3406b for the win.
I think is the best hd engine.
They still around running now. Kinda like old Honda or Toyota’s. They jut don’t die.
Gcal1956 I have one with 2,200,000 miles. It is still pulling 48k lbs regularly.
@@ArielJRodriguez that's a light load compared to what we pull here in AUS
@@Dilanom That's because of current USDOT regulations. They did begin a pilot program to have certain highways to allow road trains like you Aussies have though, you should expect these older engines to shine once they allow road trains like down under.
I love the 3406e and the n14 because they are simple basic motors that perform well.Built by Americans for americans.
N 14 cumins made me rich man 1 Engine run over 2 million mills 🇺🇸
Built by Americans for EVERYONE.

Just picked up an MTVR with a c-12 thanks to your videos I learned enough to be comfortable with the purchase.
M O S T underrated HD diesel related channel on YT👌. I can't believe he's only at 45k subs.😳
Good work👍, Mr. Adept, I'm always looking forward to the next video.👋☺
Another great video from my favorite diesel RUclipsr
3406B mechanical (like I have in my 1985 KW) with coolant aftercooler is the most reliable engine ever made. So much so, Caterpillar still makes the same basic engine called the 3406C with coolant aftercooler and mechanical injection pump for third world countries that want a reliable generator or pump engine. The 3406C is also made in a natural gas configuration with spark plugs.
Good to know ☺️
Very good to know your opinion. I have a couple of truck driver friends who always specify 6NZ, C-15, not just C-15. Now I know why. Thanks again.
I always thought the 3116 was a pretty good engine, 3306 still the toughest engine ever!
3306 can survive a nuke
Forgot about that motor
My wife and I live in a Country Coach Affinity with a Cat C12. The Coach has 65000 miles on it, but the Engine was Rebuilt 4900 miles ago because of a dropped valve. We love it. Plenty of power for moving this 40klbs along. Thanks for the info! David Allred.
Love cat engines, my favorite is the C12 2KS.
Before I start watching video I think the Cat 3406C is one of the best, lets see
Great video josh! You may already know this, but to address the oil leaks around the spacer plate I use loctite gasket dressing on the top of the block and the bottom of the spacer plate down the drivers side and so far haven’t had any have that nasty little leak there, a cat guy recommended that and so far it seems to work.
Everyone concerned about the heavy duty engines go to 9:50 your welcome great review overall!
Thank you
Have a C12 in my Country Coach Magna. Best RV DP ever made!
Best engines I ever had were c-15 and N14 red top.
the pre-emission C15, N14 and Detroit 60 were the best IMHO.
Gen 2 ISX is a much better engine than the N14 & just as simple
@Horse*Head*Nebula I'm talking about CM570 not CM871
Thx for video FWIW I worked for Cat Dlr as mechanic in mid 70s 1693TA was million mile engine dual overhead cams 4 valve head only nightmare was breaksaver with leaks in convential cab LWB with mega sleeper and road ranger behind was like working in a cave. Always had Owner Operators trying to get you to step up the injection pump and reseal, never did but they were flashing $100. bills trying to getrdone. Guess 425hp wasn't enough hard to believe my GM D'max LML almost has that much hp and it don't clatter, smoke or smell like they used.
Lol, my dad worked at a dealer in the 70's and 80's. Talked about that same thing. Told me the dealership's truck (3408) had it's fuel screw backed all the way out, and the driver would run it by keeping an eye on the pyro. It worked well until apparently a state trooper clocked him doing 70 while pulling a D9.
Good video ! Thank you ! 6 NZ the BEST ! 👍
Все что связанно с cat Батюшка тут как тут, а где же Давидушка он же тоже в теме всегда .
C15?
@@renetobar9579 yes. The c-15 engine, and the best ones are the 6nz serial number type.
My 6nz just blown the head gasket @ 1.311,689.
Great videos learning a lot about Cat engines I myself are a Cummins guy
I practically grew up hearing the 3126 and C7 engines in many of the school busses I rode in elementary and junior high school!
I've owned 4 Cat engines over the yr's, 3176....2 3406-E's.....and finally a 3126-B in my retirement hobby truck....All gave me excellent service especially the 3406-E's it was a sad ending after the C-15's and a downhill ride till Cat ditched the automotive market, glad I had the opportunity to own and work the product until it all went sideways.
3126 is a great little engine. I had a 3126 330 in my straight job and had no problems. loved it.
on the other hand the c7 is garbage lol.
Love the video clip of Pepcon vaporizing for the "Destruction of the week" bit. Nice.
I Love the penny!! Thats some trucker enginuity right there!!
My first truck had a c12 no jakes. Going down the grapevine not to fun. Actually scary to the point that I decided to sell. The buyer just found a route with lower mountain passes and drove it for 5 years until 2010 he got kick out of the Long Beach harbor terminal. New EPA regulations. Overall good engine.
Always liked my 3406E 5EK 475HP
This is my favorite, the 5EK 3406E...it had a slight wine to it! It was hard to die!
Experts everywhere
I'm just curious.what is your opinion?
C18 is a nut!!!! Used in oilfield on drawworks compound and Hydtaulic power units for hydraulic top drives. 711HP
Nice job young man. Very informative
Thanks for the vid..mine is a c15 acert ..twin turbo. 600 hp. NXS... cat customer service said it was one of the good ones..based on serial #... It pushes my 45ft motorcoach
Thank heavens you said the C12 is the best :) I just bought a motorhome with this Engine .. Whew !
Hey my friend I'm looking at buying and older Diesel Pusher one thing I've learned is in the early 2000s c12 cat put nylon plugs to keep the wrist pins in the Pistons,,,,, a lot of those engines went in motorhomes and they would self-destruct magnificently breaking the block around 50,000 miles,,,, Cat knows about this and they've isolated it to a serial number run on c12 2001 - 2005,,,, motorhome manufacturers just buy a bunch of motors and they sit around for years sometimes so I would check the serial number,,,, well some people say there are problems outside of the known bad serial number run but rare,,,,FYI,,,p.s. also those engines suffered from weak wrist pin metallurgy,,,, all this information is known you can do some Googling on RV forums,,, I'm looking to buy a diesel pusher around 2000 to 2006 to avoid emissions crap so I've been spending a lot of time educating myself on these engines,,,, hope you got one outside of that production run happy and safe travels
The c12 was a throw away motor all the big fleets sell them when they come out of warranty at less than 600k miles they turn the cam bearings and oil pressure breaks the oil pump leading to catastrophic engine failure rods through the block etc.
to me the best engine i have ever had is the 3406b
My dad had one in his single screw Mack, good old 4 and quarter, he nicknamed it little kitten big puss
They will literally run forever. Its just like a 12v cummins. They are as simple and well built as any engine ever
Yes, indeed 👍
Great engine. Wish keep engine it wore out rest of the mechanic /welder Tk.
I like the 2ws prefix I always thought it was a little bit better than the 6nz everybody wanted that one But the 2WS is gaining more popularity because it is E log exempt
Yes, runs a 70 pin ecm as well.
18 liter 3408. You can’t beat cubic inches for reliability and pure grunt...plus that sound.
My fire department still runs a CAT C12
3406 b all the way
The water pump on the c12 is gear driven, when the seal in there fails every 150k miles you pump coolant into your oil as well.
Just bought a new C 7.1 marine engine. Guess they made some changes. Hope it works out. Thanks for the cool videos
I have a 3406e 1LW that has been working hard and no problems at all... I have it since 5 years ago just how it came from US and is the best engine I have had... I was a Cummins N14 fan but this 3406 is the best...
I have a 2002 Peterbilt 385 with a 2KS C12, runs great!!
3406E 1MM.... Has a heavier block(about 300 pounds) I would love to see a video on the 14/15 liter 600 hp versions and comparisons.... Great videos and content.... Thanks again
The 1mm and the 5ds are 15.8 basically a C16
The only, ONLY great CAT engines are the 1693 ( the original " four and a quarter " Cat which was the first million mile engine ), the 3406B, 3406E and single turbo C-15. All the rest, well, they were ok or nightmarish. The big blocks were what made CAT a legend in on road/automotive applications.
I had a c15 twin turbo in my hemmt wrecker, never had any problems after i tuned it and the sheer torque it had afterwards was unreal. My pick for non electrical is the 3116, all mechanical and is a pretty bomb proof considering its used and abused by Army troops such as myself on a daily basis. Im retired now but i look back fondly with those two engines.
What I don't like about cat is it has liner protrusion more than any other engine
3406B it was in my 95 FLD the best specially coming up the grapevine in California.
From Jersey, they let you run a mechanical in Ca?
I've never owned a cat, or even a diesel, and probably never will. That being said I find your videos fascinating and have been watching for a couple of years now. Thanks for all the cool content!
David S look into a Volkswagen diesel. Yeah they were a bit sketchy with emissions but if you look past that they are crazy reliable engines that get high fuel mileage.
@@markm0000 My sister has one and takes crazy good care of it but it never doesn't have a check engine light. Unfortunately we live in a state where that is a really big pain in the ass and the dealer is always super expensive. I don't think I can afford that hassle. I'm sure they're not all like that, but I hear a lot of them are.
David S I'm basing my knowledge off the older models from 2008~ish. I'm sure the newer stuff has more electrical problems as most new Volkswagens do. Unless you've got a mechanic friend I would stay away from German cars.
Great info👍
The driver had a blond moment when he put that penny in there! Lol
My first truck wasn't my first choice. Anyway, it had 3176. I bobtailed about 2600 miles averaging 9-105 mph yes I was speeding due to a follow up where my permits expired backwards. Here is what made me a fan as the owner 16.9 miles per gallon at 9-105 mph bobtail. It sipped fuel with a 80,000 GVW 9.4-5 miles per gallon in urban local traffic. My second truck had a series 60 and 2 other 3406 b truck running the same weights the same routes average 6-7 mpg. Loved saving the fuel with the 3176. For medium when I bought my third tow truck I searched the western us for the best rollback i could find used. ALL of the F350S HAD FRAME REPAIRS AND I AM NOT A INTERNATIONAL DIESEL FAN. I found a F600 with a 5x2 setup aluminum bed drove there bought it loaded my car on the bed and drove it home and got 24 miles per gallon with a Detroit 8.2 fuel pitcher. Way better fuel economy made up for the slow drive. None turbo meant so getting there but a extremely durable problem free truck. The fuel savings was incredible. It used less than 1/3 the fuel of the ford super duties about $30,000 per year less and broke way less often with much cheaper repairs.
I'm
Love the torque curve of the 3406 cats in trucks but not a fan of their gear driven water pumps. We run 5 Cat generators with 3406b and c engines at 275hp -350hp. We have one that had 150 hours of actual run time under 50% load that failed, we lost it due to coolant in the oil (wiped the bearings) and had to replace two water pumps on the other ones. Two never weeped out the hole in the water pump. One got caught by annual oil sampling the other started knocking while running during Hurricane Michael. Cat dealer serviced and inspected them two months before. The 3406b model is a 1978 275hp unit, it has close to 3000 hours on it and runs like a dream.
Hard to believe the 3176 is almost extinct in the wild today. I ran RJM in Summerville, SC where the 3176B cylinder blocks were being machined 24/7 from 1994 until 1996. We also machined the pre-production C12 blocks. At any given moment, we had at least 4 different versions of the C12 block castings in process. The issue CAT engineering was fighting with all the casting revisions was the development of cracks in the bulkheads. As it turned out the cracks were being caused by a harmonic vibration being setup by the cam drive gears.
RJM had just enough capacity to keep Mossville in 3176B blocks. With the added load of the pre-pro C12's, we were really falling behind until we made changes that increased throughput of the pacing operations. This of course was at the expense of tool life (and costs). I don't believe I ever got more than 3 or 4 hours of sleep per night the whole time I was down there.
With that one behind us and with just a few years to catch our breath, next up was Texas! San Antonio, Schertz, Seguin....
3406E and 6nz. end of discussion
Mississippi Mud Team B model roll the credits...
Yea no shit sherlock this dude is a cat mechanic obvi every fan boy is over here 6nz and c15s baby! Obviously there great motors in big rigs, do you even know anything about them? Were talking about all motors ,reliability, durability, longevity, power, yes 3406e is great and obviously that an 6nz are the big dogs in the cattle and coal trucks. Awesome. at a mechanic standpoint that doesn't make it the best motor due to every big rig cool ass truck having it, were talking real craftsmen ship and alot of reasons these motors are great other than sounding badass straight piped and and power houses. Damn
Should've mentioned the 3406 c model, now that's the best engine catipiler ever built.
The 3116 was a disaster. We changed the sump (oil pan) to raise the oil capacity, we modified the fuel rail and linkages, changed heads do to the injector sleeve leaking and that was all within the first year of release. Give me a good old 3304 or 3306 any day
Rarely mentioned- I like the 3456.Have a few of them running 500kw gensets.Steady, nonstop 1800rpm power mills.
Lol you've only seen 2 3176s, I own 2 3176 B's. Damn good motors. Just repowered one truck over to a C12 due cost difference in rebuild. I was getting 12 mpg empty on the highways.
IF you are going to exclude the mech engines then you couldn't be talking about the best cat engines.... Electronics are what ruined them,.
Are 3116 decent besides the injection problem?
@@dioniciobedoy8319 if you can deal with the tooling to ream cups and set the rack, yes. Keep the power low and drive. They will give long lives if you keep the overhead adjusted every 30k or so. I like them.
1MM, 2WS, 6NZ , MBN was also good once u got rid of turbo and tune lol

Your knowledge on Cat Engines is impressive. Now my goal is to find some folks that are knowledgeable on Detroit and Cummins Engines. Hopefully they can put 'The Good, The Bad, and The Ugly" on these products in perspective in a similar way that you do.It will make my life a lot easier. Anything built by a human hand and operated by a human hand is going to fail eventually. The goal is to delay that failure as long as possible and yet make the understanding of the failure easy to comprehend.
Pittsburgh Power, Saxonburg, PA
just from my experiences ( heavy duty only ) i’ve found 7cz to be the best engine or for normal work either a 5ek or 2ws cat
I rebuilt cat engines for 30 years , the best cat engine ever built was the 1693 period.
My Dad has been an owner Operater for close to 40 years and he talks highly of the 1693 engine.
That is a FACT
We have a 3176 in a 1995 LN9000. It's the second engine that we have had in this particular truck and the previous engine was a 3176 as well. The current engine is pretty good however the last engine wasn't all that great.
Old school... 👍💪
I think the best engine is a N14 redtop, shots fired!
Best CAT, D-343 1693 T/A 425, of course your Too young to discuss the very Best Class 8 Truck Engine. 3406 - A another great engine no mention. pity.

Which 3406
D-343 is going back is going back nearly 60 years. I spent 16 years in a 988A with the D-343. 87A- 1689. Dam that wad a tough machine.
i'm going to answer this before watching, then watch. Its the same for every diesel engine, ANY OF THE PRE EMISSIONS MECHANICAL ENGINES.
So get a Cummins N14! Right?
Hey adeptape, what are your thoughts on the 3208? I've heard its a disposable pos, but i want to know what you think.
If it's the V8 I think he's covered it already in an older video.
That 3126 injector looks awfully familiar to a dt 466 444
Thanks for sharing always very interesting looking forward to the next video 👍👍
Glad to hear about your favorable estimation of the C9 engine, as our 120M motor graders are equipped with that engine.
you are a big help thank you sir ,I own 2002 western star with c15 475,,,,
Hmmmm beside these CAT 3508 is also a good power engine in all applications including power generation. Let me share the load test video of my own service shop and hands on experience at all.
Thanks for watching the following link if interested and why not to watch my other available videos at channel.
How you think about “ air cell “ installation at front the turbo? I had cat 3406E .
3176b good cat engine bullet proof I have 1,382372miles, and still running strong also I get 7mpg load it. I got rid of my 2 w900l and kept this 350hp little cat. I can't complaint
Could you do a vid about 3406b and 3406c differences, pros and cons ?
Probably in the future, but the short answer is the 3406B is a full mechanical great engine. The 3406C is a 3406B with some electronic junk bolted onto it to screw it up. You can actual turn a C into a B and eliminate some problems.
Mechanical 3406C started at 3ZJ16182 and up, 5KJ07800 and up. PEEC 3406C engines 4CK00846 and up.
I have not worked on or seen a 3406C 5KJ.
Most of the time a emissions change was fixing to occur, thus injection psi starts going up. Not in all cases, but emissions is the driving force. A video would be worthless, its all about if emissions laws are meet . You can go forwards, stay the same year but you can't go backwards. One word EPA. Changing a PEEC to a Mechanical is illegal and the word is EPA. Can it be done, yes. If your caught, EPA. Fine roughly $37,500 or higher if I work on them. Not worth it to me. So basically timing was played with, (fuel) nozzles, (air) turbo, what ever was needed to meet emissions or getting ready for the next big change. Take the last mechanical 3406C built in North America the 8PN. A dog engine just to meet emissions. A lot of carbon was allowed pass the rings and into the oil pan to meet emissions. On mechanical engines you had two dimensional timing, RPM's vs degrees of advance. With the introduction of electronics you went to a three dimensional timing. Thus electronics and EUI's had to come out for CAT to meet emissions. Today common rail is needed to meet emissions.
Hate to be rude but making this type of video you would have to see emissions laws around the time frame. Also you would have to see what parts replaced that was emissions related. Which HP and RPM rating would you use? A lot of combinations was available.
Is there any sealant you can use to prevent leakage between the spacer plate ? I know that "Old Timers" used PERMATEX NON HARDENING sealant on head gaskets on old Cat bulldozers to seal them ! You can reference this @ ACMOC " Antique Caterpillar Machinery Owners Club" website ! Glen.

I'm not too sure what is all the negative feedback on cat 15 acert. I got cat C15 acert 2009 model in my truck and it has done nearly 1.2 million km and I haven't done rebuild to the engine I can't ask for more it has serviced me well for all the years. c15 acert is good engine
Definitely gonna subscribe to your channel
I'm just old school.... 3406B, 3408
Can't beat old school. Simple and reliable as he'll. Can run the dirtiest diesel and they do not care.
Hi! I have two cat 3208 in my boat. They both has gotten very high oil pressure lately. Is this common? Do I need to fix it? I have read that they have a pressure regulator, but I then have to remove the oil pan.. which is a pain
caliwator I would take them to a shop sooner than later you might have a more serious problem.
Hey boss what do you think about c13 ? Is that engine is good ?
How long do the Cat 3208 engines last for?
My favorite engine from Cat by far is the 3116 got a loader (950F II) and two trucks (Kodiak + Topkick) little to no issues
Best engines if you're a mechanic!
Or if you own the truck
Briggs & Stratton
Flatcap007 if they could ship plastic spark plugs they would.
Is the ACERT fuel system (pump + injectors) an internal CAT system? It doesn't look like Bosch's work.
hi i found a clqassic frieghtliner with a c16 in ot what any words on a c16 in a semi truck
Thankyou maestro!
What are your thoughts on the 3304Di engine?
learning heaps about CAT motors from your videos. Any on 3208 motors mate?
I'm no mechanic. But I ran 3208 yrs ago. Short life span. They love throwing rods thru the block. They were referred to as boat anchors.
Can you do a video on just the c16? Doesn't have to be long just cover common issues and fixes.
I have a C12 2KS and I agree it is a very reliable engine..I do have a question though, I wish you would do a segment regarding the "Teflon Buttons" that hold the floating wrist pin in place,
I have heard horror stories about the Buttons failing causing the pin to touch the liner eventually binding up which will cause the piston to turn over knocking a window into the side of the block..
Why would Cat not use snap rings like they do in most of the other engines ???
Brother i want to buy my first truck and my boss is selling a
2004 kenworth Cat c12

Great info, Josh.
Hi, Just found out my 2005 F750 has almost 20000 engine hours, and im looking to replace engine Its a Cat C7 KAL46664, can i swap it with a FMM series engine? I realize ones a 12volt and the other a 24volt system,
Thinking about buying a 79 KW COE with a cat 3406A. Any opinions on that or anything i should look for when i look at it. Any help is appreciated!
Josh! What is the best CAT motor for OTR trucking? As an owner operator I’m looking for a balance of reliability, power, mpg, and low maintenance. Obviously I’m asking for a lot, but would like to get your take. I’m looking for a pre emission motor, and might even go pre 2000. Just found your channel and been binge watching you videos. Thanks for the info!!!!!
3406 b, c, e, c-15( single turbo)
Interesting that you have not seen many 3176. They were popular here in California until the smog laws shut em down. Still see a dew holdouts in trucks and many in motorhomes.
Hey guys! I have a C7 engine family 5CPXH0442HBK with the cylinder head off and the walls on cylinder #3 with some scratches, if not gouges. The original symptoms were huge blowby coming out and blue smoke / oil coming out of the tail pipe. What is weird is that cylinder and head area for cylinder #3 are dry and we found oil on top of the other cylinder / head area. Also, only cylinder #3 exhaust manifold hole is wet of oil and the other ones are dry. Please let me know what are the chances that this engine can be rebuilt, maybe by cutting the walls and putting bigger pistons. Or, what are the margens /specs / limit for cutting the walls. Thanks a lot
The pre emission ones
I'm looking at a twin turbo c15 2007 freightliner classic. Is that engine worth having and are parts hard to find.
Pretty good easy to find
1693 best engine duel over head cam back in the1960 million mile engine
I'm curious do you do you ever discuss the the 1693 and the 3406 A PC. probably not being as they almost non existent any more. but there are few of them still around. I was just wondering because I have driven trucks with these engines in them. and have found them to be quite reliable engines. the 1693 it's main drawback was that it's really heavy. but they were relatively easy to increase the HP on. although then the driver would have watch the pyrometer and coolant temperature more carefully. and I drove one truck in particular that had a 3406 A pre chambered engine for a long time. even though it was a little less powerful it was a really good truck engine. I'm probably showing my age but I thought I would ask anyway. oh I almost forgot another one that was popular as a light duty engine. was the little V8 the 3208 if I remember correctly. Cat produced those engines for a long time. but then ended production of them some years ago.
Great job on the video very interesting
How are the cat 3208 and 3406 in yr opinion?
