[@stevens862]

Ray as usual you have explained things in a way that was easy to understand. Keep up the great work!

[@not-a-raccoon]

I love how your "super short" videos are longer than everyone else's long format videos. Keep em coming.

[@MonkeyJedi99]

Doesn't Ray know that he is supposed to be so busy that his own vehicle barely runs? Just like the landscaper with a 15" tall lawn and a house painter with peeling siding! - Ah, I kid.

[@Gary_in_NoVA]

Great educational video on diesel fuel systems! You and Eric O. at SMA are my favorite mechanics, but videos like this are why you are #1 .

[@MonkeyJedi99]

That LB7 engine looked only slightly more fun than a trip to LV-426.

[@Toto-is8ci]

Dang, very cool and wow, complicated stuff. I was able to follow, but only because of the really clear, organized and detailed explanation.

[@theforeman1097]

As always, excellent explanation and tutorial! Thanks Ray!!

[@johngregory662]

I did understand balance rates form your other videos …but this explanation does make it clearer. I think many mechanics own cars usually lack in maintenance issues lol. Live confidently and peacefully

[@pauldehayes1898]

TIL.......Never heard of it until you brought it to my attention. Nice educational stand-alone piece, aside from your usual. Awesome Ray!

[@Ham68229]

Clear as mud Ray, actually, thank you for the explanation. Also, don't let us stop you from going on a long tangent, many of us here truly enjoy your videos, keep them coming. Cheers :)

[@imfloridano5448]

I've worked on military diesels in 5 tons, Bradley Fighting Vehicles, HMMWV'S, and others. But I have not grasped wat you are discussing here in this video until you broke it down. We didn't have scan tools to test for the vehicles problems. This lecture really helps me understand the many other functions of the scan tool which really helps with trouble shooting.

[@blanegardner3647]

Finally, another I can watch. If it is over an hour I don't even bother. Losing channels to watch left and right

[@mikeb1837]

Very good explanation Ray. I have an LB7 with 175k That's had the injectors replaced twice. First set were remans done out of town at a dealership. They lasted less than 30,000 miles. Second set I was able to plan ahead and bought "new" Bosch injectors not remans hoping they would last longer. So far so good. Watching you replacing injectors makes me realize why it costs so much to have them done. That's a lot of stuff to remove. Keep up the great videos.

[@33trn]

While waiting for the major upgrade it would be interesting to see what, if any, improvement you get by running various injector cleaners through it. I appreciate the differences might be due to wear rather than dirt but even so.

[@nordicpride9708]

Most modern fuel injectors seem to fail from wear vs debris clogging them up from what I’ve seen. It is possible to get a plugged up one, but a lot more rare these days.

[@golf25radioman]

I"ll admit I have no experience in the diesel/injectors/etc., area. Question related to the above comment. Does the system's filters and their maintenance play a factor in injector longevity? It sounds like a "duh" question, but I was told ages ago, "there is no such thing as a dumb question" - inquiring minds want to know. 🙂

[@paulocarvalho6480]

This is how to explain to non mechanics how parts work and what they're designed for. Simple, concise explanation. When you get to do the work on your truck, please show us everything. Have yourself a great day Ray, Lauren and Dave.

[@facty2150]

We don’t have hurricane time where I live in Canada 🇨🇦, but we often tell time by how big the spring time flood was for a particular year. 😂

[@bulldogshouse9970]

This video is very educational and very well thought out as far as explanation of what they do thank you for sharing this with us certainly do appreciate it

[@patrickgoodwin3085]

Enjoyed the explanation. Get to learn something new each time I watch. Thanks Ray!

[@tomblobasjamesc.mccollum1740]

Nasty Nate along with Sesame Street was one of my kid's most frequently viewed televised broadcasts. Thank you Ray🎉

[@jimmeade2976]

Ray, when you decide to retire from being an auto mechanic, you would be a great shop teacher at a local high school or community college. Thanks for all the great explanations.

[@richardschmidt6619]

You need a laser pointer. Since I don't have any experience with diesel engines, this is an interesting video. Always nice to learn something new.

[@Starchface]

All this talk of lift pumps and fuel coolers and injector replacement has me convinced more than ever that I do not want a diesel in my life. I understand that people who need it, need it-but if you don't, you don't. I am definitely one of the "don'ts". If there is ever a time that changes, I will make sure that taking off the valve covers isn't part of injector replacement. Thanks Ray!

[@jdub976]

I have only ever driven naturally aspirated gas engines my whole life actually it's my preferred way but wanted to say thank you always interested in learning some new things. This was good.

[@orasmiller1273]

I congratulate you for addressing followers questions. That shows you interacting with the audience ❤

[@JamesWolfgang]

Dude! Rocket Man was one of my favorite movies as a kid. Nice!

[@bobby9195]

Good morning Mr Ray hope y'all have a wonderful day and weekend 😅

[@dereks.6783]

Sounds like Ray is coming home from the field trip with a set of Diesel Logic injectors for the DirtyMax. Hey, they'll definitely get an honest, thorough review if they're in your daily driver. Can't wait for the series. Best mechanic channel on You Tube.

[@DocZoidberg549]

Another great channel is Vice Grip Garage.

[@ZGDX_Smiling_]

@RainmanRaysRepairs Fix your ABS light, I saw it lit up. When I had my ABS light lit up, Traction Control was turn off and another light also did light up because ABS light was on. Many vehicles now with the electronic advancement, one sensor can control one hundred items.

[@davidscott234]

To check the injectors for leak back do a fuel rail pressure test its one of tbe special funcrions on the scan tool. And also its spelled out in diagnostic as how to check fuel injectors. A pump only creates flow pressure is a result of a resistance to flow and if you have a bad injector or injectors causing high return rates your fuel rail pressure reading will not get to the 34k max.

[@delantel6689]

As always great explanation in simple terms

[@ohiowrencher8650]

Love how the wife unit announced she was going to be in every video on your last video:) Way to smack the trolls!!!

[@RainmanRaysRepairs]

🤣

[@michaelweiland6751]

I'm not a diesel guy whatsoever, but I just bought my uncles 140k mile 94 Ram Cummins being he bought it new. I feel it's a family piece. After warming it up, no matter what the first acceleration has a misfire and smokes but goes away after 30 seconds. I just assume its the injectors from what I know about diesel, but I like the way you describe how things operate!

[@TomHamilton54]

A GREAT explanation which I a nonmechanic understood and appreciated.

[@jeffally9115]

Thank you ray I am learning so much you u make it so much easier I like to see ford van in low pressure if you get one to work

[@wilcleno1866]

I nominate Rainman Ray for President of the United States. Ray would set this country on the right path!!!!!!

[@beezul]

New injectors? New pumps? New Turbo? I think I smell an Arod collaboration coming up soon! It's just about time for Aaron to take a working trip down to (warmer) Florida and leave the frozen wasteland for a week.

[@Yurindeep]

This has been Rainman's Mechanical Education. Class dismissed! When you do the work on your truck you can put that on your Day Off channel.

[@АлександрШахновский-х5д]

Ray has the skills, dedication to do the job right. I really envy you in a good way! In diesel marine application fuel is heated. Would it be better to have fuel to be warm. When temps drop to 42F and lower the fuel begins to thicken. I had an issue with truck arriving from Spain and fuel got cold in Finland. And it wouldn’t start. And we could not get it out of ferry using its own power - fuel became like sludge. Had to replace fuel filters and add anti paraffin additive. Temps dropped to 30 during night.

[@dirtrider828]

One addition to your explanation that is very important especially on the LB7s is that you need to be looking at the main fuel rate while checking balance rates. If main fuel rate is low then that can point to fuel injectors leaking past ball and seat. Fuel in the oil isvery common on the LB7s or hazing at idle.

[@skysurferuk]

Problems with your injectors? Coincidentally just in time for a certain upcoming visit... ? 🤣 A great explanation on the workings of these painful devices. 👍

[@edogle8163]

Thxs Ray can't wait for the video on your truck.....

[@crasher88]

great video Ray, probably one of the best videos you have made in a very long time. I am always looking for more information on how to diagnose diesel engines. Wish I could get more on theory of operation and trouble shooting procedures on the Duramax, power stroke, and cummings engines.

[@stevenhogan8476]

Always appreciate your in depth explanations of diesel operating characteristics,thanks. Ray

[@garydole9427]

I have read about systems for sleeper trucks to auto start to charge batteries or maintain sleeper temperatures.

[@Soothsayer-rs5nb]

I was working on my wife's car today and I said "poppen zie hood"... you are definitely having an effect on me Ray.

[@Mus.Anonymouse]

Ray is a bit like the cobbler and his kids, always the last to service/maintain his own. 🤣😂

[@bigfootemobileauto9734]

Most excellent video as usual Mr Ray, thanks again that was interesting and good to know!

[@bobbywright2100]

Great mechanic and awesome teacher thanks for taking the time to explain this to people. I understood but some people have now learned something new today and THATS a good day!

[@madhatter2012]

You ought to add an encore to ALL of your videos, Ray. That was hilarious! You all have yourselves a great day!

[@Papieck37]

Super interesting video Ray. And the way you explain the techinal and mechanical aspects of it, makes it a lot easier to comprehend!

[@mattbrown5511]

Ray, your tangents teach many of quite a lot about late model vehicles. I personally don't mind taking those road trips with you.

[@jbell987]

So when you use the truck as a power generation station, we get a new Pope. Cool.

[@alvinhyman6838]

Ray very interesting that you use "the diesel pot cast" clip in this video! He's covered some very interesting and informative topics, one of the best was with Vinny Himes (Leadfoot Diesel) in reference to shops working on modified trucks with the EPA monitoring so closely, but it was explained that if the mods are being done or repaired during whatever work is being done that there is harm, foul or penality for working on those vehicles. It's just recommended that you record and document that's how the vehicle arrived. Great job explaining the idle balance, needed an old musce car idling with a heavy cam to show that even on gas vehicles the idle being rough doesn't mean that the engine doesn't run well. The ole rough choppy sounds all out of wack idle of non computer engines. By the way no such critter as a VIN number; VIN is the abbreviation for Vehicle Identification Number , so saying VIN number is saying , vehicle identification number number!!

[@ralfie8801]

Ray, you can probably live with those as long as you want, my LBZ has 423K on it with the original CP3 and injectors. It still runs fine and will get 17+ MPG at 75 MPH. I would like for you to check the balance rates on mine just to compare to yours for chits and grins. If only I was closer to you than Texas!

[@AgentLokVokun]

"Short video" "Is 22+ mins" Never change Ray

[@angelojonesjones1311]

Thank you for all the information on injection fuel balance.

[@richwoodcock637]

Do the glowplugs too.

[@jonathoncatterson8901]

The 2500 amd 3500 trucks had high idle too atleast some did. Maybe its just cause my truck is canadian. Who knows it kicks on by itself when its cold and usually kicks out once coolant hits 130f ish

[@RainmanRaysRepairs]

They do have the cold weather high idle feature but it’s not enabled to use on demand. I think it can be turned on or off through the gauge cluster menu but it only works below 37*f

[@markmichlewicz5141]

Nicely explained.i learned stuff and things.

[@allanransby7119]

As usual explained so it's understandable. I'm pretty sure that you'll find the parts and upgrade that Silverado bit by bit. Really nice car. Lots of power and space. Keep up the good work and educating videos. The only complain I have: I've been driving my surroundings nuts by adopting your "Click" and "Oh nooooo" - very funny.

[@stevenclaeys6252]

Thank you for another great video. Stay safe out there. Cheers

[@davidhomen4528]

It will be a fun series of videos when you get to them! I'M looking forward to them!

[@brucecampbell3062]

In Canada, most oil field trucks are left idling all the time o ce it get ti -35 to -50*. Sometimes for weeks. Tuff trucks

[@forgetfulme1719]

Parts cannon makes hypotheses too.

[@jamram9924]

The Duramax diesel engines are originally of a Japanese design. GM and Isuzu, a Japanese engine manufacturer went joint venture on this engine. Other than the GM electronics used on these engines, it’s actually a durable engine with a wide variety of applications throughout the years.

[@meghannroberts8143]

Yeah I smell a trip to Jacksonville for injectors coming.

[@Thelastcritic]

The necessary information of C vs K. Yes! Huge frustration for me that people don't know this.

[@ericschwarz9718]

Hay Ray it’s -25 outside today in Montana

[@lokigames5091]

I definitely look forward to fuel upgrades on the the dirtymax

[@silberwolfy]

Well if you're going to do a electric pump a lift pump fuel injectors and a turbo might as well and add a oil bypass filter too

[@harrysetchell4632]

Allways learning and having a good weekend

[@aperson9495]

When the time comes to do your injectors, I'd suggest looking into the metal return line fittings. They tend to be somewhat difficult to get in, and are super easy to break. Personally, I like the return design of the LB7 and L5P... more robust connections.

[@RepoDraghon]

you should install the high idle kit on the flatbed

[@melsjunk2645]

Ray, if the unthinkable ever happened and you had to replace this truck, would you look for another like this, or something different?

[@JamesWilson-ox1kc]

Want to know also

[@FPVForLife]

He once said, that he bought it because its the last year without this emissions garbage under the hood. Which was a smart move. I don't think he would replace it with anything newer.

[@jtjones4727]

Nice thanks for that explanation. I tend to specialize in gasoline powered vehicles, my knowledge of diesels is pretty limited, at least as far as the finer details go.

[@robm3357]

Thanks for this . This was good info.

[@ford6]

A nice and educational vid, thanks Ray

[@MarzNet256]

The injector balance is by done by increasing or decreasing pulse width to the injectors. The data could also be shown in ms not just cubic mm..

[@jthonn]

Thanks Ray

[@steveb6103]

My F550 with the 6.7 has the high idle set at 1,000 rpm. i'm running a hydraulic pump for the air compressor. I don't use mileage for oil charges. I use the hours. As of yesterday, it has 8031 hours and only 120561 miles. The book says to remove the cab to change the injectors.

[@AKChryslertech]

Yup thats true for most repairs on the 6.7. It is actually pretty easy to pull the cab. It is quicker than pulling the engine out. The cab comes off with minimal effort.

[@jimkamradt7243]

Lucy, you esplained a lota things. Said Ricky

[@KAS_Motorsports]

I need to record my truck build when I start it before to much longer. It’ll be fun. Lol

[@SeanBZA]

Do it piecemeal, first with the injector cleaner, which might help, then the extra pump, then the new turbo, and finally the high pressure pump and injectors. Basically from lowest cost to highest cost.

[@bearing_aficionado]

What a cold miserable morning! Winter has finally arrived. Its a cold windy 18°F outside! Hey Ray, now thats cold weather unlike what you Floridians experience!

[@bearing_aficionado]

​@felixgato4392 no shit what do you think I do? Still doesn't mean I still can't bitch about it.

[@ZGDX_Smiling_]

*18:44** (666), The world already did end for me, and this freaking snowstorm and the entire city has fallen down tree branches. Just seeing that 666 makes me want to shovel more snow again and again and forever.*

[@davidrasch3082]

There's a how and a why to all repairs, I think. Both are necessary to move to the next level.

[@3Blades]

Love it! Can't wait to see you upgrade all the parts you listed.

[@kevincurry4735]

Happy Saturday Ray. Rocket Surgery on the DirtyMax in the near future. 🚀👨🏻‍⚕️

[@skynet1.044]

Upgraded injectors,pump and turbo, might as well 😎

[@scottcooper346]

Maybe the company that your going to visit will hook you up with what you need 🤔

[@LzyD2112]

Excellent explanation Ray

[@patrickchavez3848]

I got ahold of a National Geographic magazine from May 1980, there's an advertisement for DIESEL Cadillac cars. I can't even imagine what it took to work on those. I've never heard of those so I doubt they still make them..or do they,?

[@ronfitz2403]

great job

[@realcygnus]

So, if Ray is a lil bit country does that mean wife unit is a lil bit rock n roll ? 🤪Be glad if you're not old enough to get that.

[@bobbg9041]

So was the customer happy? It would be really cool to show someone getting back his or her automobile thats been parked for years broken, that person wile lower on cash had to be really happy he got his truck back fixed.
