting code p0017 which would be the exhaust camshaft off too. So thinking then not timing chain problem say jumped as would get p0017 too. Replaced both camshaft actuators and still problem of rough engine and cel still showing just p0016. So could be the reluctor on intake camshaft or maybe the intake camshaft timing sensor - u think one of these most probably? Thanks for any ideas.
Nice case study , I was trying to download the waforms to play with them but a message say , "No available . 404. That’s an error. The requested URL was not found on this server. That’s all we know. Thanks for sharing Eric .
I enjoy all your videos. I usually do not comment, as you have many subscribers with comments. But I found this to be an exceptionally good diagnostic video. The pressure waveform data complimenting the cam/crank data was great. Thank you for sharing.
Excellent! Diagnostic skills deserving of a brain surgeon. I salute you for working for an owner who wants to do his own grunt work. Most shops want the customer to commit to have the work done or they will not share any diagnostic data. Of course, some of those shops are guessing and don't have the skills you have. Of course in the end the engine has to come down at least as to the timing "drive" gear level, which on these transverse engine layouts is a nightmare. Thanks for a great, informative video!
@@jamespn the average Joe or Jane can do this. Get a scope. Most techs already have one and don't use. If you have a Verus, a Modis, or even a Vantage... you have one. Just start playing around with it. Start on known goods... get out to training events. TST is in a 1.5 wk. Get on AES wave, order a John Thornton class which arrives on a USB. Eric has proved ANYONE can do this. He's not a college graduate. He's mostly self taught. Get out there and try it! 😊😊
After every show, Eric says, “Remember, if I can do it, you can do it.” Stop thinking you can’t and watch what Eric does, take notes, and start at the beginning, with your next job, add in the time to do just one more thing, and build on that.
Same here. This guy is a cut above. I stumbled onto his channel just trying to peek ahead to intake gaskets on the mini van. Probably tied for my favorite channel with AVE.
I'll bet your school teachers would be extremely surprised! You turned out to be a pretty smart fella! Your grasp of the info contained in those waveforms was quite impressive. THANKS AGAIN for great informative videos.
At first, I thought that Mr. O had been replaced by a pod person, but then he troubleshot the car and I realized that he had left his hat off... Thank you for a very interesting analysis, thumbs up!
Thanks Eric O. These cam/crank collocation videos using the Pico and cylinder pressure test are very helpful. Thanks to you and others, I'm no longer sitting on the fence debating with myself what bi-directional scan tool and scope to purchase. Purchased the Autel 908 and 4-channel Pico scope yesterday. Should be on delivery truck today.
Eric you are a damn good mechanic, very knowledgeable and very humble. You are always willing to learn more and trying to be the best mechanic there is and if you aren't youre damn close. Thank you for everything keep up the great work.
That observation about the exhaust valve closing early, and what it means to the reality of the cam timing as opposed to the instrumentation, is truly the mark of a guru!
You are getting spectacular at these diagnostic presentations! My bet is that only 15% of domestic auto mechanics in the USA use a scope in their diagnostics. The Pico compression analysis was very interesting. Confirmed advanced timing as the Exhaust valve opened before 180 degrees, in your diagram at 25:12, thus drawing a vacuum in the cylinder on the piston down stroke and the exhaust valve closed before 360 degrees, in your diagram at 25:12, which built up pressure in the cylinder before the intake valve opened at 360 degrees for the down stroke of the piston. Neat stuff! (I am not a mechanic).
Working flat rate, most of the time you're only going to get paid an hour to diagnose a problem. Pulling out the scope setting it up there's at least 10 minutes right there. If you were a mechanic you would understand why we don't spend what little precious time we have to use a scope and be 110% sure of our diagnosis every time. It's pull in the car, find the problem as fast as you can, pull it out, on to the next one. Otherwise you will go home poor.
The way you explain things is very clear to me thank you for sharing your knowledge and going the extra mile to show all the other possible ways to confirm your diagnosis. Great video as always
Jobs like this make you realise just what an amazing resource the Pico Scope is. After reviewing the online support you realise it is an absolute bargain that you can't work effectively without. I would be lost without it!
This is the best automotive repair video I remember watching. Only clear, accurate, pertinent, and complete information, well presented. Excellent videography. All it's missing is quirky sound effects and maybe a funky wig for entertainment value. You're getting pretty good at this. Thanks again for the great vids.
This might be the best diagnostic video you have made. You are able to teach in plain English and go through the steps of your procedure in an organized manor. I was especially amazed by the second half of the video where you demonstrated the use of the pressure transducer. What a gold mine of information the waveforms from the transducer produced. I think any tech that is involved with diagnostics at any level would benefit greatly by watching this video. Good job, man! Thanks for sharing.
In my experience with these Ecotec engines a P0016 indicated the timing chain has skipped a tooth, mostly due to the front guide upper bolt breaking and the guide getting chewed up.
This is 10/10 the best video on the SMA channel! The explanation of the wave form going to vacuum got me hooked and he whole thing began to make sense. I learned a great deal here.
Hey Eric, as usual I always enjoy your videos. One tip I want to share to you and everybody else is with the tech 2 cam data. This has worked on multiple impalas with me, if you have a timing code. Clear the code just like you did but DONT start the engine yet, pull up your cam data first then start and run the engine. Your desired and actual cam positions PIDS will display for a very brief moment (3-4 seconds maybe)until the codes trip again and then it will all defaults to 0 just like in the video. I’ve seen this fooled many many people
Nope. He's roughly a year or two older than me (I'm 37) we're both gray before 40.. Solidarity brother!! And.. Most importantly.. It's all still there..
I'm following this closely, since I've got a 2.4 Ecotec in my wife's 2008 Malibu. A few yeas ago I had a cam solenoid code and it really was the solenoid, but I can see myself doing the timing chain, etc at some point. Great video.
I don't understand how some shops operate with only basic tools and " training " - I've got a feeling in my big toe . How do you hang over $ 1000.00 parts and labor on a car and NOT fix it ? Then give the customer some dumb story - the car is old , it was was worn out anyway or it's a layered problem . The best one " the car can't be fixed " . What's wrong with it - " I don't know " . How do they get away with it ? Beware ANY auction vehicles ! Nice diagnosis . Training and tools , the scope , are an investment !
When you were showing your pico screen, and when that windows about changing your theme to improve performance came up, I thought that was on MY computer! I was just beginning to lean forward and grab the mouse, when I realized, oh, it's his!
I love doing chains on the 2.4L. I also liked how you covered that TSB. Great video as always, really cool to see both CMP/CKP & WPS to verify that TSB doesn't apply...always something to learn from you man.
First, much respect in this comparison to show an incorrect valve timing! I will definitely use this in the future. I just had to correct you at 24:45. You stated that the intake opens at the end of power stroke. I believe the exhaust valve opens at that time. (Hence exhaust stroke). Lol u are very thorough and I know I'm not perfect, but I had to mention it as it hung me up for a sec.
Dang Mr O! You showed that chevy who's the boss. No guessing allowed! Thanks for being an Awesome Tech and with a willingness to share and take us along. Hope you get the chain job so we could follow up with the actual visual. Seeing is believing and you show us all either physically or Electronically. Thanks again for time and videos and being so good to us!
Well, you broke out the professor thang GOOD JOB!! The power balance just blows me away. Please let us see the repair, I want to see what failed and keep up the great adventures, thank you. ,
the in cylinder pressures are so cool. im new to getting into the scope and just used it to find a timing advanced issue. im really interested in this in cylinder issues. would love to see more videos. you explain it very well. i know this is an old video but for the next video i recommend slowing down and either showing a known good and explaining more or taking more time to see what the pressures should be. atleast thats where i got a little lost. anyways i love all your videos keep it up!
HOLY SNOWBALL ERIC O. WHERE'S THE DECK LID? ALL THAT GRAY! From a fellow tech to another, keep it up, man. So far you're pretty much the only vehicle tech on TH-cam I can always agree with. I won't mention the others. LOL
Great video thanks for going the extra step and showing us in cylinder! Always good to have known goods! Hopefully you get the job. Looking forward to it.
Cool thank you I work at a GM dealer ship. I have replaced a lot of the solenoids due to those codes. But it's not always the solenoids at fault...I like how you went threw the steps to show how it's done right...so there's no guess work
Good stuff man! Boy does in-cylinder pressure testing make a compression gauge look dated! Amazing the things you can see in there. Never used one in person, but learning from all you guys out in TH-camLand - I did notice the pressure where there should have been vacuum, when the piston was on its way to BDC. A window into the engine! Great to be able to learn these things before I even own one. Wish the auto industry would use Apple products instead of buggy, glitchy Microsoft products. Can't download the PICO software on the iMac ... 😞 I've been sold on a scope for a long time now .. but then I get into these occasional dry spells where I get no drivability jobs coming in (like now), and then I continue putting it off. I'll get one eventually. I can justify the expense just having it for my own vehicles. Same with the J-box. Just pains me that I'll have to buy another PC to make it all happen. Windows drives me nuts! I seem to spend more time fixing its problems than I do benefiting from its use. I actually have no paying work today. Have 3 lawn tractor jobs I can't get to, thanks to the broken truck. Going to finish working on getting the Viair air compressor system leak free in preparation for the OX Locker. Fixed a bunch of leaks yesterday that I've been meaning to get to for 4 years now. Now to get out there and see what the pressure is after 17 hours - hoping it's the same as when I left it. Maybe I'll pull the axles today and install the new seals, and also install a couple motion lights on the shop that I've been meaning to get to for the past year. :)
A big switch from all the rust and crust...Eric O didn't get dirty?!? Mid diagnosis, I half expected him to say "Pardon me, do you have any Grey Poupon?" He just revealed to us all the WISDOM that lives up there under the hat. My father was always intimidated by electronics in vehicles. As an electronic tech myself, I've embraced it...but Eric really knows how to BRIDGE the GAP as it applies specificly to vehicles, in a way that makes perfect sense.
Saw this and thought about your Colorado Series when you tried to do the bidirectional control and clear the codes I remembered from that video what was going to happen.. I have two customers with this same car one is a 2010 and the other is 2012 if only I had a scope I could have sent some known good. Scope will be my next investment I just picked up an Autel MS906TS and I love it!!!
Once there was this kid who got into an accident and couldnt come to school, when he finally came back, his hair had turned from black into bright white
I don't know if you saw it or not but I had commented on one of your older videos but me you teaching handle better car and you were doing a lot of things and showing her things I just want to thank you for passing on knowledge I've been a butcher for 40 years and I've always passed on knowledge I've turned a lot of meat Cutters over the years and made him really good and I know how important it is for someone in our experience and everything to pass on knowledge
If you do what you love, its not work. I was snickering at the fact that your mistress is your work. You could not help yourself, and did not want to anger Mrs O. so you made up an excuse to sneak into the shop. Does Mrs. O watch your channel?... this may not be your best kept secret. So funny, it shows that you love your work! Probably why you are so good at it!!!
Dr. O, I started watching your channel about a year ago and had to go back and start from the very beginning. I immediately began to suspect you and your wife are Christian-by your integrity and how you conduct yourselves and your business. I appreciate that I can watch your informative, humorous, and always entertaining channel with my boys, which I would not be comfortable doing with some other channels. You and Vanessa are wonderful role models! I hope if I'm ever accused of being a follower of the Lord I will leave enough evidence to be convicted... God bless!
What an awesome video using the pic scope to diag the car. We do plenty of actuator jobs and timing chain jobs on these 2.4 . I haven't ran into needing that bulletin too much to be honest. thanks for showing great diagnostic skills and your really good at the pico scope.
Any ideas on code p0017 after replacing timing chain on 2.4L? Car idles great just has the code? Can’t find a solution anywhere on internet or mechanics near me
@@410AutoTech yes sprockets we’re changed and timing was spot on. After a lot of research I found specs for the camshaft and discovered that the rings had slipped an 1/8” thank you for the reply
Eric, Excellent diagnosis, explanation, and video - thank you. I like the 'sunday best' look on you (and a bit longer hair) - you look GOOD! Looking forward to a follow up video on the total fix for the ol' chivy. SMA#1 God bless Paul
Excellent information, I happen to own the same car but white in color. These also seem to have issues with the BCM connectors needing di-electric grease on the C2 connector near the front passenger floorboard. Symptoms of this can cause your brake lights to be illuminated when you are not on the brakes. Also, the brake lights will turn off when you apply the brakes...Also...Can make your thermostat gauge not work as well as the A/C Compressor.
I saw you with no hat on and I said WHOAAAAAAA who's that guy?! 😄 Just kidding. Eric your hair is really neat to be honest. I don't know anybody who is young like you with an awesome head of white hair like that. People buy platinum dye at the store to do that. :) Wicked.
Nice call Eric... replace the chain, all of the guides, actuators, phasers, and the tensioner... With ~144,000 on the clock just replacing the actuators and leaving the other components with probable wear will just leave the time bomb ticking... 💣 (I'm not sure if you're going to mess with the balance shaft chain and tensioner)... But I like to do that too while I'm there...☝ good stuff Mr. O.....
Wear that white hair proudly Eric O, you've earned it. My hair is all white and my prastor (who is bald) commented to some other church members last week, he would kill for hair like mine. lol He was joking about the killing part of course ;-) Always enjoy watching your excellent videos...keep them coming
Don't let everyone fool ya, Eric. Grey hair is a sign of wisdom (or, in my case, living with all women...but I digress.) I'm not a hat guy so I like the no hat look. I thought I stepped up when I bought a Vantage Pro but am learning that one really needs a 4 channel scope to do this simply. Fantastic video, Eric. Thanks for bringing it to us.
What an interesting video. I knew modern cars were complex but didn't know the complexity in diagnosing them. I would love to work on cars for a living but the knowledge you have seems like it work take years to get there. Enjoying the videos
Nice video Eric! I've always liked your channel, you take a problem and walk us through step by step in the diagnostic process and then if and when you get the job, take us step by step through the repair. I have to admit you make it look so easy but for me probing the ECM is so scary, cause like you said, if you probe the wrong one or cross the probes with a full 12 volts you just had a bad day. New ECM here we cum. Love watching you do this stuff. I've learned so much, thanks for sharing......
I appreciated the "Little extra fun" with the PICO and the wave forms. I'm learning a lot and look forward to TST as well. The screen shots and PIP were really cool. Sam has a good channel too. :)
Two things. You look great! And I’m taking you up on your sign-off. I bought a used camera, some lighting and mustering a little courage to try my hand at YT videos on my favorite hobby.
Great video. I hope you get the OK to do the timing chain on that 2.4 LE5 as I have an 07 Chevy Cobalt with that same engine. The car just flipped 75k miles and am not yet too concerned about the chain on it. But do plan on doing the chain on it when the engine hits 150k regardless if it needs to be changed or not as those are interference engines. The engine being an interference engine probably why valve timing can't be adjusted when those DTCs pop up because doing so might cause the valves to hit the pistons and now an easy fix just got worse. It's also a 5 speed, so when the clutch needs to be changed, I then plan on to take the engine and trans out and replace the clutch and chain at the same time if the chain hasn't been changed at that point. I take good care of my Cobalt and plan on driving it until the wheels fall off not because of rust, as I live in the south, but because of mileage or was wrecked.
Very informative video. I’ve done 2 of these engines with the same codes and both times it’s been broken timing chain guides. Especially the top one under the valve cover there between the cams.
@Case Knives He said he was driving by and decided to stop in the shop when he was probably technically on a trip to the store for the wife. lol. Eric, you better have got the wife her wine after this detour to your shop. Us on the TH-cam thank you though for thinking of us as well.
Eric, there is some strange guy doing videos on your channel with gray hair and no hat! He looks like a worn down Chrysler tech. He did an excellent video on a 2.4 with timing problems though. I learned a lot! Great video.
Love watching all your videos Eric. My question is how many scan tools do you really have ? My guess is 8 and how did you convince Mrs. O that you need another scan tool. Maybe you need to make a video comparing your scan tool collection. The Autel seems to be the best bang for the buck for the diy’er.
Hey bud, im working on a 1.4 2012 cruz and i got rhe p0016 p0017 codes. Hard start then it will throw xode on start up,but when it starts right up,it dont throw it. Sceeams to me crank swnsor but ive replace the crank and both cam sensors. Wont throw while idleing,just on start up. Looked at cam sprocks or where the sensors read, and they are good,chain is tight and cams aee still in time,i can slide the tool in the back of them. I cant make the accuators,accuate with a scanner,because of the codes.. i used a GM crank sensor,so no generic sensors. Ive worked on a few of em,but this one has me stumped.

Dang Mr O! You showed that chevy who's the boss. No guessing allowed! Thanks for being an Awesome Tech and with a willingness to share and take us along. Hope you get the chain job so we could follow up with the actual visual. Seeing is believing and you show us all either physically or Electronically. Thanks again for time and videos and being so good to us!
Well, you broke out the professor thang GOOD JOB!! The power balance just blows me away. Please let us see the repair, I want to see what failed and keep up the great adventures, thank you.
,
the in cylinder pressures are so cool. im new to getting into the scope and just used it to find a timing advanced issue. im really interested in this in cylinder issues. would love to see more videos. you explain it very well. i know this is an old video but for the next video i recommend slowing down and either showing a known good and explaining more or taking more time to see what the pressures should be. atleast thats where i got a little lost. anyways i love all your videos keep it up!
HOLY SNOWBALL ERIC O. WHERE'S THE DECK LID? ALL THAT GRAY! From a fellow tech to another, keep it up, man. So far you're pretty much the only vehicle tech on TH-cam I can always agree with. I won't mention the others. LOL
Still using brake cleaner for hair spray?
"The Good Stuff"
Who would you rather have working on your car, no gray or with gray?
@@InsideOfMyOwnMind LOTS of gray. We have to take a bunch of knocks before we figure things out.
Apparently it rinses out the Just for men colouring.
Who's the new guy?😜
LOL
Capless Eric!
He's changing his look, there are too many guys impersonating him on YT.
Might have to start calling him Q-tip. Just kidding Eric, it looks good on you.
@@fascistpedant758 🤣🤣👍
Excellent diag. Always good to see you cross-verify your diagnosis. You're definitely teaching lots of folks how to do it correctly.
It’s freakin inspiring watching you work and hearing your thoughts. Simply amazing.
Great video thanks for going the extra step and showing us in cylinder!
Always good to have known goods! Hopefully you get the job. Looking forward to it.
Has good news finally found a mechanic that is fair in price . It took me almost a year and half persistent does pay off .
Cool thank you I work at a GM dealer ship. I have replaced a lot of the solenoids due to those codes. But it's not always the solenoids at fault...I like how you went threw the steps to show how it's done right...so there's no guess work
Thanks, Eric. Always enjoy the scope vids. Hope to see the conclusion!
I really enjoy your videos, very educational and informative. Thank you
Good stuff man! Boy does in-cylinder pressure testing make a compression gauge look dated! Amazing the things you can see in there. Never used one in person, but learning from all you guys out in TH-camLand - I did notice the pressure where there should have been vacuum, when the piston was on its way to BDC. A window into the engine! Great to be able to learn these things before I even own one.
Wish the auto industry would use Apple products instead of buggy, glitchy Microsoft products. Can't download the PICO software on the iMac ... 😞
I've been sold on a scope for a long time now .. but then I get into these occasional dry spells where I get no drivability jobs coming in (like now), and then I continue putting it off. I'll get one eventually. I can justify the expense just having it for my own vehicles. Same with the J-box. Just pains me that I'll have to buy another PC to make it all happen. Windows drives me nuts! I seem to spend more time fixing its problems than I do benefiting from its use.
I actually have no paying work today. Have 3 lawn tractor jobs I can't get to, thanks to the broken truck. Going to finish working on getting the Viair air compressor system leak free in preparation for the OX Locker. Fixed a bunch of leaks yesterday that I've been meaning to get to for 4 years now. Now to get out there and see what the pressure is after 17 hours - hoping it's the same as when I left it. Maybe I'll pull the axles today and install the new seals, and also install a couple motion lights on the shop that I've been meaning to get to for the past year. :)
A big switch from all the rust and crust...Eric O didn't get dirty?!? Mid diagnosis, I half expected him to say "Pardon me, do you have any Grey Poupon?" He just revealed to us all the WISDOM that lives up there under the hat. My father was always intimidated by electronics in vehicles. As an electronic tech myself, I've embraced it...but Eric really knows how to BRIDGE the GAP as it applies specificly to vehicles, in a way that makes perfect sense.
Saw this and thought about your Colorado Series when you tried to do the bidirectional control and clear the codes I remembered from that video what was going to happen.. I have two customers with this same car one is a 2010 and the other is 2012 if only I had a scope I could have sent some known good. Scope will be my next investment I just picked up an Autel MS906TS and I love it!!!
Eric, one of the best I have seen you do. Great explanation and diagnosis for us. Thanks.
he worked on a Chevy and his hair turned white over night
Once there was this kid who got into an accident and couldnt come to school, when he finally came back, his hair had turned from black into bright white
@@grabasandwich Exactly but you know. he said that t was from when the CARS had smashed so hard
rimmersbryggeri Nice! 1993 was a good year👍
bobl78 got it that’s what happens when you work on a Chevy I’d hate to think what happens when you work on a junk ass ford
bobl78 you noticed it, too!
I don't know if you saw it or not but I had commented on one of your older videos but me you teaching handle better car and you were doing a lot of things and showing her things I just want to thank you for passing on knowledge I've been a butcher for 40 years and I've always passed on knowledge I've turned a lot of meat Cutters over the years and made him really good and I know how important it is for someone in our experience and everything to pass on knowledge
Thank you so much I've been watching your videos for 6 months or so now if I lived up in Upstate New York you would be by go to man
Awesome video Eric. Using pressure transducer is my favorite subject. Cheers 👍👍
I almost didn't recognize you without a hat!!! A sure sign of Spring!
Thanks!
If you do what you love, its not work. I was snickering at the fact that your mistress is your work. You could not help yourself, and did not want to anger Mrs O. so you made up an excuse to sneak into the shop. Does Mrs. O watch your channel?... this may not be your best kept secret. So funny, it shows that you love your work! Probably why you are so good at it!!!
Very thorough diagnosis sir. A bunch of great info as well. Thanks Dr. O!
Dr. O,
I started watching your channel about a year ago and had to go back and start from the very beginning. I immediately began to suspect you and your wife are Christian-by your integrity and how you conduct yourselves and your business. I appreciate that I can watch your informative, humorous, and always entertaining channel with my boys, which I would not be comfortable doing with some other channels. You and Vanessa are wonderful role models! I hope if I'm ever accused of being a follower of the Lord I will leave enough evidence to be convicted...
God bless!
At 16 I joined a rock and roll band. 6 months later my hair all turned white. God what a great time.
You love your work, and I love watching you do it. I'm glad you're no a dancer.
No hat. First class editing. Looking nice today. You look like the man. You are the man. Only getting better and more thourow. Great video.
What an awesome video using the pic scope to diag the car. We do plenty of actuator jobs and timing chain jobs on these 2.4 . I haven't ran into needing that bulletin too much to be honest. thanks for showing great diagnostic skills and your really good at the pico scope.
Any ideas on code p0017 after replacing timing chain on 2.4L? Car idles great just has the code? Can’t find a solution anywhere on internet or mechanics near me
@@sethking4169 did you replace the sprockets or know 100% know If timing is correct
@@410AutoTech yes sprockets we’re changed and timing was spot on. After a lot of research I found specs for the camshaft and discovered that the rings had slipped an 1/8” thank you for the reply
Love your channel. Ty
Eric,
Excellent diagnosis, explanation, and video - thank you. I like the 'sunday best' look on you (and a bit longer hair) - you look GOOD! Looking forward to a follow up video on the total fix for the ol' chivy.

God bless

nice Diag. looking at those pressure files really taxed my old brain in 4 stroke engine theory of operation.
Acupuncture in the automotive field… Great work Doc!
Getting fancy with the editing! Nice!
Tech2's are such a strong relic for a scanner. Always loved em : )
very informative diagnostic video, thanks for posting. from what I understand, the ecotech has known timing chain problems that wear over time.
Excellent information, I happen to own the same car but white in color. These also seem to have issues with the BCM connectors needing di-electric grease on the C2 connector near the front passenger floorboard. Symptoms of this can cause your brake lights to be illuminated when you are not on the brakes. Also, the brake lights will turn off when you apply the brakes...Also...Can make your thermostat gauge not work as well as the A/C Compressor.
I am having multiple symptoms and this is great .
I saw you with no hat on and I said WHOAAAAAAA who's that guy?! 😄 Just kidding. Eric your hair is really neat to be honest. I don't know anybody who is young like you with an awesome head of white hair like that. People buy platinum dye at the store to do that. :) Wicked.
Nice call Eric... replace the chain, all of the guides, actuators, phasers, and the tensioner... With ~144,000 on the clock just replacing the actuators and leaving the other components with probable wear will just leave the time bomb ticking... 💣 (I'm not sure if you're going to mess with the balance shaft chain and tensioner)... But I like to do that too while I'm there...☝ good stuff Mr. O.....
You look snazzy today Eric Never saw you wear a good sweater to work! Good Job
Wear that white hair proudly Eric O, you've earned it. My hair is all white and my prastor (who is bald) commented to some other church members last week, he would kill for hair like mine. lol He was joking about the killing part of course ;-) Always enjoy watching your excellent videos...keep them coming
Don't let everyone fool ya, Eric. Grey hair is a sign of wisdom (or, in my case, living with all women...but I digress.) I'm not a hat guy so I like the no hat look. I thought I stepped up when I bought a Vantage Pro but am learning that one really needs a 4 channel scope to do this simply. Fantastic video, Eric. Thanks for bringing it to us.
Excellent video as always! Instead of a tool box tour maybe a What's This Tool For? during WUW. Best channel ever.
What an interesting video. I knew modern cars were complex but didn't know the complexity in diagnosing them. I would love to work on cars for a living but the knowledge you have seems like it work take years to get there. Enjoying the videos
30 minute master class
No cap?!? 😁 And hey, the Autel 520 came in yesterday and it is great!! Dropped a thank you for the coupon on Facebook! Perfect DIY tool.
DIY Dave what’s the Autel 520? I have the Autel Elite I like it a lot. I had a Verus edge sold it and bought a pico 4425
@@weldingjunkie This is a handheld OBDII scanner. Actually, the number is 529; I fat-fingered that when I made the original post.
DIY Dave cool I never heard of the Autel 529 I’ll have to look into it.
@@weldingjunkie I may actually do a bit of an "unboxing" and general demo video of it here in the next couple of days on my channel.
Nice video Eric! I've always liked your channel, you take a problem and walk us through step by step in the diagnostic process and then if and when you get the job, take us step by step through the repair. I have to admit you make it look so easy but for me probing the ECM is so scary, cause like you said, if you probe the wrong one or cross the probes with a full 12 volts you just had a bad day. New ECM here we cum. Love watching you do this stuff. I've learned so much, thanks for sharing......
I appreciated the "Little extra fun" with the PICO and the wave forms. I'm learning a lot and look forward to TST as well. The screen shots and PIP were really cool. Sam has a good channel too. :)
Two things. You look great! And I’m taking you up on your sign-off. I bought a used camera, some lighting and mustering a little courage to try my hand at YT videos on my favorite hobby.
Great video Eric. Using the incylinder pressure waveform gives you even more proof of the fault.
Awesome job. Thank you.
Sam from toolhut is a great guy. It was nice to hear the shout out.
Great video. I hope you get the OK to do the timing chain on that 2.4 LE5 as I have an 07 Chevy Cobalt with that same engine. The car just flipped 75k miles and am not yet too concerned about the chain on it. But do plan on doing the chain on it when the engine hits 150k regardless if it needs to be changed or not as those are interference engines. The engine being an interference engine probably why valve timing can't be adjusted when those DTCs pop up because doing so might cause the valves to hit the pistons and now an easy fix just got worse. It's also a 5 speed, so when the clutch needs to be changed, I then plan on to take the engine and trans out and replace the clutch and chain at the same time if the chain hasn't been changed at that point. I take good care of my Cobalt and plan on driving it until the wheels fall off not because of rust, as I live in the south, but because of mileage or was wrecked.
Very informative video. I’ve done 2 of these engines with the same codes and both times it’s been broken timing chain guides. Especially the top one under the valve cover there between the cams.
Great job.my favorite videos are diags like this and whenever big nasty has to come out. 💪👍
Hope you get the job would love to see where this goes
You look different without your lid on.
Eric's hair appearing naked in public? on the Internet?! where everyone can see it?
Oh, the shame.
@Case Knives
He said he was driving by and decided to stop in the shop when he was probably technically on a trip to the store for the wife. lol. Eric, you better have got the wife her wine after this detour to your shop. Us on the TH-cam thank you though for thinking of us as well.
I didn't even recognize him. Who is that guy?
@@kthwkr That's what she said after him pulling that stunt.
alx Mold even old Jeep hats break down...
Eric, there is some strange guy doing videos on your channel with gray hair and no hat! He looks like a worn down Chrysler tech. He did an excellent video on a 2.4 with timing problems though. I learned a lot! Great video.
I can't wait to see the repair video for this one.
Love watching all your videos Eric. My question is how many scan tools do you really have ? My guess is 8 and how did you convince Mrs. O that you need another scan tool. Maybe you need to make a video comparing your scan tool collection. The Autel seems to be the best bang for the buck for the diy’er.
Great diagnosis Dr. O
Good info thanks got one came in. Yesterday gotta diagnosis it in the morning.
Hey bud, im working on a 1.4 2012 cruz and i got rhe p0016 p0017 codes. Hard start then it will throw xode on start up,but when it starts right up,it dont throw it. Sceeams to me crank swnsor but ive replace the crank and both cam sensors. Wont throw while idleing,just on start up. Looked at cam sprocks or where the sensors read, and they are good,chain is tight and cams aee still in time,i can slide the tool in the back of them. I cant make the accuators,accuate with a scanner,because of the codes.. i used a GM crank sensor,so no generic sensors. Ive worked on a few of em,but this one has me stumped.
I realize this was two years ago but dang man put your hat on.
Love these pico videos
