Back in the day. We use to call it the plastic bag treatment over the dip stick tube. Had blow by in the engine the back would fill up quickly. Wasn't very high text but it worked for blow by on the 392 engine in the school buses. Good work Mario.
Love the Sherlock 'Ohms' sticker on your tool cart.
One more thing to add I see that you have tons of tools and that is absolutely the way this industry should portray itself but unfortunately there are tons and tons of shops that do not even have half of what you have operating
You make this work look easy and cool 😎
What articulating borescope are you using? The picture quality is fantastic
The teslong td500
Mario, you ROCK/AWESOME information and thought process thanks for sharing.
Oh man another Euro bites the dust lol! How many miles on the Jag?
125k+
@@SuperMarioDiagnostics at least it broke 100k miles... what's the price for a new engine?
@@PineHollowAutoDiagnostics is good to send it to the crusher.jag are crap cars.
@@marlu6373 Silly.
Great video dude, which borescope are you using ? Looks a good tool.
Side note from automotive diag,, man Im loving that intro song ,, Is it an actual song from a band??
Yes the song is called: quasars in the distance
Thank you !
oh man....pico 6......... NOOOOOO!!! great video but you gotta get switched to 7!
How much would that tool run for the ignition analyzer
Around $300.
Where are you getting these leads? You say Jarhead diagnostics?

Question:- Mario How you got The pressure waveforms (The ones in red on pieco) while you connected the first channel of the pieco to ignition coil connecter and other one was battery voltage??
Yes, battery voltage from obd connector using a breakout box
@@SuperMarioDiagnostics So instead of using Pressure transducer You used Battery voltage to monitor compression?
@@carhacks3590 no, instead of using cranking amperage using an amp clamp, i used inverted voltage to do the same thing. It's simply to see how even the compression is across all cylinders by the amount of load the starter places on the battery in order to crank past each cylinder
@@SuperMarioDiagnostics Thanks Mario You are not only awesome tech but U are great teacher as well
It was difficult to understand earlier when I watched your video But now I am cleared
Thanks Again
Love Ur Channel From INDIA 🇮🇳!
probably caused by driving with a misfire with a faulty spark plug for the past year
please details all matrerials used so that we can buy
If the injector is leaking or has failed, scope the rail pressure signal (ac coupled ) and sync it to a fuelinjector signal (voltage or current). You should be able to see each injector opening on the rail pressure signal, a failed injector would stand out.
There is a lot of info in this video, thanks Mario.
That was going to be my next step if the customer had approved it
That test sounds interesting.
Yet another great case study, Mario. I like the use of a pressure transducer on the crankcase to capture a pulsing waveform. Keep up the great work.
First time at your web site. I found you through Ivan's work on that Mercedes. He gave you big props for information as to how to reprogram the ecm, I think. I enjoyed this Mario. Thanks.
Another great video. Could you tell me what boroscope you were using in this video? It's super clear.
can i know what borescope ur using thanks
Hey Mario, awesome diagnostic. FYI these Ecoboost 2L engines (2l GTDI) have a fair amount of LSPI related issues. I myself had this problem where my ringlands cracked and lost all compression on #3. It was an easy diagnostic as it was billowing plumes of smoke out of the tailpipe and through the crankcase.
Loved the video. Where can I get info on that engine? I have a 2015 XF WITH P0016 AND P0017 that points to an actuator.
Great video Mario! I have some of Darrell's cables as well and theyre top notch!
I commend you you're very knowledgeable doing this live is very challenging it's also carries the event of being embarrassed but from the way you're handling yourself You're very confident and competent you know the test that need to be run and for the most part remove any doubt more than once similar situations I start taking a rings off the pistons and bingo part of the land falls down I could sit there all day long with a ring still on it look at it not see a damn thing wrong soon as I pull those rings all hell breaks loose lol keep going you're doing very fine job having 51 years under the belt 35 plus ASE Master tech I see you're doing a wonderful job
Basically 99% if there’s anything to involve the engine that’s need to be rebuild , customer will decline to dive into anything further . Lot of work n no one is going to pay for it.

From Nick Ayivor from London England UK 🇬🇧
Very good diag mario ,thanks for your video.all good for you mario👍👍👍.
You know brother mario ..recently ivan from phad had a challenging Mercedes-Benz and your video came as a guiding light in his repair.great job you do always. Cheers
He just dropped part 5 of that. I see I'm not the only one following both of these guys haha
I discovered Super Mario's channel because of Ivan's mention during his programming of that Mercedes computer.
@@brentv9901 scanner daner ,sma,advance level diagnostic,oz mechanic,phad,and many more other channels are worth watching and to follow as a industrial programmer i work on cars 🚗 for family and friends but i learned alot from all these guys.we should appreciate these guys not for their work efforts but for their honesty as well.
If you didnt notice mario commented on his part 2 and 3 🎃🎊
You must be a Journalist for breaking the news to Super Mario
Great video Thanks! Which Borescope were you using?
Teslong td500
you need a boom for your test leads like the old sun machines had. yeah i'm showing my age !!!
Thanks for sharing Mario. By chance have you watched Ivan at PHDiagnostics. He just had a four part video on a Mercedes AMG computer fail. I know he mentioned you a couple of times praising you for your European knowledge. It’s a good one. Hope you and family had a enjoyable thanksgiving. 👍
Yes he did and he also commented about the Gyro and the Shift lever.
Great video. What bore scope is that. Picture is great. And your scope set up is niiiiice
Thanks, is the teslong td500
Solid diagnostic process, Mario. I learn a lot from your videos, thank you!
Thanks!
Can you show how to do a relative compression test with the scope and explain which wire your connecting and what the purpose of that wire is
Why were you not on 7 my guy 🙄
Hello Mario, nice job as usual. Hope you don't mind a minor comment, the "tail" of the burn line sloping up is not "lean". That is running out of carbon which is a very different thing. While a crude evaluation, the beginning of the burn line is where the mixture determination would be (firing KV aside). A better source of training for ignition would be the late Mac Vandenbrink.
th-cam.com/video/TgFJVL_WsMA/w-d-xo.html
Be careful with some of the old training though, since feed-forward fueling throws the proverbial wrench in some of the dynamic testing procedures. If you watch Mac's presentation, it was before feed-forward fueling. (Feed-back and feed-forward fueling are not the same thing). Later he did modify his approach a bit for newer systems such as COP. His passing was a great loss to the industry.
It is interesting that much of the "new" tools and techniques (primary/secondary ignition) are mostly static and not all that helpful. Much of this is due to the difficult connections with modern systems.
Would like to see how you would isolate between the crankcase and intake. Would you just do what you did here by disconnecting the PCV and checking? Is there a way to isolate them when doing a pulse sensor test? Still learning and your videos have helped me so much. If anything any videos you could link to help show and understand this better?Thanks
Correct
@@SuperMarioDiagnostics I would add that there is a possibility of a head gasket transferring over to another cylinder and leaking to the open intake but that would only be a variable if all cylinders are reading low compression which I had a case on a 4 cyl jeep that was used to haul a trailer which is not designed to do. Conclusion for me was all dead cylinders, leaking down the rings as it may have forced the engine during the hauling which caused damage to compression rings. I cranked mine with injectors disabled to allow oil build up to rings to ensure that wasn't a variable in my test. Then the leak down showed rings were bad.
Great job bro
I didn't know they offered the 2.0 EcoBoost in the longitudinal configuration
I don't do this anymore, retired/disabled, had #3 coil 07 Hyundai entourage go bad, moved it, misfire moved, replaced, month later #5 misfire. heres the weird, if I clear the codes, it's fine for a mile or two, and once codes for all cylinders misfire. I had to replace oil control solenoid a few years ago. Evidently previous owner missed quite a few oil changes, under valve cover is sludge city, I change oil every 2k now in hopes to clean, as no one here does the BG oil system clean that I can find. I may remove the oil solenoid to see if clogged again.
you mentioned testing cylinder wash with a piece of paper, but you stopped explaining after that but how would the test actually look like?
Question, because its a gdi, might it have been leaking with higher pressure compare to the low pressure fuel pump ?
whats name of that ignition analyzer?
Gtc505
Dang Skippy I like the way you set up that card that is nice do you still use the micsig I haven't seen it in any of your videos recently either way love the information
Good work Mr Mario please advise me on more details I have to learn as an apprentice, I feel like most of automotive books do not have this details, I am interested mastering diagnosis and vehicle electronics( from sensor to cpu)
Yo. What boroscope is that??!!
Teslong td500
MARIO YOU ARE IN A VERY ELITE GROUP OF TECHNICIANS,,, EVEN WITH , AS SIMPLE AS A MISFIRE YOU CAN TURN IT INTO A SCIENCE CLASS,,,,,,, WE LOVE IT MORE PLEASE !!!!!!!!!!!!
I Discovered your chanell from Ivan. If he is praising you then you are in top ten teachers.
Great job brother your one of the best keep showing us your tricks.always enjoy thanks.
I think you concluded that this was a bottom end issue but what does that mean on this engine? Is it a hole in the piston or a compression ring gone? What did you quote for?
Been watching your vids for a few years now and i often wonder how hard is it to work around that camera i know it gets easier more you do it but man that musg have been frustrating in the begining i mean i can bearly work with my wife texting me on the phone lol
Good video , love to using impact gun to remove spark plug 😂
Great video ❤ it. What make is that bore scope
Seeing you and your brother is a trip. Yall look alot alike
expensive failure at less than 100k miles
I understand cylinder wash.. but is that the only way cylinder compression can get into the crankcase? I guess a bad head gasket is unlikely as cylinder to oil passages are far apart, but a hole in the head, or broken piston rings etc can also cause this. I'm just wondering if the loss of compression could be the only issue and not a result of something else.
This is true
unfortunately, customer stopped from proceeding
Great Video, those Jags are known to crack pistons.
Brilliant stuff mario well done really enjoy your content and diag approach 👏👏
I know what’s wrong with it,It ain’t got no gas in it
What was the root cause of the failure
another great video
Hey Mario! Is that car battery powering up your entire diag cart?
Yes, i have three car batteries hooked up to an inverter and charger
Great video, Mario!
Great job mario
i would have liked to see plug n coil swapped from 1 to 2. injector may be the problem or not if that plug wasnt firing........
Can only go as far as customer approves. Plus if that plug was not firing, we'd have seen it in the ignition waveform. Instead we saw a burn line that was comparable in duration to the rest of the cylinders
After he confirmed compression didn't return with adding oil there is no reason to swap coils, since with the borescope we saw that none of the valves were stuck open.
Awesome job!! Ótimo trabalho. Ótimo conteúdo. Great information. Do you have a instagram profile?
I don't have Instagram
Mario.can you elaborate on using a piece of paper to test compression? Thanks.
In the same way that the waveform showed a pressure increase in the crankcase during the compression stroke of the suspect cylinder, a soft piece of paper would also blow outward during the compression leak into the crankcase
great diag Mario ,cool video as always
👍🏻👍🏻👍🏻🌷
What is cylinder wash? What it do? Sorry for stupid questions but I just want to learn as much as I can to be better at diagnostic
It's when excessive fuel breaks down the oil film on the cylinder wall that is necessary to maintain compression
@@SuperMarioDiagnostics got it. I understand now. Thank you for reply
what is name of place the bnc cable came from
Jarhead Diagnostics, they have all kinds of great custom stuff!
Thank you ❤
por que no pusiste el pulse sensor en la varilla de aceite?
Eso no siempre funciona, el aceite a veces amortigua la señal
Can you do a video on what and how to even read the lines of a pulse sensor?
A lot of my misfire videos show this!
I’ll look into them.
what brand of borescope did you use. amazing quality.
