Having been a technician for 44 years, I have to say to you thank you for the whole video! Very nicely done! It's refreshing to see someone that knows what they are doing and can be able to explain it to the lay person in a way that is easy to understand.
Great diagnostics, Eric! I'm an electronic engineer for almost 30 years - your approach is very systematic, logical and scientific. You have a great understanding of the mechanical, electrical and software operation of cars and go right to the most time saving diagnostic method. If you ever get tired of wrenching, you would be a great teacher at a tech college. Any college should be happy to have you teaching the art of auto diag and repair. Thank you for sharing your knowledge with the world!
I've said it before. This is my favorite repair channel, why? Eric's a down to earth dude, quick and to the point videos, I don't have to watch at 1.5x speed like some others just to get to the point and I still usually learn a thing or two.
I honestly love how you make reading tech drawings from timing to wiring simple. Much appreciated and I am learning lots. Defo going to keep watching. Best teacher so far found. Awsome mechanic thank you
Exactly what typical old shops don’t understand, gotta KEEP UP WITH THE TIMES. Cars as old as the 2000s have hundreds of modules that control them, you need to have the equipment to work on them amd understand how to use that equipment. Great Diagnostic!
Speaking of timing. ..On many channels I end-up increasing the playback speed, as I often feel they are wasting time. Your approach is better, BANG, here it is, so I don't need to do that. Thanks for the quality, super-concentrated and highly focused content.
Definitely better to replace engine. Great diagnose process. I had assumed first with most nissans. Bad crank or cam sensors. I know it's a pain to do timing replacement on these. Very involved.
Very educational and entertaining content. I'm glad I live in an era where knowledge and experience is easily transferable through youtube videos like this. Keep it up!
Man Eric I really appreciate the videos! Thanks for being so detailed about the hookups on the car Eric! Because what is common sense to you is not to the newbies in the field. You make AWESOME VIDEOS!!
I started watching your channel with the purple Viper fix. Here I think I’m pretty good at fixing cars but you’re next level lol. If you’re ever in Dallas and want to check out a proper early model Viper lmk 👍
Completly professional wow. Great work and terrific explanation and i as a mechanic and constantly learning trying to be a technician appreciate your channels advice😎😎😎
I had this once with a customers 350z. The second I cranked it and it backfired through the intake I new someone's gonna need a new engine . Checking the codes n compression confirmed it for me. 3 dead cylinders n crank/cam codes. Great content bro #mechlife
Impressed with your attention to detail and explaining of where to put the leads and how. I would've loved to find this channel sooner! you'll be seeing some more interaction from me for sure!
Low oil level causes low oil pressure which causes the chain tensioner to fail and therefore causes the chain to skip teeth. the VQ35 and 37 are notorious for this issue. Well done with your diagnostics.
Beast! I would love to have this knowledge. I wouldn't even know where to start. Maybe one day. For now I'm just a backyard mechanic. Keep up the excellent work!
Please give a follow up on this car. Those engines are pretty tough. I would think a chain tensioner failed thus the chain skipped a couple of teeth. Oil level and condition of oil is critical on variable valve engines.
I believe the shop is just going to recommend replacing the engine with a low mileage used one. It’s less labor and less liability for the shop. If they have any trouble with the engine, the salvage yard will exchange it for them.
Great video as always Eric, your vids are better than a great mystery novel for my analytical brain. I haven't been watching YT much lately, I remember you closed up your shop a while back, are you purely mobile diagnostics now?
Pointing out that the camshaft to camshaft correlation might be off because of the VVT system is something not many people would think of. Great video. Don’t forget to like and subscribe so this channel can get bigger!
It's unfortunate the owner didn't know about you in the beginning. Timing chains are supposed to be much more reliable compared to a belt, plus it's sad that just happens to be an interference engine. Great diagnosis btw!
Great information, even for a DIY guy like me without all the expensive equipment. Thanks so much for doing this one! Also, what’s that classic ride in the next bay?!!
@@Dougdea your cam phasers have moved and you should replace them to adjust the timing back to specs, timing cover must be removed to do this. google it.
This is the reason whenever I hear someone say, “My mechanic said…”. I’m not a professional mechanic (work in a completely unrelated field) but as soon as I heard you push the start button I knew it was a timing issue. I’m guessing anyone with a $30 code reader would have gotten a cam/crank correlation code. Why “mechanics” would try batteries, or fuel pumps to fix it amazes me.
bro i had a similar problem with my infinty m35x. except no power for my scenario, long story short it was some sort of fuse i don't remember with one thou. keep it coming brother i love this videos
Another superb diag, Eric! It's pretty pathetic that the "mobile mechanic" (ugh) wasted the customer's money by throwing most likely unnecessary parts at a problem that accomplished nothing for the customer except decrease her bank balance. There's NOBODY better in Texas than you!
I had the same issue with my 2013 Infiniti g37x.i didn’t have to switch the whole engine.they was getting bad readings from the ignition coils.should’ve did a check list and swapped each part that gave them a issue.from experience I did what the lady probably did and that’s not keeping up with my maintenance.if any one has any questions I will be glad to answer how I avoided a engine swap.
So the ignition coils were the problem? I have an Infiniti I'm trying to diagnose for my friend. 2010 g37. It has p0340 code. I changed the spark plugs and it's still missing on 2 3 and 4 cylinders. Vacuum lines are good. I used the torque app to see what the cams were doing and bank 2 is stuck at -128 degrees. I switched the two on the top front around but it still has -128 degrees on bank 2 cam.
If you have maintenance done on time for 2013-and-up VHRs, you're never looking at a swap. 200K miles easy peazy. New spark plugs at 85K, replaced passenger bank valve cover & gasket at 90K, new rad & main hose at 105K. A whole bunch of rotors & pads, oil changes at 4-6K intervals, never to break down and leave me stranded over 6.5 years now. This 2013 G37xS sedan has 116K on the clock, pulls like it's still 2016 and so... it's in for the long haul, as it should. 🍻
Had/have a similar issue w/ my 09 coupe…eventually lost compression and was Suggested that I replaced engine. Ended up doing so and the same Thing happened with the replacement..need to figure out what’s causing the issue upstream
Eric excellent video and troubleshooting. Have heard back from the shop or did the replace the engine? Eric thanks for sharing and stay safe and well Artie 😊
My rule of thumb is, avoid all European cars. Jaguar, Land Rover (I believe both are owned by Tata now), VW, Audi, BMW, etc., especially all the newer, plastic-built crap.
I remember reading somewhere that the 3.5L V6 had timing chain issues but I thought that problem was fixed on the 3.7L My wife's 2013 EX37 bought new only has 39k miles on it and I change the oil twice a year which means every 2 to 3K miles so hopefully it will be a long time before her car has the problem.
Curious if trying to read codes first would tell you that you’d need to check cam/crank correlation and no need for relative compression test? That’s if there were any relevant codes. Great job btw! I’m binging on your videos lately! Hehe
Unfortunately there were no codes present. The battery had been replaced before I got there so it's possible they could've been cleared when they had the battery disconnected. From my experience there usually are no cam/crank correlation codes if the timing is so far off that the engine doesn't run. It seems like the engine needs to run for a certain amount of time before it will set a code.
ERIC, AWESOME approach brother that shows how professional you are I wonder if u scanned the car if there was any correlation code and as always great video to the point thanks for sharing. cheeeeeers
before getting to the end my guess was a relay or timing, people never overlook timing so often its not even funny. im a newbie still learning and compression and timing is one of the things i check often
Very nice and well done man, thank you for sharing you knowledge wirh everyone else. That is how we are suppose to learn, by doing and grrr getting dirty. And people should appreciate what a good mechanic has to go through to earn a buck, not every diagnostic is simple and easy, some do kick your butt!
The chain is a huge pain and is always being talked about. If someone is doing theirs and you are in a group with them ask if you can do both of yalls at the same time. It will save you from this.

South Main Auto is much better.
@@cocainecowboy1717 I like scanner danner more ... he's more about education
Not all mobile mechanics are equal skill and experience! Well done Eric. Greetings from Canada.
They should have call Eric or Ivan and saved lots of money from the parts cannon.
@@stealthg35infiniti94 That's correct or call another Eric from SMA, Paul from ScannerDanner as well)
100% truth.

great diagnosis. as soon as i heard it turn over i heard the sound of death and would have stopped
When 2 channels is all you really need. Nice job my friend

Its always good to see you solve the problem. There ok mechanics and there are good mechanics. You are a very good mechanic.
This was amazing to watch.. Comp test off of starter current.??...??? Mind blown.. Awesome vid. Keep up the great work man. Def got yourself a new sub
Wow! You never cease to amaze and educate! Thank you for sharing, you do great work!
I seriously doubt that shop is capable of replacing timing chains if that's all it needs. Hence the motor swap.
Great video and diagnosis Eric!
Low oil level causes low oil pressure which causes the chain tensioner to fail and therefore causes the chain to skip teeth. the VQ35 and 37 are notorious for this issue. Well done with your diagnostics.
Gallery gasket
I know it’s a year old, but thank for answering a question I was about to ask, I wanted to know what makes the chain jump
Eric we will always wait for you
Thank you!
You know it!
Yoo there's no way dude, this just happened to my G37 yesterday and I'm glad to have found you
Great engine cranking sound effects Eric... LOL... 10/10 for the diagnosis...
Methodically trouble shot and everything skillfully explained. Awesome content!
Beast! I would love to have this knowledge. I wouldn't even know where to start. Maybe one day. For now I'm just a backyard mechanic. Keep up the excellent work!
I watch your videos as a tool. I'm about to start making my techs watch them
Man love watching all your videos, i always pick up diff.things to go about checking a vehicle
Thanks man ! Keep it up the good videos .
Eric I could sit under your teaching for hours, thank you!!!
Great job Eric
Hey Eric great job. your the man for this kind of stuff.
Love ur channel keep it up 👍 🍻

Worries me. No mention in video.
Great work using the scope for relative compression vs pulling the plugs and using a gauge.
Can you make that cranking sound again!!! As an auto electric tech shop owner I have learned alot from you thank you and keep up the great work
Good diagnostic 👍 not too many good mechanic out there ,all they do is parts changes .
It's unfortunate the owner didn't know about you in the beginning.
Timing chains are supposed to be much more reliable compared to a belt, plus it's sad that just happens to be an interference engine.
Great diagnosis btw!
Based on the RC test it pretty much proves the timing fault. Good video Eric.
That was clear and straight forward explanation. Gotta get me one of those labscope thanks!!!
killer job on explaining what you were doing as you went along, very easy to follow and I learn a nice chunk. Thank you for sharing.
My first guess when I heard you crank that engine was "timing is F-ed Up". Keep these great vids coming, sir!
Great information, even for a DIY guy like me without all the expensive equipment. Thanks so much for doing this one! Also, what’s that classic ride in the next bay?!!
Great video I really enjoyed it 👍
Thanks for watching!
Good job,I thought timing chain right when you first started it.
I'm glad I ran into this channel. Very informative
Unplug crank position sensor, if the engine starts, cam phasers have moved, very common problem.
What do I do if this happens?
Please I need help, I unplugged crank sensor and it starts but with it plugged in it does nkt
@@Dougdea your cam phasers have moved and you should replace them to adjust the timing back to specs, timing cover must be removed to do this.

You’re a real Master Mechanic! Well done!
Love how your quick an straight forward Great job

THANK FOR A COMPLETE DIAGNOSIS AS ALWAYS
Wow pretty rare for the VQ37HR engine. did you check the cam sprocket?
Very good point, don't think he did lol
I had the same issue with my 2013 Infiniti g37x.i didn’t have to switch the whole engine.they was getting bad readings from the ignition coils.should’ve did a check list and swapped each part that gave them a issue.from experience I did what the lady probably did and that’s not keeping up with my maintenance.if any one has any questions I will be glad to answer how I avoided a engine swap.
I have a a 2009 g37 coupe at what mileage did yours start?
So the ignition coils were the problem? I have an Infiniti I'm trying to diagnose for my friend. 2010 g37. It has p0340 code. I changed the spark plugs and it's still missing on 2 3 and 4 cylinders.

You’re a bad man with the skills you have.
Would like to see a video advising us what make of car give or gave you to most trouble motor wise and electronic wise.
My rule of thumb is, avoid all European cars. Jaguar, Land Rover (I believe both are owned by Tata now), VW, Audi, BMW, etc., especially all the newer, plastic-built crap.
Problems motor wise, I would say Dodge Chrysler. Problems electronic wise I would say Bmw or Mercedes. Thanks for watching!

Im so glad I subscribed. I enjoy watching someone who knows exactly what to look for and how to explain it.
Great diagnosis but I can't believe they're just jumping straight to replacing the engine
Good video. Your a smart man. Right to the point. It’s appreciated
Very well done sir!. Spot on. Probably ran low on oil. Very common on the vq .
Short, sweet, and informative. Awesome video sir

LOL But we have a computer that will tell us what's wrong so figuring it out is easy. (I'd like to smack those kinds of people)
Keep going bro. Great evaluation. Plus the video editing are getting better.
Damn i was hoping you fixed it...love your videos bro..eres una verg.....
Spot on. The sound was very bad from the beginning. Nice work! Very sad other shops didn’t pick up on this.
