My homeboy Larry bought a Kenworth with the 12.7 some years back and after about a year it started blowing steam out the exhaust. Yeah - liner perforation. 15K worth of overhaul later and he’s back on the road. Great video. Just subscribed!
Coolant kills more engines than oil. Great video. Seen it if a JD as well. 7700 hrs and kits looked perfect due to oil changes. No coolant maintenance led to pin holes in the sleeves for a premature rebuild. Fluids are not cheap but a lot cheaper than engine parts. Dump them frequently.
I just disagree with wasting money on changing to ones that test fine as long as everything looks good on the test there is no need to change things out.
Great video, I recently had my truck eating a gallon of coolant a day, but the warning signs were there before that happened. Pay attention to your truck, especially coolant and oil, because stuff going in the wrong place will cause major issues later.
Have one tore down rite now "Detroit Reman" 300k has had 2 head gaskets put on it in a year . Has had repair counterbores installed and #3 #4 leak compression past the linner flange pressurising the jacket all linners are +2 low If this is how reman works Ill just build my own Good video by the way 👌
Excellent video. I recently had Velocity Truck Center in Lexington,KY give me a $9k quote for a $3k repair. Then lie and send fake photos. Unbelievable.
And here lots of people run around trying to find the least-used, lowest mileage engine they can find- when it's probably the worst indicator of condition. Thanks for the info!
Not telling you how to do your job please remind people to change your water filter on the regular and if your Detroit don’t have one by all means add one!!! Great video
I won a trip with my wife to go to Waco and go to magnolia silos. Thought about stopping by there. I have a shop in north Carolina. I thought about doing videos myself but never take the time. I just watch yours, good job guys. Not many people look out for there customers and inform them of issues that could occur. Always good to look out for your customers

Good knowledge Adam , But this comes with pretty much any engine , Like you say you definitely have to keep up on your equipment or you got a bunch of problems
Thanks for your videos! You are one of the best on your profession. Do you have any videos on problems/ issues + pricing; since while is really good to know the possible issues to look for before buy a Semi, would be nice to know the price to fix of the issue that we find. Of course approximated price since I know that price very from shop to shop but as I said Approximated prices. Thanks!
Hey love the video. I have a 94 11.1 L series 60. What coolant do you recommend then to try and combat this corrosion. Also any additives to oil to help clean out that corrosion???
Why would you replace the coolant if everything is testing good and it looks good that in my opinion is an antiquated outdated ideal from the past. Keep an eye on your stuff and as long as it looks good keep using it
Can you please show a video on how to do the stainless steel injector cup removal and installation without removing the cylinder head? I have a 2005 Coluumbia that has a DDEC V with stainless steel cups and one failed. I am very mechanical, inclined, and rebuilt 60 Series, but I have never done cups before. Thanks
You missed the biggest problem into 60 series, flywheel housing leaking oil plus use a good name brand antifreeze made for Diesel engines that is a 50/50 mixture only
thanks for the info but I have a question for you I have a series 60 and I have transmission oil coming out of my starter and I think that the scavenger pump is not working or the torque converter is cracked do you have any suggestions on if it's not that what it mite be also can you tell me exactly where the scavenger pump is
Hey am working on a Cummins M11 330E we are having trouble the engine is losing oil pressure and shuts off we change the oil pressure sensor can it be the oil pump
Yes. There were 14L 60 Series Detroit engines built without EGR prior to 2004 for on highway vehicles. They were 550 horse with 1850 torque. It was the same block as the 12.7 just had a different crank and rod.
I have a 99 mci bus with a d60 and I need to flush and refill the coolant as well as replace the filter. Do you have a video or any info that you can send my way? IE: flush, fil, burp, top off
I just had my engine overhauled 12.7 pre emissions but the shop never told me any recommendations for oil and im about to do my first oil change tomorrow as well as the fan clucth but I think I'm going to have them replace the hub as well while they're in there. I do have some corrosion but it's not as bad as the engine in the video but when I bought the truck a little over a year ago it had almost an inch of grease caked onto the block and I've been scraping it off and cleaning it religiously so can I just scotch brite it and paint it to protect it..? Even my new head already has surface rust forming towards the back im assuming from water coming down off the window. Its it a freightliner classic.. any info would be greatly appreciated.
We recommend repairing any oil or fuel leaks that is falling on the highway. This is a FMCSA violation and will cause safety violation on the carrier’s safety score trigging a safety audit.
Mane I done changed the radiator, thermostat, coolant flush, turbocharger cooler, fan clutch, and it’s still running a lil hot but not anything like before.
I dont understand how external corrosion on the engine or radiator can have anything to do with whats going on internal? Road salt makes everything corrode, copper radiators corrode even faster.. mine was disintegrating and fins were crumbling but inside was like new. Also the inside of engine is not exposed to anything on the outside so they are not even related. It can look like hell on the outside and look new on the inside... mine does. Road salt kills everything on the outside but cant get inside the engine.
Thank you for sharing. I am explaining that the signs of excessive corrosion can indicate low maintenance for owners looking to purchase a used semi truck.
Another good info video, Thank You. So what do you recommend for a flushing chemical? In gas and small diesel engines I've used Lubegard flush. Another product I have used is called Rydlime this was on larger diesel engines.

It's electrolysis it happens when coolant is running through the engine it produces static electricity and it causes cavitation CATs are bad about it to, they make additives you can run in your coolant to help cut down on it but they say this coolant your supposed to run now already has it

Who did the inframe for 15k is it anywhere near Texas
Need an over haul on my engine too know a good place to
Also like the fact you brought up the bullgear! Most mechanics don't speak on that nor bring it up!
It's very important , most of series 60 if you notice a rough or loud noise under load its most likely the bullgear and the bearing

Will you go over the different rebuild kit for the Detroit 12.7? Like the OEM Detroit or interstate McBee, the alliance kit
We alway recommend OEM rebuild kit due to the amount of time it takes to rebuild. It is best not to chance a failure form a aftermarket rebuild kit.
And don't forget Agkits they sell complete overhaul kits also.
Adam, I truly appreciate this info you provided

check for voltage in coolant also. Electrolysis.
i had one with 12 vdc from coolant to negative battery.
eats out liners metal etc.
how u check that ?
@@zaidchalabi1599 Put positive lead of a digital voltmeter set on DC milla volts in coolant and negative on ground battery.
Should be less than 500 mv or electrolysis occurs.
We check marine and gen sets.
Coolant should not become a battery electrolyte .
Thank you for your input. 👍
Cavitation is mainly caused by electrolysis. Make sure both the block and radiator are properly grounded
What happens when the corrosion damage between the liners on top of the deck, can I still repair the engine or it has to go to machine shop? I seen some inserts on other people block but who does the job?
Thank for sharing your experience and time , great work
Actually, you can pull the oil cooler hard line and shove a camera up there and inspect it. I've done that several times for customers.
Thanks for the info. The oil line may be a bit corroded and break when removed. Again thanks for sharing.

But this comes with pretty much any engine , Like you say you definitely have to keep up on your equipment or you got a bunch of problems

Hey love the video. I have a 94 11.1 L series 60.
What coolant do you recommend then to try and combat this corrosion.
Also any additives to oil to help clean out that corrosion???
Most name brand 50/50 premix red extended life coolants are approved.
So, how often to change coolant? Once a year or once a year? ))
Yes we recommend once a year
Why would you replace the coolant if everything is testing good and it looks good that in my opinion is an antiquated outdated ideal from the past. Keep an eye on your stuff and as long as it looks good keep using it
What about changing coolant filters
How often ?
Coolant filters are recommended to change once per year. Usually during coolant interval service . Coolant strip testers are very useful
The coolant filter can become seized once corrosions has built around the housing.
I heard that a coolant filter should be changed every 20k mi like a fuel filter. They're cheap.
Is there a way to tell the difference between the 12.7 and the 14 liter???
So should a s60 use sca or oat coolant?
Best motor built 12.7 60 series.
Good engine but it’s not as powerful as the modern ones
What's your average quote for an out of frame like that?
What’s price ranges to overhaul one?
Can you make a video on the N14 please
That sounds like a good plan
Question for u , I got oil in the coolant and coolant in the oil pan . There is no pressure in the coolant tank ( more then normal )

What's you price on a half engine reparTion?
thanks for the info but I have a question for you I have a series 60 and I have transmission oil coming out of my starter and I think that the scavenger pump is not working or the torque converter is cracked do you have any suggestions on if it's not that what it mite be also can you tell me exactly where the scavenger pump is
Hey am working on a Cummins M11 330E we are having trouble the engine is losing oil pressure and shuts off we change the oil pressure sensor can it be the oil pump
I recommend using a manual pressure gauge to verify low oil pressure readings.
Was there ever a 14 liter made with out egr cooler or emissions before 2003
Yes the army ran a lot of 14 leader Detroit non-EGR
Any 14L prior to 2004 is pre-emissions.
Yes. There were 14L 60 Series Detroit engines built without EGR prior to 2004 for on highway vehicles. They were 550 horse with 1850 torque. It was the same block as the 12.7 just had a different crank and rod.

Why not just change over to Extended life Red coolant?
Great advice. Ensure to check with test strips as well.
