Greetings, It’s always interesting watching a master at his craft, that’s you. The amount of knowledge that you have packed into that noggin of yours is enviable. Folks like you that have a PHD from the school of hard knocks are a valuable thing. Good for you, keep up the good work! John
There is a service bulletin about egr coolers cracking due to air lock . I wonder if that happened, be sure to open bleeder in front of egr cooler when filling. I know some of the older cummins had a engine oil intercooler if its blown it could let oil in coolant. Best of luck Warren you are a man of many talents . I was a Dodge Chyrsler tech for 26 yrs and you blow me away
Don't ever think going the extra step is wrong , doing the job halfass is definitely the wrong , You are very good at what you're doing and nobody can take that away from you !
My hats off to you!!! Anyone who can rip the dag dumb head off, clean all the ports, scrape the gasket surface, put all that stuff back together in a day or 2 is F ing Good!!! My heart sank when you said the head was cracked. That's the kind of luck I have. Then you go on and figure out exactly why things happened the way they did. Great mechanics have to be part detectives to ask why this and why that. I like the way you double check things like the fitting in the back of head. Crawl underneath and verify by seeing the washer is in place. Another Great find with the thread protrusion on the rocker adjusting nut. Why does this one have 6 threads showing and all the others have 2?? Will have to start calling you Mr. Lubrication!!! Head bolts are lubed!! GREAT JOB!!! Make sure to make a part 3!! This is a neat show to watch!!!
Great video Warren.....I have an 06 2500 and it has been a great truck. I love watching the Cummings series with you as a teacher,I've learned so much,Thank you.
You can learn something new every day of your life. The ones you remember are the ones that are important to you. you care about your customers that is what makes you the mechanic/person you are and The reason you get to fix all there equipment from pickups to tractor's.
When I was in Cummins training, the instructor said told us steam pressure will blow the egr cooler when the coolant gets low. I've only seen it once myself. Awesome videos
All vehicles have there different problems and unless you work full time fixing one type of vehicle then your going to be scratching your head at times. You always figure it out though which shows your a top mechanic!!! 👍
I worked with a crusty old guy that said... i only charge 25 an hour to do the work, the other 90 is for knowing what to do.. another graduate of the college of hard knocks... Hope that You and Your family are doing well. Thanks for sharing Warren.
Very bloody easy in hindsight Warren, easy for us to sit here and pick holes in ya methods but we all would have been in the same boat unless we work on these all day long and seen it a hundred times.
Just to let you know Warren, I've seen this same situation. The blown headgasket blew the egr cooler. It takes a lot of pressure to crack the tank on a radiator. You only get that from combustion gas.
Hi mate best wishes from UK thanks for these videos going through a rough patch atm got a bit of mental illness going on comes and goes u know how it can get Love these uploads mechanics is in my blood watched u fixing new service truck from year back last night great watch 🙏🇬🇧
Nice work as usual Warren. Glad it was the cooler and not a cracked head. Nothing says fun like having to tear an engine down for the second time because of unforeseen issues. Been there, done that. Pretty clean truck and engine bay for the year and the miles. I guess that is one advantage of working on California vehicles....
I felt the oh sh!% in your voice....man I panicked and I wasn't even there!!! That's a phone call I would not want to make...head gasket blew...took out the egr and radiator case closed as far as I'm concerned...unreal but this is what keeps this stuff interesting....the highs are high and the lows are dirt....driving home telling your self I'm going get a desk job...got to love it
A great comment on submarine service and your work ethic as a result of that training! As you know few can even imagine what you are talking about when you say a simple mistake can sink the ship. You have the right work ethic for sure! And yes, I have been there and done that. I know what you are talking about.
I always put my valve stem seals on after I slide the valve back in the head using the protective sleeve they provide with the seals. I don't want to damage the seals with the sharp edge of the valves. Amazing that head didn't need any guides or seats....seems like everyone I year town has them beat out of it.★
I think you were spot on with that one, plenty witness marks on the head and block around number 6 there, would of like to have had a look at the gasket too.
This is the 3rd time I've heard of this. You are right on the $. I just watched another channel the other day where they were talking about the same problem. It didn't crack the rad. If you read the forums on the early 6.7 they are prone for popping head gaskets around 150k to 200k miles. I'm putting heads studs in mine just for this exact reason.
Whenever i put the valve collets on the end of the valve i always add a blob of grease so that they don't drop off while releasing the valve compressor
In all my head gasket jobs the fire rings were always compromised. I have not dealt with the modern diesel emissions equipment. I would though always want to change the cooler in any blown head gasket just to be sure I didn't introduce a coming failure. Those coolers cannot stand the heat of losing the cooling system under full load like you described the failure.
Great video, your camera's mic is adjusting for background noise from mthe space heater jet engine thing. As soon as you start speaking it automatically adjusts for your voice but takes a few seconds. hope this helps. Try turning the auto gain function to off and see if that helps
Your a good man Warren for sure, I’m the same way as you man the last thing I ever want to do is screw one of my customers, I’ll second guess the shit out of myself and spin myself in circles to make sure I’m doing the right thing, I can’t sleep at night if I know I didn’t do what I could to make sure I was doing the right thing yanno
The government didn't tell anybody to run an EGR system. The Government set up emission standards for oxides of nitrogen. The manufacturers came up with the ways to meet those specifications and one way was to recirculate exhaust gases.
I don’t think that is splitting hairs Warren. You and I know that the EGR system will be the CHEAPEST way to do the nitrogen reduction. I wouldn’t mind betting that there is a simpler, longer lasting and better way to do this, but the big manufacturers choose the cheap way,to retain market share at a pre arranged market price.
E.G.R blanking plates, with or without a center hole to avoid throwing up codes, very popular mod here in OZ, but illegal, more power down low, slightly higher exhaust temps. Fit a catch can to dry out the intake is the next best thing or do it too.
The sound issue seems to be a noise supression from the camera to avoid background noise coming from the heater. So when you move back and forth the thing goes crazy. Just my 2 cents. Great video!
What's with the Audio? I finally turned on Closed Captioning, the audio was there but low. If you adjusted up, when it came back it'd knock you off your seat.
Your right. The only way you split the rad tank is compression pressure. At full boost with an emissions on diesel you might get 40 lbs. That won't split a side tank.
IMHO, there's nothing worse than fixing a problem and realizing that wasn't the problem, or in this case, there's another on top of the original #FML good video regardless
Great vid as ever Warren, Should the valve on the radiator cap stopped so much pressure building up or did it happen so fast that the damage was done by then ??
Chicken & egg. Did the head gasket prob blow the cooler or did the cooler fail blow the head? Either way it looks like the resulting combined pressure blew the radiator? Good job as usual Warren.
If your using a Go Pro for the footage they have a limiter compressor for the audio so background noise plays a big roll in the sensitivity. Even tho it is a unidirectional microphone the further away you are from the camera the background noise will always take the lead in the recording process. Hope this helps.
Hey....i've been subscribed for a while now,,and STILL subscribed as you're doing something right.Loving the way you tick fella as i'm a spanner man myself.........best wishes from across the pond..
The only EGR design that has worked is 2010 JD 4045T powertech common rail 16 valve engine, i found after 3000 hours the exhaust port was clean and no residues in the EGR valve, I rebuilt the engine due to hole in radiator thus seizing the engine, also i found the EGR cooler leaked due to the overheat as my rebuilt engine with no oil in the sump had water flowing out the sump plug, $1500 New EGR cooler cleaned the water out, engine perfect, if this engine is made in China it is the typical example i see all the time, engines from China do not last.
@@Only-one-life-68 US manufacturers have to reconsider their plan, making the Chinese economy stronger is bad for the rest for the world as they put that money into their military, plenty of other countries around the world who can make quality reliable engines, just feed the Chinese peanuts so they don't grow too big i say,
I appreciate your attention to detail. I worked in a yard over 36 years on surface ships. It was common to hear guys say they built the boats like there kids would have to sail and fight them. You don’t cheat or cut corners if you had to put kids in harms way. We built lots of destroyers and frigates.
the head gasket failed, and the combustion/air bubbles, got into the cooler and since she was under load and high egts the egr cooler tubes got really hot and when the coolant returned to the part the bubble was the pressure and temperature change can be so serve it will crack the cooler, or the top of the cooler was nothing but air and the high egts made it soft and extra pressure popped it. im leaning toward scenairo number 2 but eathor way teh cooler was an efect of the head gasket buddy, your good, when in video one when u said the cooler was wet i knew it failed i fugred u would put a new one on since its high milage and they do coak up over time
Warren, when the audio dies like that, I use the closed caption. It reads a lot of gibberish but with a little decryption I can figure out most of the vocal
Warren, were you a sub sailor ? What years ? I was airdale east coast. In from 10/18/71 to 8/15/75. ADJ-3 rd class petty officer ! What was your rate & where ?
Yes I believe Warren was in the American NAVY,he was telling us about it sometime ago. Hes a one top guy.🤟. He told us how a poor young sailor had passed away and that the sub had to stay out of sight so the poor guy had to go in the food cooler until the sub could surface/return. Sad story
I'm a bit confused. You thought that it was possible that it just a busted EGR cooler causing the issues and didn't need a head gasket? But you reconfirmed your original diagnosis and reasoned the head gasket leak caused the other damage. You didn't want to charge the customer for unnecessarily replacing the head gasket. So if you checked the EGR cooler first and found it was faulty and replaced it, the head gasket leak would have caused the new one to fail and crack the tank again also? Sorry, I'm a bit behind and don't even know what the hell and EGR cooler is exactly even though I get the gist by its name and the plumbing. I'll re watch again maybe I can figure out why exactly you were worried.

Gday Warren Thanks for your service.My brother in law was a submarine specialist main seal fitter traveled all around the world.
I like your careful error analysis and conscientiousness :-)
I think you do good work warren, keep it up

Good job mate, your work ethics and honesty is admirable though rarely seen these days, keep on cranking
no problem with sound, book info. is always easier to find than digging thru the dust in my head. THANKS.

We has the same problems on our tow truck. M2 freightliners It was always the egr cooler. We had the same symptom. Keep up the good work.
good explanation of the torqueing of the the injectors and tubes.
I think you were spot on with that one, plenty witness marks on the head and block around number 6 there, would of like to have had a look at the gasket too.
wish we had a mechanic like you here in new england

master tech warren good job
Just curious, if u put to much oil on the head bolts, will it cause the bolt to hydro lock and give you a false torque?
Your a good man Warren for sure, I’m the same way as you man the last thing I ever want to do is screw one of my customers, I’ll second guess the shit out of myself and spin myself in circles to make sure I’m doing the right thing, I can’t sleep at night if I know I didn’t do what I could to make sure I was doing the right thing yanno

Thanks for the lesson in doag on the cooler.i will use thst in the future on any I work on with that issue
You're right. Headgasket went first then the egr cooler.
What's with the Audio? I finally turned on Closed Captioning, the audio was there but low. If you adjusted up, when it came back it'd knock you off your seat.
@Top Dead Center Grow up.
It's never bad to do the right thing. Keeps us from having to do the same job twice. But with certain makes, you don't ever know.
I was in the navy also. "Be the job big, or be the job small, do the job rite, and get stuck with it all." "A bitching sailor is a happy sailor."
Good catch Warren could have got real expensive real quick !! Well done 👍!.
Your right. The only way you split the rad tank is compression pressure. At full boost with an emissions on diesel you might get 40 lbs. That won't split a side tank.

You did a good job sir 👍🏻
Great vid as ever Warren, Should the valve on the radiator cap stopped so much pressure building up or did it happen so fast that the damage was done by then ??
Doing things the navy way has stood by you Warren. Get things right and it wont come back to bite your ass.
Chicken & egg. Did the head gasket prob blow the cooler or did the cooler fail blow the head? Either way it looks like the resulting combined pressure blew the radiator? Good job as usual Warren.

U must have alot of trust in that vice bud keep up the goord wrk
Great video as always Warren. I got a used egr cooler that I could sell.
I suspect that the gas blower flame thrower noise is overloading the microphone input. It cuts the sound input and occasionally it cuts back in....
I think your 100% correct!!
It must have had more than one issue. It's like layers of an onion. Keep on keeping on partner.
"Attention To Detail" I remember it well.
I have learned the hard way to check those damm egr coolers on morden diesel engines, have been bitten in the butt a couple of times.
No doubt it had a head gasket problem only way I've seen oil in the reservoir...👍👍
Hey....i've been subscribed for a while now,,and STILL subscribed as you're doing something right.Loving the way you tick fella as i'm a spanner man myself.........best wishes from across the pond..
Well the problem got found so you did it right.

Throw a couple of lines on the cooler, put it in a big drum of water and pressurise the coolant side of the cooler. Bubbles will tell the story.
i forgot that fuel line on back of head when i did my head gasket what a mess it made
This is how i remember when working on the Cummins.
15 is to young 36 to old 24 is just right 😁
Phenomenal as usual
I appreciate your attention to detail. I worked in a yard over 36 years on surface ships. It was common to hear guys say they built the boats like there kids would have to sail and fight them.

you are great to watch thanks a 1000 times
Sure seems like it’s very complicated! What I learned was if you are an amateur like me, leave it to the professionals!
Some really good info
Great lesson.
Which is the better engine? Cummins, Ford, or Duramax.
the head gasket failed, and the combustion/air bubbles, got into the cooler and since she was under load and high egts the egr cooler tubes got really hot and when the coolant returned to the part the bubble was the pressure and temperature change can be so serve it will crack the cooler, or the top of the cooler was nothing but air and the high egts made it soft and extra pressure popped it.

Hi,. Was it hard been on a sub when used to the wide open outdoors. I would feel so claustrophobic
Why didn't the radiator cap save the system from over pressurization?
did we check the pvc cooler first
do you think it may have an oil cooler issue also?
Warren, when the audio dies like that, I use the closed caption. It reads a lot of gibberish but with a little decryption I can figure out most of the vocal
The radiator was cracked before any other problems came up.
Love ya, Warren.
hi warren audio has gone very low on the video for some reason keep up the great work stay safe from the U.K
Sorry you are having trouble with your audio really makes it hard to hear always enjoy watching have a good day
Warren, were you a sub sailor ? What years ? I was airdale east coast. In from 10/18/71 to 8/15/75. ADJ-3 rd class petty officer ! What was your rate & where ?
Yes I believe Warren was in the American NAVY,he was telling us about it sometime ago.
Hes a one top guy.🤟.
He told us how a poor young sailor had passed away and that the sub had to stay out of sight so the poor guy had to go in the food cooler until the sub could surface/return.
Sad story
Might check engine oil cooler?
You need a top side creeper for these jobs
Your thinking is dead on ... good work wttr
Warren, where are you? Is all ok with u & family?
is lubing head bolts peculuar to this engine or do you do it for all motors
farmer 72 most will specify if wet or dry
Hi just check oil cooler as well good luck
That pressure and exhaust heat in places it shouldn’t causes havoc for sure
I'm a bit confused. You thought that it was possible that it just a busted EGR cooler causing the issues and didn't need a head gasket?

Those that make the most decisions,make the most mistakes.
You know the best fix for this don't ya?
You OK out there Warren?
Yes, I am fine.
Good video, enjoyed it
Another great Video
great vide well explained as to what was happening. pitty about the audio
I was in a Navistar class was told never run an engine with out coolant in engine it over heat egr cooler and blows them.
