"hot rod bullshit" bernie, never change. please just keep bein you. im 32 and when i first got into this business as a technician long ago, my mentor talked and acted just like you. i enjoy learning from you
You had me at hot rod bullshit 😂 Really nice and through diagnostic work as usual. I love this kind of stuff! Ray is the man with his never ending library of known goods.
I would love to see on this case study, where the injection timing for injector cyl 1 (bank1) and cyl 2 (bank2) is compared to the in-cylinder pressure waveform for both banks. First with CAM sensor plugged and then with cam sensor unplugged. This would be very hard to diagnose without known good waveform for the crank-cam😎Thank you once again Mr. Thompson 👍
We got to take in all the knowledge Mr Bernie shares. He is a beast at what he do. And Mr. Ray, thank you daily. You have helped me many times over and I wanna say Thanks again from all of us.
I know that the issue you’re concerned with isn’t due to the aftermarket intakes, but I’ve had to tell many customers that the only way I can make their car run correctly and/or turn off the check engine light is to remove their aftermarket garbage and replace it with the OEM stuff. They generally don’t like that lol. I’ve had multiple Nissans come in with a no-start due to cam timing, but the one that sticks out in my head is an Infiniti G37. It had just gotten an oil change at a lube shop that always referred business to us, then the same day, it wouldn’t start. It had a code set for cam/crank correlation on one bank. I started it (the same way you did) and did a compression waveform. The compression waveform showed the cam timing was accurate, but the cam/crank waveforms showed it was off. I pulled it apart, stared at the thing for a while and didn’t see an issue, the mechanical timing marks were correct. I knew from my waveforms that the issue had to be with the cam sprocket (where the trigger wheel was at), so I had the advisor order one (it was in stock, that’s a hint). Once I had the two side by side, I could see that the cam trigger wheel had shifted. It’s just pressed on. Not sure how or why it shifted, but it was. Told the customer it needed a cam sprocket, but recommended a full chain and tensioner replacement too (which they did). After the repair, the cam/crank waveform was perfect. I have no idea how someone without a scope and the knowledge to use it properly would have ever found it. EDIT: I was still early in the video when I posted that. Crazy that this car had the exact same problem as the one I worked on.
Hey Bernie, I was fighting with my 370z and without a scope I had no idea this could be an issue. I most definitely will be purchasing one and figuring out the ropes. I found your video 2:30 two mornings ago after the car sat 2 years with no start, last night the car finally ran and it ran great. Thanks for everything!
Hey Bernie, just repaired an Elgrand with VQ35DE - had the EXACT SAME issue as you did here, even though the design of the pulse wheels is different on the Elgrand, still just a friction fit that must have got knocked while doing a rebuild and changing the chain. Car wouldn’t run with bank 1 sensor plugged in, even plugging in with it running would kill it. No codes. Did the whole diagnostic process with a scope and looking for reference traces found your video. Couldn’t believe it was the same issue, wish we found it earlier! Thank you!
GREAT VIDEO! I know dealer technicians that struggle with this mainly due to lack of scope use. The target wheel is pressed on. These engines tend to burn oil, so when the oil gets low, the phasers rattle, and slowly move over time. This 3.7 is very popular on the Infiniti side, and this problem is common. Would that possibly be Ray Ray from Autonerdz, that provided the known good wave? If so Harley Mike says hello 👋.
@@spirokattan3655 With this car its no telling, maybe some sort of aftermarket "tune" for the "hot rod bullshit" has affected its factory programming, and code set ability.
I bought a 2005 350z and see those two small wires on the front cover, the bolt was the wrong size and not holding it down so the car would not fire up. Once I found the issue I swapped the correct size bolt and the car fired up and ran with no further problems. The sensors are so important on this car.
2008? Odd, because the 370 wasn't made production until 2009. I should know, I own one. Also another known issue with these on a no start no dtc sitch is the steering wheel lock failure, very common and can be remedied by simply removing a 10 amp fuse near the battery compartment.
Excellent diagnosis Bernie! Really well explain! A lot to learn about this problem! maybe this ECM has been modified in this hot rod and that's the reason no dtc's were triggered. I was wandering if we can see the CA of the intake at idle and we have a guide to follow if we don't have dtc's. Thank you Bernie! We're always waiting for your videos!
Just now seeing this. Bernie is tha man. He know hot rod bullshit when he sees it. Never heard anything but problems with that stuff. Thanks again Bernie for another awesome video!!
I take 5 minutes to diagnose any Nissan when they crank but no start I unplug the cam sensors and the ECU goes to its base setting and will use only the crank sensor to turn on. Will ignore the cam sensor if it's off position. It will turn on and run but then most likely idle rough but it will turn on if it's only a couple teeth off. I learned this trick with a Nissan quest v6 would not turn on and would not set any codes the previous shop before me said it was theft system or bad ECU . Turns out the guides where worn and timing jumped 2 teeth Ecu won't let it turn on when detects timing is not right
Amazing class!! Just want to clarify the angle of error you mentioned. The crank sprocket has 26 teeth and the intake cam has 52 teeth.Counted the teeth on the video. To see that error of around 15 degrees off would indicate a 360/52=13.8 deg =1 tooth on the cam. But if you had a enhanced scanner connected to the car and had that pid available then you would see a +- 6.8 deg error on the crank cam relation on that right bank?Or the same 15 deg? I just got confused when you plotted the 720 deg on 1 cam cycle and still found the 15 value. If you dont know how many teeth are in the cam or crank sprockets would be hard to call on the amount of teeth off right? And since you dont have a single notch on the crank pattern i dont know how the pcm knows when is the TDC on this car. Maybe a combination of everything?Thats why it wont start if 1 pattern is off?But it runs in the absence of 1 cam signal? Very interesting video.I just cant believe how much im learning with you Mr. Thompson.Thanks a lot.
Hey there mr Thompson, I really like how give it the umpire philosophy.. call it as you see it.. "hotrod bullshit"... I like all the deep diagnostics.. step by step data driven and Not.. the internet said to replace... That's guessing and guessing will cost ya..
Common issue on the vq37 nissan engine. The reluctor wheel slips everytime on the phaser. Saw 2 engines so far with this issue. And yes very hard to see it even comparing the good and bad phaser on the bench.

This is an amazing video. I actually have the same kind of issue going on at my shop as we speakkkkkk😮
Escope is the best. Love it. Thanks Bernie for awesome information.
Excellent work Bernie, thank you for sharing with us. Ray's library is extensive. Always sharing.
Where can I find “Ray’s” library?
Now that's a good old fashioned Bernie Thompson diagnosis 👍. Thanks for comparing the two parts at the end.

I watched 4-5 of your videos. Scope+scanner is so beautiful.
love the escan.... proud to own one
Great job Bernie Iove watching your videos and learning I work on cars myself I'm surprised it didn't throw up timing codes or phaser codes
Thanks to Bernie and thanks to Ray as well!. Yet strange no correlation code had been flagged.
Perfect diagnose… Thank you so much for sharing and teaching.. I Got the Escan, scope and gas analyser will be added soon.
Very detailed video thanks for taking the time to teach us.

I dont mind batting Clean up lol! Always great to watch Bernie teach!!
My favorite part of this whole video is Bernie saying "hot rod bullshit". Exactly what we all say when we see a modded car with drivability issues!
I hope the owner sees this video so he can hear you say "hot rod bullshit"
Doesn't actually help him any. Just makes it look nicer when the hood is open.
@@tombeam I fully agree and the owner deserves to know that.
Awesome work Bernie, very informative!
That was a great diagnostic. I love it .i learn a lot from you.

"Ray somehow has them all" 😂😂😂 so true
Tremendous coaching . Thanks mate !
Amazing diag as always ATS.
Read alot of your articles in motor magazine
Thanks for sharing Bernie.
Thanks a lot sir for the knowledge
Nice explanation Bernie, thanks for share this.
How does the target wheel position change on a CAM? The CAM targets are usually keyed, or mechanically indexed to the CAM. How exactly can it slip?
Being waiting on a new video
Thank you Bernie
I need to learn how to use a,scope properly!
Common issue on the vq37 nissan engine. The reluctor wheel slips everytime on the phaser. Saw 2 engines so far with this issue. And yes very hard to see it even comparing the good and bad phaser on the bench.
Amazing as always. Does Ray Yergeau have a site.
Hola Bernie una pregunta el eSCAN ELITE ME SERVIRA PARA EL PARQUE AUTOMOTRIZ EN MEXICO Y SI LO COMPRO ME LO MANDAN A MEXICO
Amazing video as always
Great video
You could ask for better but
You would never get it
🇺🇲👍
Thanks Ray
Hi sir very interested and educational videos.
So was the bad phaser an original equipment part that wore out? Was it an aftermarket new part that was built wrong?
Amazing work 👏
good diagnostic tks
The main problem is that the target wheel CAN move. It should be permanently affixed, welded, keyed, something, to where this cannot possibly happen.
Outstanding!
Great video Bernie this probably the first time I ever heard Bernie curse aftermarket b******* 😂
I wish to know how to read scope or interpret scope, I have been trying hard to learn it but am not getting it. It’s really complex to learn
That was really awesome
bernie i want your scope is there any discounts before i buy ...
...except this time "hot rod BS" wasn't the problem! Usually it is the installer/end user.
Ah so all that hot rod crap broke the car! Got it! Thanks!
That’s why I drive 70s, 80s and 90s cars. I don’t have to worry about bs like that… They don’t make cars like they used to. Sad
*insert Catchy 80s music*
When there's something weird beneath your hood...
who you gonna call????
Scope Masters!!!!
✋️ teacher teacher, hahaha, why do you have any intake vacuum pull just cranking? I haven't seen that on domestic cars so far.
Fine job!!!
You definitely need a better mic so that when you're trying to talk over the Nissan trumpets we can actually hear you
I've ran into this issue on Mercedes 276 twice
👍🏻👍🏻👍🏻
Perfect...!!! 👌
What's most impressive to me is that you can do all this in a long sleeve dress shirt.
