I BLEW UP a 12v Cummins, and it runs better now. Whoopsies!

What should I do with this!?
I've had so many requests to blow up an engine on this channel and as I'm excited to announce that it finally accidentally happened.
I obtained this 1995 Ottawa Model 30 from a local plant when it was diagnosed with severe mechanical problems. I don't know what I'm doing anymore.
I own and run a full service auto salvage business and I decided we can tackle this unit. At first, the plan was to flip it to a salvage operation that specializes in medium or heavy duty applications. Obviously you all know who I am, I have to test EVERYTHING so I can sell it with no surprises...well...
I decided to see how it drove and things went wrong pretty quick. The good thing is that it still runs which leaves the question... what's next?
Obviously it has 5 happy cylinders but I'm not sure how a proper torture test should go. Please, let me know what you think I should do with this as I want this to be fun and exciting! Something one of these trucks likely have never been.
I know this is much different than my normal type of video but you know as they say... when at Importapart, Do as Eric would do!
I hope you enjoyed this video! As always I love all of the comments, feedback and even the criticism.
Catch you on the next one!

The fact that it ran for several minutes without oil, threw a rod, put a fist sized hole in the block, and even sheared an entire lobe off the cam, and ran SMOOTHER than before says way more about the reliability of the 12v than the fact that I've never seen one blown up. Cant wait to see it's the carnage in the teardown

[@J.R.in_WV]

They most definitely do have catastrophic failures, at stock power levels like this truck where they’re set at 180hp they’ll last a LONG time but with all the stop/starts and idle hours a yard spotter sees they’ll go through 3 or 4 BT5.9’s in their life.

⁠@@J.R.in_WV Oh, yes, they will indeed! The 12v I blew up went in pretty much the exact same way. It was also in a “yard goat” I told my supervisor it was going to go, and his reply was; “Good! That thing needs a new motor!” It’s hard to justify taking such a valuable and expensive piece of equipment out of action for two days for engine maintenance, but engine FAILURE is a whole different ballgame.

They gave you that for free, the chassis alone is worth about $10,000 used. They just didn't want to take this time to sell it. Yard trucks are extremely expensive brand new, and really a good value used, the problem is that shipping them long distances usually is way more. I bet you could part that out for quite a hefty profit. The double reduction planetary gear set in the rear end is worth about $3,000 on its own.

Good news! The oil pressure gauge IS working. I knew as soon as you started it; dead cylinder. 5.9 12 valves absolutely blow up. A lot. And it's most likely a heater grid being a '95, not glow plugs. The buzzer was the low air pressure alarm - if it's got the Cummins/Wabco compressor, save it. It's on the driver side, mounted to the side of the block, bolted to the timing cover. It's gear driven. Last I looked, cores were over $700. Cores! Better news! Kalmar Ottawa says this truck should have an Allison transmission AND Meritor axles, both of which are BIG bucks. If it's an Allison with PTO, that is pure cash money. Sometimes from GM truck and SUV owners with the Duramax! So yeah! Blow up the 12 valve! Destroy the body! Perform strange science experiments in the interior!

Us truckers call that vehicle a "Yard Dog". It is used to move trailers around in a yard, to a dock and to park. Sometimes to a door where a truck is hard to access. That yellow button is the air brake release and the red knob is for when an air line is attached to the towed trailer and to release it's airbrake.

[@thebigeasy2005]

I knew a guy who worked at Chryslers back around the time Lee Iacocca came over to Chrysler, and he worked at the Engine plant over on Mount Elliot in Detroit. He was an engineer, and they used to talk about “validating” the slant 6, which was pretty much abusing it until it failed, causing different failure modes, running them for hours and hours on end, ect. He once told me about how they drained the water, ran it and couldn’t get it to blow up, then drained the oil and had a hard time getting it to blow up! I guess what I’m getting at is two fold, “validate” what’s left of this engine and two, how bout an old 225 slant 6? I’m sure they aren’t as easy to find as they were fifteen years ago or so, but they put them in a ton of rides. Would love to see a slant 6 torn down, possibly with some carnage!

The wait to start is a light on the dash when you turn the key on . The buzzer is probably low oil psi or low air pressure. The cab jacks up/ tilts forward for engine removal

[@willgallatin2802]

My Mack has the same buzzer. It is a low air warning. Once air pressure reaches 75 PSI it stops. Many of the old Macks do not have glow plugs. Just hold throttle to the floor and crank for 10 seconds. Some Cummins are the same.

I've worn out three of those and worked on them also . There are no glow plugs in that engine . It's the same engine that was installed in to the earlier dodge pickups ( as well many other vehicles and as a stationary power supply - pumps ) . It would have a heater grid in the intake ...

[@ouch1011]

The horrible grinding/squealing noises you were hearing was the metal of the bearings grinding away on all the metal rotating bits. Engines tend to squeal before they start knocking or eject parts. I’m guessing there was no oil in that engine at all, and based off the fact that you didn’t pull the dipstick before starting, I’m guessing you knew that.

Well Eric, congratulations on being the first person to blow up a stock 12 valve. Totally possible when looking for thousands of horsepower, but STOCK?

[@willkerfoot2127]

You should try to fix the holes in the block and fill it with oil and see how long it will last. Just weld or bolt some sheet metal over the hole and silicone the gaps. Even if oil is added, with those big inspection ports the oil will escape and seize the other con rods. Maybe cap off the fuel line to that rear cylinder so it can’t fill the crankcase with fuel.

[@58nunzi]

I like that idea.

[@averyalexander2303]

Not long at all. It's not going to have any oil pressure with a thrown rod, almost all the oil will take the path of least resistance and shoot out the oil holes in the crankshaft instead of going to the bearings. If the oil holes in that crank journal were somehow plugged off, it might possibly have a chance of lasting a little longer as long as there aren't other huge internal oil leaks from the broken camshaft, which there likely are.

[@mfree80286]

@@averyalexander2303 Cut a strap of rubber from something, wrap the journal with it, cinch down tight with wide worm clamps. And then go ahead and pinch off the #5 and #6 injector lines so you don't dilute what oil's left. It's now a 4 cylinder, since that cam broke on 5, 6 is just dead pumping. May as well pin the valves open a little with some shims and cut some of the resistance.

[@averyalexander2303]

[@jtjones4727]

I see why they call them yard dogs now, that thing has an impressive turn radius. Would be good for moving trailers and other things around tight areas.

[@91CavGT5]

A couple of very small adjustments on the injection pump will end up with a severely over fueled motor resulting in a runaway diesel(the engine won’t be able to be stopped unless you stop the air supply, or it REALLY grenades). So my vote is to do just that and REALLY see what a blown up 12 valve is like!!!

[@GMbowtie350]

A runaway happens when the motor starts feeding off its own oil. Usually when the turbo goes bad and starts putting oil through the intake side. An injector pump on these motors can’t cause a runaway. What shuts a 12V off is a solenoid that cuts fuel when the key is turned off. There’s no way a modified P pump would cause a classic runaway where you can’t cut it off with the key.

[@91CavGT5]

@@GMbowtie350 I did not see a P pump on this one. I know it is a 1995 model, and in the pickup trucks of that year came with a P pump. If it has a rotary pump like is used on the 89-93 pickup trucks then the injection pump can be modified to cause a runaway. On modern electronic injected trucks, you are correct in that a runaway is caused by oil consumption. On older mechanical injected trucks it is most definitely possible to have a runaway condition due to an improperly adjusted injection pump.

[@GMbowtie350]

@@91CavGT5You’ll never get that kind of fuel adjustment out of a VE pump. You can adjust the low smoke screw a little bit but that was about it. They were horrible for tuning and made no power. That’s the whole reason people junk those for the P pump. And even still a VE pump still has a shut off solenoid. Even if you could get it to run away you could still cut the key off and kill the fuel. There has to be a shut off on any pre common rail injection pump otherwise how would you kill the motor? They’re all cam driven.

[@91CavGT5]

@@GMbowtie350 oh yes you can!! Go do a quick KZbin search for 1stgen Cummins runaway.

[@GMbowtie350]

@@91CavGT5Those are hot rod pumps with a good couple of grand in them, if not more. That’s nowhere near anything we’re talking about. Head work on the pump, cam gear, everything. That’s a lot more than “just a few very small adjustments”. Plus the shut off solenoid would’ve had to be dicked with for it not to cut off with the key. On a stock pump it more than likely couldn’t happen. Plus that’s not really a runaway. That’s more or less the pump hanging up from the oversized springs and shit. Can you technically call it a runaway? You could but a classic runaway is when it feeds off of a fuel source other than diesel. When someone says “runaway” in a diesel they generally think of running on its own oil.

[@Redleg122]

I have operated a spotter for a number of years. I would love nothing more than to see you tear that bad boy down. For future reference, if you want to get going make sure that you push in the yellow air brake. That will get the truck going. If you need to raise the cab there is a cable that you have to pull that is connected to the switch. Usually it is red or clear. You have to pull that cable to release the cab tilt lock. And then you can raise the cab.

[@treotraveler]

Eric, that truck has an automatic trans with the shift leaver on your right. The long leaver next to the shift leaver raises and lowers the fifth wheel.

Reminds me of the time when I was in the Air Force working at the Fort Dix Warfare Center Satellite Maintenance Shop. We maintained our Air Force tactical fleet assigned to Warfare Center for tactical field training. An old M35 (with the multifuel engine) was driven to our shop for no oil pressure. Somehow the oil drain plug was missing, and they drove it out to the field and back (2 hour round trip, not including how long they were out there). At some point they were contacted by the Browns Mills, NJ PD to inform us that one of the trucks in the convoy had left an oil slick on the way out to the training site. It was pretty noisy when they pulled into the yard. It was very obvious the bearings were done. We decided to do a test to see how long it would run before it locked up. FOUR HOURS later it finally seized. It was impressive how it continued to run even at the lowest RPM we've ever seen. They don't make engines like that anymore. Those things can run on just about anything that is combustible. The Army has a surplus of those trucks, so getting an engine was very easy. Had it swapped and running again in four days! We tore down the engine and was amazed at the carnage. The entire crank lost about half of the thickness of the mating surfaces; the rods were almost worn all the way through. It actually didn't seize; it just couldn't maintain compression after the pistons wollard out the cylinders! The rings and sides of the pistons were shaved down quite a bit. The cylinders showed a lot of spider cracking where they had been worn down by the pistons. The amount of unburned fuel and metal in the oil pan was impressive. We had put a plug in the pan and when we drained it, it equaled the full capacity of the oil pan! We decided to make a display of the disassembled engine with pics and videos of the entire ordeal. Not sure if it is still on display, but it was supposed to be maintained as a historical artifact that attests to the engineering of the good ol' multi-fuel engine! It should be on display at the Warfare Center for Fort Dix, NJ.

Love the sarcastic remarks. That i have to say keeps me watching. Keep up the great content. I built motors for normal and race cars for awhile. I have seen some great things.

[@slwsnowman4038]

I don't know all the questions...but all the answers are content. And for the future, connecting rod caps that were just yeeted out of the engine will be a tad warm.

[@DeerKoden]

"sparsely equipped". Loved that.

[@Meowface.]

“What is that sound? Let me give it some gas” Ugh man.. you had me yelling at the screen 😂

[@mikecumbo7531]

My dad used to use one of these at the trucking company he worked at. They would move trailers to and from the loading docks, then hook tractors up, so other drivers would take loads out.

[@efrainranea8972]

this video proves why the 12 valve is the best engine ever made. marvelous

[@joshuagibson2520]

You misspelled 300 Ford inline 6. And I'm a Chevy guy saying that.

[@xinx-fn8973]

Deletes a cylinder and runs better 😂

[@csutakgergo5279]

Maybe in murica 😅😅

[@TheSleepyMechanic0524]

300 6 gets it all day. As a Cummins dude.

[@GMbowtie350]

@@TheSleepyMechanic0524300 is a damn good motor don’t get me wrong but I’ve seen a lot more dead 300s than 12Vs. You can get all that reliability AND be able to pull 15K lbs with a 12V. A 300, not so much. If you attempted to put a 300 through the work a 12V is capable of it would last about a week. You still see 12V trucks pretty common. When’s the last time you’ve seen a Ford with a 300 going down the road? That’s probably the best gas motor ever made (it almost ties in my book with the 258 inline 6) but they’ve about played themselves out.

[@Jonnydeerhunter]

Hearing that Starter took me back... My Grandpa had an Old 12Valve Cummins Dodge Dually for basically my entire Childhood. I got to drive it in my teens, thing was kinda a dog but man did it sound cool.

[@thoraldshib4393]

till 6 months ago I worked at a shop restoring these terminal tractors, this is way better shape then most we rebuilt

[@number40Fan]

Take the oil feed off of the turbo and point it into the intake of the turbo. Overfill the engine a little to keep it running longer.

[@mphilleo]

Eric, this was a nice midweek pick me up. I love your teardowns, "will it runs," and miscellaneous Miata musings. But this, this was fun. I'm always sad to see an engine blown and I'd be curious what got it to this point. Maybe an engine autopsy would explain. Was it lack of oil? Killer dowel pin? At a minimum, I'm stoked at the possibility of you crashing this into some cars. That would be absolutely wild.

[@JasonMcCord-qk3yb]

6:37 “What is that sound?” Main/rod bearings! I’ve heard that sound…. ONCE. Right before a rod cap on a 5.9 12v I was driving broke. I used to work for a company that had a “Yard Goat” that looked exactly like this one (They all look like this one, more or less…) As a truck driver for the company, we all had to drive it, every now and then. Most of them can be made street legal, so they can run on the street, between yards, or to park/pick-up trailers off the street. Most will do 55 Mph, but they are generally not much fun at high speeds, as they have very stiff suspension and few creature comforts. They are mostly used for pulling trailers on and off the docks. If you want to work on your backing skills as a truck driver, these are the perfect way to do it!

[@Pxsdaemon]

😂Was great to see you having fun creating “inspection ports” instead of being on the receiving end! Morbidly curious on how much that Cummins can take before you tear into it; however, I’d rather see you turn a good profit on the beast!

[@nigelgreer5400]

God this made me laugh! Just think on the fuel saving now it's only a 5 litre engine :) That said, the engine is done! Whilst it's sad, I say finish it and lets see how you killed it. I'm sure you might be able to fit another inspection port. Big fan of yours from the UK :)

[@speedfox6]

Pretty sure I can hear a miss on one of the cylinders at the end there.

[@milstarr]

Prolly just needs a tune up.

[@mahcooharper9577]

Just needs a few revs to help clear the miss

[@Cnightz]

As I sit here and watch the video without reading the comments, I have to believe that oil pressure gauge was working just fine haha.

[@MrDAHHK717]

By far my favorite channel on KZbin. When you parked it and it started rolling I was stressing. The truck driver in me was saying “yellow valve” the whole time haha. Keep up the great work

[@austinschueler8145]

I cant believe it threw a rod and suddenly ran better, really shows how good the 6bt is.

[@paultice610]

Oh well that’s not a big deal. I know somebody that threw two rods on a bobcat. It’s still ran long enough to put it back on the trailer.😮

[@randypierce9485]

I found your channel just by chance about a week ago and now I can't stop watching them. You do a pretty great job of finding out what really went wrong with these engines. I am a nomad that lives down by the river in a van and you really show the importance of keeping that oil changed as I put a lot of miles on my van. I see a pattern of sludge buildup and wonder if synthetic oil is the cause because most of the engines you tear down people would likely use synthetic oil in them..

[@Redleg122]

By the way. I love all of your videos. I have watched your entire channel, twice. Thanks for the content.🤘😎🤘

[@hopingforthebest1.9]

As you've probably figured out, those things get absolutely beat to hell more than just about anything else on wheels Im surprised it ran with a piece of the camshaft missing! You should be thankful it still spins. It can be an absolute nightmare to get to all 6 of those torque converter bolts if it is completely locked up. Ask me how I know 😅

[@chrissiano381]

Ok first.. Those can be used on the roads once they are registered to do so. Their used for short distance maybe a few miles or so depending on how the company that uses them yards are set up. I'm driving a rental right now that is registered for road use at my current job.. That thing can and will run 60 mph.. The one you are talking about is governed at 25 mph because that is how it was ordered since it will not be used on the road.. Your friend gave it to you because of mechanical issues LOL.. That's because most companies are very bad at proper maintenance on those things.. My company sucks at that, this is why we currently are using 2 rentals.. Out of 7, currently there are 4 of our company owned that are in the shop for a extended period of time.

[@phillipgodwin6639]

Would love to see a video of you pulling that Cummings 12 valve out, then another few of you tearing down every piece o the drive line and engine

[@courtneyricks500]

This was great. So unbelievably loud! Loved it

[@kenwillis8487]

You let the SMOKE out! 😅 to anyone that may be upset about the loss of this 5.9, it was done b4 it got to his lot! I had a buddy buy a 5.9 that was knocking real bad , he pulled the engine for the guy and gave $250 thinking he made out like a bandit. Then he tore it down and sent the block and head to machine shop to get a call next day telling him block was no good. It had dress cracks in three places where the internal components were knocking a little to hard to get out!

[@thundermite1241]

Imagine cramming a 8v92t in one these

[@Gersberms]

8:15 yeah **NOW** is when it sounds terrible, all the other times it purred like a kitten 🤣

[@paulhaney6449]

This. iS. Awesome. Eric man you bring out my inner mischievous child who wants to break things then take them apart to see how they work

[@scotttrujillo6649]

See how much sawdust the motor can injest at WOT before the rings and turbo are totally blown 😂

[@HomelabExtreme]

Awesome!! Zip ties and bias plies recommends a healthy amount of ether and redline, it'll freshen up any old tired engine. And PLEASE do a teardown afterwards!

[@proten40]

I worked for GM in the 80's and we used Var-sol to blow up the 5.7 diesels we had to replace. It made the run wide open till they turned loose!

[@dylanyeley]

Used to drive these around for work. Love this video. You’re the best brother would love to intern for you just for the knowledge
