xD xD XD the only way to fix those Euro cars, Dan....NO SHIRT REQUIRED hahaha!That educational simulation software is so cool...maybe I will try to get the high score ;)
Please do but your not allowed to use duct tape, and you can do it indoors so you can even play it shirtless in the winter😉 Ha ha, thanks for stopping by!
Love your Video's!💪
Topless, the way to get answers and air out the nipples. lol
hehe Ivan he did a great job being you at the end of this video! Anyway Ivan I ready like your videos too, along Eric-O, Keith.
But, Dan can you speak Russian? :)
@@StarTrekforever3698 me to, they are my teachers, Blessing
As I told you before there is no one who explains better than you, anyone with a little mechanical inclination can save thousands of dollars .... man two thumbs up ......
Thanks! Thats a great comment!👍👍
I am 110% sure Dan new it was a compression issue from the minute he first cranked the engine, what I love about his videos, he walks us through step by step to ensure your average audience is able to follow. Watching your other videos, it is very rare to find a mechanic with such in-depth electrical and electronic experience. very professional and is able to pass the knowledge on in a clear manner. very impressed all the way from Canada.
Legend! Just when I thought he was done with the diagnosis,he goes that extra mile.the man is good!
I would say the Man is God
Great
Who is disliking these videos?? Parts Changers I suspect.
Again very well executed and I never knew about that relative compression tester. I have always thought you had to have a scope for that. where you find these random tools I never heard of before is beyond me!!
Scotty's fans
@@jaspernemesio3816 Scotty can be meh but he doesn't spread false information and I've learned plenty from him. He's just cocky
Hi Dan, thought I would like to tell you the way I was taught to do this diagnosis back in the 80's. Missfire check step 1. Compression test. Step 2 on confirmed low compression pour a little engine oil into the cylinder, carry out compression test again. Results. If an increase in compression it is piston ring or piston related. The oil seals the rings temporarily. If no change it is a valve and nearly always an exhaust valve with a V shaped burnt chunk out of it. It was more common those days because no one was even running on unleaded fuel and I remember the first advert for a car with a cat fitted and we laughed about how were you supposed to find a garage that sold unleaded fuel to put in it.
We are getting old😂😂
I could hear from the first crank it wasn't going to end well for the customer. Great video for breaking down the entire procedure, Dan!
Indeed!😉
I worked in a Subaru shop... I am used to low compression I can hear from 20 paces and two rotaions :D
You are an absolute star Dan. I have watched a couple of your videos and now I’m a subscriber. You are teaching me more in 30 seconds than anybody can in 30 weeks. 👍
Good video for those that don't know. One small thing I think you should add. Tell people never to just drop spark plugs into their holes as they can sometimes hit the side as they fall in and alter the spark gap. I've just found your channel thanks to South Main Auto, and remember if he can do it, you can do it. ;-)
I've been using a magnetic plug socket for 50 years. From the old Porsche VW days. Treasure my old tools.
Great video for diagnosing a misfire for learners. Any experienced mechanic would call compression without testing anything just from the engine cranking sound. The drop test would confirm the low cylinder without any need to swap plugs and coils. The tool looks awesome for those without a scope but remember it is a relative compression test and not an actual compression test.
In the test shown we seen 1 very low and 2 low and 1 high. You will always see a high after the very low cylinder as the crank spins faster on the cylinder with very low comp and then draws more amps on the starter with the next cylinder in firing order that has compression. It is likely that the other 3 cylinders are equal in comp but may or may not be low also.
Good point. I will remember that. Still, this guy is awesome, isn't he?
@@jaspernemesio3816 he is
dan is irreplaceable technician , dan you made me love my job even more every time you share your video , thanks for sharing great topics as usual .
Thats great you enjoy your work, you spend the biggest part of your life working!
I am a motor mechanic in Australia and use your diagnostic to teach our students you should be very proud off your self Well Dan
I have to say that you explain the diagnosis so well. Many times so many details are left out manuals and videos that could really be useful, which you include in your videos. Making a part changing situation into an actual repair. Incredible job and video. Thank you so much for your time and posting.
i can not stop watching your videos my language so weak but you can easily connect the information thank you with all my heart
Ha ha ha😉💪👍
Excellent video!! Great teaching skills, and I knew there must have been an Ivan connection. He uses a Foxelli headlamp which I started using. At 69 years I need light to c. It's rechargeable and I have two. Never leave home without it. And I need you tube handy, so that I have DD with me all the time.
Mine is also rechargeable, your still young Bill😉
Danny boy I have your respect mam I am taking my introduction to engine repair and in class we are using electude and since you said you have helped them make their program Im proud
Love the patient you have and how clear you are when it comes to share knowledge
That's very interesting Dan. I might just have to play around with it. But Ivan will be the high score for sure! Great work showing us and explaining the misfire. The ending was spot on!
Please do and try to beat the rest of us!
Very nice process of elimination! Thanks for the links! Great impersonation!
Thanks Thomas, Exovcds impersonation next time?😉
Came across this channel this week, what a gift from diagnose heaven
Wow!!! What an awesome video, and a great way to explain diagnosis. I'm late to this channel, but I hope there are many more videos to come!!
Thank you for sharing this Dan. Mr. O. recommended watching you. He was right.
Thanks for watching my video's it's appreciated!
Dan your videos are so precise and clear. truly enjoy watching and learning from you. Thanks much for sharing your knowledge and time. The car didn't sound too good on cranking start-up. Am I correct in hearing that? Thanks again for the video. 👍
Yes you could already hear it when it was cranking😉
Every time I watch one of your videos you blow my mind with your diagnostic skills. Thank you
Wow, I'm impressed, I was sure the rings were bad, but you proved me wrong. I used to be a mechanic in the late 60's and early 70's, it was easy back then, points, plugs, condenser, and that was your tuneup. I'm lost under the hood now, but am learning, thanks to men like you who are willing to share with us. Thanks again.
Points🤔........I can't remember when i changed those. But for sure a long time ago😂
Brilliant video as normal Dan 👨🎓
Thanks!😉
Nice Job Dan..Congratulations on making 10K subscribers..keep them coming!
Thanks that's thoughtfull of you!😉
You're a great teacher, many thanks for being so methodical and including explanations.
Dan, just found your channel and I have been binge watching. You are a great teacher and I appreciate all your hard work. Keep the videos coming. Awesome job. Thank you. 👍👍
Thanks for the video. I have been going through diagnose dan withdrawals
Now you have something to watch!🤣🤣
You have given me another reason to seriously consider investing in a storage scope. I'm more in the electronic line where a good scope is almost a no-brainer (I already have an analog scope), but it seems rather obvious that you could measure the same voltage ripple on your 12V battery while cranking, and look for the same regular shape to the ripple. If every 3rd dip is a bit more shallow, you know there is a compression issue.
Thanks for watching and you won't regret getting a scope!
I have over 25 years experience on the automobile industry and I got to say that DiagnoseDan is very good for the experience ones and the new people that want to get into the industry. Thank you god bless you and your family
Thanks for the Knowledge. This is better than wasting all my time going to a boring class. Very detailed and even went and beyond to make his diagnose show us evidence of the problem. Thanks you are a great instructor.
With those relative compression tests, it's worth remembering that a bad reading is always followed by an unusually high one, because of the motor speeding up while it pushes the bad cylinder. So, the 3 good cylinders probably have better balance than it seems on the tester. The sticking valve is the only issue.
Thanks for the comment!
i really have started liking these videos you put together here Diagnose Dan, very educational. This channel by far has been very good to me. You and Chris Fix make it worth it!!!
Following you for the past 4 years. I really appreciate your time giving as all the knowledge and experience by dealing, You are the best, thank you so much, regards from dubai
LMAO !! the PHAD impression was spot on, as a do it yourselfer i can relate to his channel.
Maybe a Scanner Danner, Eric O. or ETCG video in the near future.
Keep up the good work!
Ha ha thanks🤣🤣👍👍
Super Imitation of Ivan...Next get Jeep hat, don't shave for week ,and be Eric O "Welcome back viewers "
Very funny, my favorite Russian, Ivan. Glad to have him in the USA.
Yes, he is amazing
@@Diagnosedan i cant get a legend with the wiring diagram DD why?(on the electude simulator)
This channel has grown a lot in four years and I've learned a lot thanks you diagnose dan.
Step by step efficient diagnostic paths. Dan you are a great teacher. Thanks for all you do!
Cool software! You can hear from the first time you cranked the car that the rc failed. I'm surprised you didn't put a transducer in there. Great work bud 💪 oh man poor Ivan 🤣
I was thinking about the transducer, but i'm getting a new one i'll be doing a video on!😉
DiagnoseDan I just got pico WPS 500 transducer. Love it. Please next time don’t forget DOBRODOŠLI LOL 😁😁😁. Great job cheers 👍👍
@@kyhomegarage3430 ha ha so many languages could do a full video on just the intro if i need to cover them all. But you are very welcome indeed,great to have you here. Yes the pico pressure transducer is great. Getting the latest Gmto model in the beginning of next year, i can't wait!
@@kyhomegarage3430 Zdravo
zeke112964 pozdrav kolega😁
You can hear the compression loss when it was being started
Your right!👍
@@Diagnosedan Thanks for teaching us....love your videos!!! I know you can fix that car in 2 minutes, but you spend 30 minutes for the beginners.
The whole Earth bro.. you are different.. I see Gods glory through your works..
Your way of diagnosis is very reasonable, educative and informative.
Dan, you need to take a vacation/business trip to NYC. I've met Eric O. (who is afraid of flying and has never been on an airplane), Keith , and Ivan and you should hook up with these guys for a couple of days. Keith has so much business he could offload some if it to you and you could pay for your airplane ticket and housing by just diagnosing Keith's overflow cars for a couple of days. The three musketeers plus the Dutch boy storming the cars of NYC. I'm sure that Eric, Ivan and Keith are dying to meet you. Actually, I'm certain of it. You should contact these three guys and come up with a time and place to meet up in New York City. Could get a couple of laugh out loud videos out of this meet up. Love the no shirt Ivan fake video. Damn Russian thinks he's Putin.
Thanks for the Great comment, we all know eachother. Keith is coming this way soon.
I bought the electude simulator and is far from reality. Besides that the sound doesn't work, the fault codes is the simulator are very strange defined, a lean condition on o2 sensor will be like " o2 sensor circuit low voltage ", and so on.
@@JoitaConstantin On my computer the sound Works fine and O2 sensor signal low is the perfect code for a lean mixture. Because the O2 sensor voltage is low when the mixture is lean. It doesn't say mixture lean because there are other reasons that could make the sensor signal low like a short to ground. If you want to learn more about this watch my video on O2 sensors.😊
@@Diagnosedan I know that a low voltage means a lean condition, but I never heard about that code description ( I am not a mechanic, so just based on my few checks on family and friends cars ). Now I am facing another issue: water temp sensor in the simulator is changing it's value from 90 to 100 degrees and back constantly when rpm is above 3000 in 2 seconds. New sensor, wiring, computer changed just because is a simulator and I have nothing to lose, and nothing changed. The initial problem was different, and even that one wasn't fixed. I don't know, but this thing is very tricky. Sorry for bringing this to you channel.
@@JoitaConstantin No problem but believe me the Simulator Works amazing and is designed and tested by the best in the industry.
It is recommended to get the Electude Essentials to get a perfect explanation of all Systems. Only if your interested of course😊
I think that one thumbs down must be from Ivan !!! :-)
Ha ha ha No i don't think so🤣🤣 Must be a unhappy customer with a bad Mazda engine🤣🤣
lol I'm sure there's plenty of them about 😂😂👍🏻
No I gave 10 thumbs up for no shirt lol!!
@@PineHollowAutoDiagnostics 😘
The way of diagnose are more than 100% accuracy and have concrete reason telling customer car problem, very appreciate this learning video!
Dan you are a genius the way you explain the fault and the way you go about it I love your videos can't stop watching just shows you what main dealers are like
At 6 foot 6 I put everything on the lift . lol
I guess that's about 2metres your even taller than me!😉
Dear Dan, no disrespect intended Sir, but did I just see you drop spark plugs into the spark plug well... You are so methodical and explain everything so meticulously, that it shocked me seeing you do that... Knowing that millions of people are watching and learning from you Sir, please show them the correct way to "install" plugs and not just dropping them into the hole. One could easily bend the gap or worse, break off the tip and then have that bounce around the combustion chamber causing all kinds of problems.. We are all in awe of you and am myself an avid viewer and subscriber. So please, emphasize proper working methods such as finger tightening things to get them going first before putting a wrench on it, installing plugs with a rubber pipe or something similar instead of dropping them, torque wrenching with proper torque specs etc etc... please know that no disrespect or ill meaning is intended with this message. You are an excellent teacher and are/will be emulated, so I'm sure you want all your subscribers to be the best of the best, so they fix it right the first time...
Thanks for the feedback, and thanks for watching my video's it's appreciated!👍😊
🙄not true
Hi Engineer Dan:
I am From Baghdad - Iraq.
Thank you for this wonderful channel. You taught me a lot about the correct way of diagnosis.. and this video isvery very nice. Thank you from the bottom of my heart.
Dan ,Ivan is a good guy. He helped a lot of people. Lots of mechanics out there just swap parts and leave the problem. That simulation game only have sketchy circuit diagrams. No info on break out box. No way to locate components .
Starting the thread and tightening those plugs with the battery ratchet made me cringe
Been doing it for years, No problems as long as you know what your doing
at least its not an impact!
3/8 makita impact, 1/4 milwaukee. I do it all day long. Aint no thing!
each time I watch one of your videos I learn more sand more...please continue to make the videos this clear as always.I mean showing exactly where you connect electric probes and stuff.
By far the best mechanic known on earth.
Probably one of the smartest brainiest man on the auto mechanical scene on RUclips 👌
I appreciate the teaching method you use. You are a great instructor. Thank you!
That’s the type of tool review the diyer needs, one that is geared for us to fix our vechiles with tools we can afford and actually work without going to tech schools to show us how to use them! Diagnos Dan did it again, you are in the top 3 of my favorites,thanks
Thank you for the kind words!
This guy man, Diagnose Dan is the best comedian and mechanic ever! I was one of those so-called mechanics that went "yep"!
that impression was so good, you nailed it, great video as always
Thanks Chris👍
Dan you are the best automotive diagnostic channel on youtube.
Humor,fun and knowledge = Dan’s channel. Great work! 👍
Thank you!😉
What is 2d2e code
Wow Dan, always 'on point' with your lectures ...... I'm always time poor, so this is really time well spent , thank you!
Wish I had a workshop like that !!! Happy for you Dan !
Thanks!😊
Hey Dan, i have to 'HAND' it to you on this diagnostic job, 🙂 ,you could have put a big Baloon on the end of the exhaust pipe, but the the workshop item fitted like a 'GLOVE' Lol !! i knew some one who fitted an old worn out 'HOT WATER BOTTLE' on the end of the exhaust and used strong cable tie's, and it went the size of a bouncy castle before it blew up!! Thanks for all the great Video's, will check out the software too, keep doing more please, Bless 😇
Another great video Dan. I really like the way you explain it fully to make a thorough diagnosis.
Many thanks for showing us all these tools and diag ideas! You are a legend Dan!
Excellent demonstration of your diagnosis. Thanks.
Thanks for watching!
I had suspicions when I heard the first crank. Well done Dan! Loved your Ivan impersonation!
Dan you are simply the BEST . Thanks for you time.
Wow😝 Thank you!
Dan you are the man..Thank you so much for helping us learn more.I always come away from watching you with even more knowlege each time.And thank you for the link to the software i will be checking it out.
If you want to learn more you won't regret it!
Hi, I am Mahadev from India. I watching your videos I appreciate your step by step diagnosis to reach the actual root cause. All videos are knowledgeable and helpful. I like very much. Thank you.
You are the best explainer I ever heard. Thx for doing this 🙂
Hi Dan. Thank you for your vidéo and the clarity of your speech. You re doing a great job. Keep doing it.
JP from Malaysia
You are absolutely awesome Dan
I just love the way you do diagnostics. 👍
a friend recommended me your channel i really learned a lot from you thank you so much!👏🏻
Very good and educational video Dan. I liked the way you go the extra step(S) AND remove the valve cover to better explain things visually. Most videos don't even bother😒 YOU THE MAN DAN!!!
wow love that little i-tester so fast you could have had that mazda diagnosed in under 5 minutes thanks dan .
Yes, faster than a battery test!
Hola Dan!!!!
Keep up the good work and thank you for taking the time to train and teach your fellow DIYs....greetings from McAllen, Texas.
Dan your videos are excellent, you give very detailed explanation on the subject matter with nothing left out.
here's my 🖐 High five
The moment I watched your first video I noticed the attention to detail...
High five✋😉
Wow.. without a doubt, the most informative 28m Video on car misfires ever.. Thank you Dan.👍👍
Dan, your videos are fantastic!
Always very insightful, accurate and useful.
Keep up the good work mate!
P.S. I'm from Australia so thank you for doing them in English
Thorough diagnosis, as always :). First time you cranked I heard there was no compression :P. Thank you for showing us your handy tools. Every time you make a new video we learn more and more.
Yes you were able to hear it!💪
wow. now that's how u fix cars. after your video, now i know how to find a miss fire on my jeep. please keep it up !
Thanks💪👍
Thanks for the knowledge you give me every day Dan
Excellent video. I learned to use a chopstick in spark plug hole to find TDC at an Asian auto repair shop in 1988. For carboned up (not burnt) valves on a dodge 5.2 V8 a person can use a cordless drill on valve stem with head on the engine after removing keepers and spring. chuck it tight and move up and down to lap in place. a little more work with OHC mazda which would necessitate cam removal.
Sir, such a great video...you are and could be professional instructor. I'm just getting into cars and information provided here are invaluable. Thank you.
Lots of love for your calmly work
Thank you so much!👍
Dan that was truly hysterical. What a great sense of humor. Great stuff
Thanks!😉
Another great video as always , Keith actually mentioned your name the other day on one of his videos for someone to learn from which is a great compliment, Dan Keith and Eric the most awesome trio on You Tube keep up the good work
Thanks for the comment buddy it's appreciated!
You sir, are an excellent instructor!
Fantastic video. Love the way you deep dive into the issues.
More then just enjoy, Dan! Perfect everything as usual! I have same engine on my Service diagnostic car Ford Focus C-Max, 2006. I use it for ouside work covered a big Russian territory with some diagnostic work. Thank you Dr. Dan!
Good video! Just something to add: to an experienced Tech, you can just listen to the pitch the engine cranking & determine you have low compression on one or more cylinders. Also a vacuum guage will be a much more economical way of determining the condition of the engine. I love buying tools, but alot of times it seems like a great idea, but in reality, there are older proven methods.
Yes! Leakdown tester! Love that tool. Quickest way to confirm your suspisions, and to determine if it's time for a new car or not.
Most of my colleagues hate leakdown tests, but in most cases, it takes less time to do than if you spend a lot of time complaining about it.
My first leakdown test was on an Audi 2.0 TFSI with 50k km on it, and no oil change. It had air leaks from the exhaust valves, intake valves and piston rings.
The customer tried to find someone to blame for his lack of maintenance, so he claimed that we never explained to him how important it is to change the oil.. :P
Exactly!
Dan, been following your videos for some time....This seems to me to be the best so far and they have all been good. Basic diagnostics explained perfectly...and thanks for sharing the software info too! Luckily I have 7 or 8 boxes of rubber gloves...
Ha ha ha 🤣🤣🤣 Thanks!
That's a good diagnostic test I've really learnt a lot from your videos DD. Thanks and keep the good work going
Thanks Dan,wonderful diagnosis again,appreciated.
You'r the man Dan,exceptional work like always
Thank you Dan. Good job. I appreciate your videos. Have a blessed and safe week.
Thank you Billy!👍💪
