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.

If there is top end rattle noise, it's probably the chain guides, chain and intake cam phaser gear is sloppy or there is an issue with the primary tensioner not getting enough pressure from oil galley. Clog, or bad oil, or front guide rattled and broke. Could be reluctor ring, typically is the intake phaser and front primary guide in these ecotec's.. Which if the front guide breaks, the oil pan and sump need cleaned out, along with oil galleys through entire engine or there will be micro-plastic getting into the hydraulic lash adjusters, phasers and tensioners in return causing slack's and front guide rattle\failure.

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!

The pressure transducer seemed excessive until i watched through the analysis. No wrenches, no bolts, guaranteed diagnosis.. Well Done!!

I’m just over here nerding out on the picoscope analysis 😂🤣 Great video, and diagnosis.

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

You're a diagnostic Guru Eric..... smart man, knows what he's doing and is kind enough to share his wisdom!! Good for you man!

Honesty, integrity and intelligence. The folks in your town are lucky to have you.

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!

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.

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.

Excellent diag. Always good to see you cross-verify your diagnosis. You're definitely teaching lots of folks how to do it correctly.

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.

Great video Eric! Love the pip editing and use of the pico. Great stuff like always bud.

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 really enjoy your videos, very educational and informative. Thank you

Thank you Dr. O. Looking spiffy. Almost thought I was on a wrong channel. Good job brother. Have a blessed and safe week.

very informative diagnostic video, thanks for posting. from what I understand, the ecotech has known timing chain problems that wear over time.

You love your work, and I love watching you do it. I'm glad you're no a dancer.

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

Very thorough diagnosis sir. A bunch of great info as well. Thanks Dr. O!

Acupuncture in the automotive field… Great work Doc!

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

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.

Tech2's are such a strong relic for a scanner. Always loved em : )

It’s great that you enjoy your job.

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......

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.

another great video. thanks from the UK.

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!

Nice diagnosis & great video. Hopefully you get the job!

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 KZread I can always agree with. I won't mention the others. LOL

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.

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. :)

Excellent video as always! Instead of a tool box tour maybe a What's This Tool For? during WUW. Best channel ever.

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.

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 KZreadLand - 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. :)
