RockNRollRoadie47 the intake gaskets are fun, I did mine not long ago, I just done the cam and crank angle sensors yesterday, it's such a strong, reliable engine. I really want a L67 supercharged block.
Happy to see you included the AMC-designed straight six that was used in Jeeps for decades. That sucker really is bulletproof. I worked in auto parts years ago, before becoming a engineer, and guys who had Cherokees or Wranglers with the old 4.0 straight six seemed to have the fewest problems. Only stuff they’d some in to buy was stuff that aged out like hoses or belts when they got old and dried out. Otherwise just basic maintenance. Spark plugs, cap + rotor, wires sometimes, the usual filters. We never sold much in the way of “hard parts” for those engines, because they just ran and ran and ran. I don’t think most people rebuilt them until long past 200k miles. When they did need work, they were very easy to work on.
Nope, if I can't divide the cylinders by four, I... *Something about extreme reliability* (Except for 18 cylinder plane engines) lol This sounds like I've got a lot of experience with engines, when really I don't.(It's just something with the number six, I dislike six speeds, and six cylinders, along with 66 (speed unit of your choice, I use MPH)) Edit: It’s funny that my first motorcycle had a six speed… then I went to a Triumph Bonneville with a 5 speed. I also drive an old school 4.0l Jeep Wrangler, and I think I’m somewhat converted, at least for non annoying Inline sixes and below around 3k rpm. It drives like a little big rig, and feels so fun to drive. I see why an inline six is used, but a V-6 makes no sense when an Inline four with a turbo(or supercharger) can make up for any lost high rpm torque.
The inline 6 being perfectly balanced yet simple is without a doubt the best way to make the most reliable engine possible. I actually desire to design my own i6.
Glad to see the Buick 3800 made your list. I used to build and drag race 1986 and 1987 Buick Grand Nationals and T_Types in the late 80's. I could get 750 hp out of that engine with bolt-ons. We didn't have to do anything in the crankcase... just turbo, intercooler, injectors, fuel pumps, computer, wastegate, intake/exhaust plumbing and heads. We got well into the 10's on street tires. And they never blew!
Richaag Knew a farm family in Iowa that was glad the bodies rotted away. They picked up the slant sixes for irrigation engines. They put a l-p carburetor on them, kept the oil changes up, and had a pivot pump motor that lasted longer than any other motor they had tried.
Ron Fullerton there were several farmers in the Western NY area that used those old slant motors to run irrigation pumps. Totally agree with you, if the basic maintenance was kept up, they’d last for decades.
@JAG I still have all Numbers matching 67 Barracuda Fast Back with the factory 225 Slant 6 in it and revs faster than any other 6 cyl ive ever heard, I am upgrading to a dual point Fuel injection off of the late 80's Crysler 3.9L V6, It should give more HP and TQ.
After graduating from university in 1995 I bought a brand new BMW 325IS with the M3 sports suspension. What a car. I decided to see what I could get out of the 2,494 cc M50 keeping the stock camshaft. Software, Supersprint headers, exhaust, underdrive pulley, cold air intake, larger throttle body, fuel pressure regulator, and much more. End result... 245 hp (crank) at 6,300 rpm and 205 lb-ft of torque at 3,900 rpm. Running it with the rear-end off the automatic version (3.91 vs 3.15) yielded 0-60 times in the 5.7 second range. I´ll never forget pulling out of a toll booth heading down to Philadelphia alongside a new E36 M3 with the 3.2 liter. We went for it and I stayed with him up to about 100 MPH. At the next toll booth he rolled down his window and said, ¨Geez, what do you have in that thing?¨ to which I replied ¨ A tuned 2.5 liter NA¨. Glory days.
I thought e36 M3 evo where banned in the Us??!? I got M3 evo and e36 325i. Trust M3 evo is a beast of car and I think the car you was racing was a fake!!
That was in 1997-98 and the M3 had the S52 engine which was not the euro engine. The S52 was basically an M50 stroked and cammed. It had 243 hp and 236 lb-ft with the 3.23 rear end stock. Keep in mind I gutted my car (no spare tire, etc..). Those M3´s got to 60 in 5.6-5.7 seconds. I did not pull ahead but neither did the other guy, very equal. The euro M3 engine (S54) came afterwards to the US on the E46 M3.
I did a good choice with my first car ! I bought a e46 325xi last month with 150'000km (90'000 miles) and l'm so happy with it ! The car has a exhaust and a k&n air intake, I do 0-60 in 6.8 sec ! ;)
The Ford 4.9 Inline six is well known as an indestructible engine. I knew of one that ran with rod knock for years. Gutless, had common distributor issues, but I don't think I ever saw one fail.
All that ratrod will do is make noise. It might be able to crack past 225whp with a few carbs. You'd need a full build to get a lot more. Add a turbo... now you're talking some real big torque numbers and half the cost!
I worked in a service station in the mid-70s and we had a customer who drove an early 60s Valiant with a slant 6. I can attest, that engine was indestructible reliability. The guy kept the oil changed, gave it regular maintenance and tune-ups, and replaced worn parts. But that engine never failed or broke and burned less than a quart of oil between changes, if that. Chrysler needs that engine today.
Relax people. The title says "10 most reliable" (TEN), not the ONLY reliable 6 cylinder engines in existence. There are plenty of other great reliable 6 cylinder engines to be named that didn't make this list. The guy isn't going to make a hour long video of something that can be split into multiple videos.
author's opinion is all it is. while the old sixes were pretty reliable compared to a lot of engines of their time i do not recall seeing many top 200k miles like you see regularly with more modern power plants that have tighter engine clearances due to better manufacturing techniques. i have seen several chrysler minivans run over 200k without issue. i had a '90 with a mitsubishi 3.0 liter in it that had 180,000 miles on it when i bought it. i seldom ever changed oil (usually 8-10k miles between changes) and sold it a few years later with 250k miles on it and still running strong. wife ran into the people that bought it a few years later and they said it was still running fine.. in fact my family has had several minivans that their engines showed the same reliability. we have a nissan pathfinder with well over 200k on it right now and the engine is still going strong. i loved the sixes of yesteryear from the slant six to the chevy 235 to the ford 240 and such but those engines were built at a time when getting over 100,000 miles was noteworthy due to the differences in manufacturing then vs now. granted the sixes often got well over 100k due to the lower power output and all but today's engines are just more reliable and well they should be after 40 or 50 years has gone by and machining techniques have improved greatly. still i'd take a chevy 235 or a ford 240 any day over these modern power plants. easy to work on easy to fix and no need for computers and sensors and other costly add-ons.
I was.just going to mention the 292 i had it on a 80 pick up and it had 200k miles not km i got it up 350k miles when i finally had to do a rebuild so I decided to modify it a little and its still running lol gotta loves those 6s
Ford 300 Inline 6 is the most reliable gas engine I have ever encountered. I had one with 240,000 miles on it when I bought it ('88 F150). It had an oil pump failure and it ran for 20 minutes before I realized it didn't have oil pressure and shut it off. Fixed the oil pump, changed the oil, let it idle for 25 minutes and even the lifter noise disappeared. Changed the oil again and drove it another 10,000 miles before I decided to drop in a fresh rebuild due to the need to make a cross country trip, but it probably would have made the trip just fine as is. These last miles were with oil pressure low enough at idle to kick on the oil pressure switch when it got up to temp., which is below like 10 psi. Nearly indestructible engines and way overbuilt for their power level. My uncle bought an F250 with 300,000 miles on it with one of these for 300 bucks, did new valve seals then ran it until the frame rusted in half, probably close to 400k. 7 mains and low revs will do that. Lots of very low end torque. Pulls like a freight train below 1000 rpm with peak torque at 1800 rpm. Only drawback to it is that they are notoriously bad on fuel for only a 4.9L and not a lot of horsepower.
The Chrysler slant six engine was one of the most bullet proof 6 cylinder 4 stroke gasoline automotive engines ever produced. A friend of mine has a 1962 Valient with 500k miles and the engine is still running strong without any maintenance other than oil changes, spark plugs, points and condenser and one change of ignition wires.
Glad you included the Barra. Seems not all that many people outside Australia know about it, and it is a phenomenal engine that can take major power upgrades without needing to strengthen the bottom end at all. :-)
That's what I've heard - and not too many engines I know of can reliably reach those levels without needing improvements to the crank or conrods at the minimum. :-)
The early Barra turbo engines had pretty weak conrods, they weren't good for much more than 450-odd hp before they kicked the rods, which is still plenty, but the BF series had far stronger rods in them. The LPG engines had turbo rods in them as well. Tuning Fork had a BF Ute on his dyno making serious numbers but it had the BA rods in it, it did 2 pulls at 500 and something rwkw and on the third it put all the rods right out
1959 Falcon (US), I think you'll find...but that's really just splitting hairs. :-) Pretty awesome for a design from that long ago to still be so good...albeit with a _lot_ of changes as it was improved and modernized. Still, you're right - those old straight 6s are the design basis for the Barra.
Ah great choices here...I can vouch for the AMC straight 6 (later mopar 4.0) and slant 6. I've had 8 of them in the family (6 AMC, 2 Slants) from a Gremlin to Jeep Cherokee XJ. 6 out of the 8 lasted over 300K miles, and ALL of them were running well still with all original hardware before the vehicles had to be scraped due to rust.
Yep I had a 94 Jeep Grand Cherokee with the 4.0L I6. Thing was a beast. Sold it when gas prices got too high back around 2008... was costing $140 to fill and lasting just under a week. Figured what I would spend on gas in 4 months I could buy a fuel efficient car, which I did a Saturn SL1. Always missed the Jeep. Couldn't get that thing stuck.
@@CarAudioObsessions Yeah she's not the greatest on gas. If you gotta travel long distance often I don't blame ya for getting something more fuel efficient. 👍
@@BrodieBr0 ya atthe time was 85km one way to work (50 miles) was getting a little costly. I plan on buying another Jeep but one more suited to do an off roading build, so likely not a Grand Cherokee. See what engine I end up with, may vwry well have the tried and true I6
@@CarAudioObsessions Sounds like a great plan you have! I still daily drive an XJ. got a 1990 Pioneer that I POR-15 coated inside and out so it wont rust away on me. I'm a farmer, so I'm lucky and don't have to worry about long work travel fuel mileage. We work on all of our stuff too so I don't own anything newer than 1993. Got two 1st gen 12v Cummins Dodges on the farm that have been deal reliable too....and they're technically BIG I6 engines too.
@@BrodieBr0 that POR15 stuff is great. My friend is resoring an old Mazda B2200 pickup (dropping in a 2.3 Turbo from Thunderbird Turbo coupe/Mustang SVO/XR4TI) we stripped it down to the frame, box and suspension off etc and cleaned up entire frame and coated the whole thing with the POR15 stuff. Damn frame looks new again. Gonna be a fun little truck hopefully finished over winter, then I'll find something to do a build on and he can help me lol
4.3 is a Chevy 350 with two cylinders cut off. Great motor. The Jeep 258 six is a great torque motor. Both still very much around! Rebuild kit for Jeep still under a $1000. Nice video!
The brazilian-made Chevrolet 250S should be on the list!! It was developed in the 70s as a variant of the older 3.8 that equipped heavy vehicles to be under the hood of the Chevrolet Opala, it made that car a legend in Brazil for its reliability and performance. With it, the Opala won many of the races it participated on, and earned its reputation as a V8 killer. It was a 4.1l straight 6 chain-driven ohv that even today, almost 30 years since the end of its production remais a very popular and desired engine for tunning, being nearly indestructible and very capable of gaining power. The most powerful of them is under the hood of a drag racing Opala that makes 1,500 hps and holds the record of every drag strip it raced on
maaaaate, I have an old AU with the single cam barra variant, (not the twin cam ,like in the terrirtory, ) and yes, they are a donk and a half for sure, freight trains of torque and towing power. Tows the boat like theres nothing behind it. MInes just run in at 300,000 kms :D pity Ford Australia went broke. We will no longer see these beautiful motors in any new cars now.
@@davesboatingfishing The SOHC in the AU was called the Intech and in my opinion is the best motor they put in a falcon! I took mine to 360,000km before someone wrote it off for me but it's still parked up and used as a farm pig haha it triggered my love for inline 6s and I ended up replacing it with a Merc W140 with the M104 I6
I once owned a 1967 VE Valiant (Australia) with the slant-6 motor. They were super strong and gutsy. Legend has it that Chrysler replaced the slant sixes with the 245 and 265 hemis because they weren't making any money on parts for the 225s.
The AMC 232 and variants, (258, 4.0) were produce for 42 years, 1964-2006. I own 2 cars with 232s and I will take them any day over a V-8. They have plentry of power, and are light on the front end which makes the cars balanced, fun and very enjoyable to drive. And, they are bullet proof.
It was for sure. People back in the day, said they called it the 225 because it would go 225 thousand miles. That and the dodge 318 were some of the only motors that I used to see make it over 100,000 miles without issues.
@@greybone777 There was a time when companies cared about customer loyalty and produced long-lasting products, then a younger generation began to take the reigns of control over these companies and wanted a faster return of profits, so they came up with a new plan, built-in or planned obsolescence, which they have down to a science that various products malfunction shortly after the warranty ends. This comes from years and years of data on how long various materials hold up to the stresses of use. so that they can literally engineer a product that will need repair or replacement shortly after the warranty is up. To build into products planned malfunction is dishonest, but what are we to do when all of them are doing it, there is no jumping ship to a competitor when the competitor is doing the same thing.
Chrysler Australia's Hein six in 215 245 and 265 displacements were considered the best engines out of the three large family car players with Ford and GM Holden 1970 -1981. They succeeded the slant six in the Australian market Valiants. The triple Weber version of the 265 used in the Aussie Charger two door fastback made it the world's quickest accelerating production six cylinder at the time.
Chrysler slant 6 is my vote. For 30 years there was a local cab company that only used slant 6 Motors in their cars. Hundreds of thousands of miles of Northern city conditions didn't even phase them. Visio has the thickest accent that I can easily understand. And the most interesting videos always very accurate and well-researched
I was a car mechanic thirty years ago and I will remember till my dying day an occasion when a Chrysler slant six came in to be serviced. Probably the smoothest idling engine I ever saw.
Yes , they where a pretty good old bangers , i had a couple cars with chrysler slant sixes AP5 and VC valiant models , australian built , the only gripe i had was , they seemed to go through manifold gaskets periodically for some reason , maybe something to do with the big ugly manifolds on them , other than that though , reliable old buggers . Come to think of it i also had a cm valiant wagon with the 265 CI ELB, that was actually pretty car good too . The only thing that spoiled all those cars was the crappy chrysler torsion bar suspension on the front , NVH just was not up to scratch compared to other brands imo .
Sorry but my experience says otherwise. I'm steadfast at maintenance on all of my cars and trucks right down to the tire air pressure. I had the 300 in two different trucks Couldn't keep them from leaking oil. Fix one gasket and another would start leaking. And no I didn't have pressure in my crankcase. Plus I experienced major HP falloffs on both after about 50K. On one I couldn't replace the oil pan gasket unless I completely removed the engine. I had nothing but trouble with them.
@@johnallen9439 just keep the oil topped off, ffs. And clean your god damn injectors, or carb depending on what you have. So many people whine because they dont take care of a engine properly
@@MilesPrower1992 The American Motors Corporation (AMC) straight-6 family of engines was used in AMC passenger cars and Jeep vehicles from 1964 through 2006
I had a 71 Dodge Demon, 225 "leaning tower of power" Slant 6. The Chevrolet mechanic said it was THE best engine ever built. I believe him. My daily driver now is a 93 Jeep Grand Cherokee, 4.0 inline 6. It has 240,000 miles on it, (low actually for a 28 year old vehicle), and it runs just as good now as the day it was bought. Only engine work done was replacing the harmonic balancer. Freaky thing about this Jeep, the AC has never had any freon added and it still blows cold as ice!
Between my son and I we've had a lot of Jeep 4.0 ltr. 6cyl. engines and those things are torque monsters and live forever. One of the very best engines ever made.
300 6cyl Ford, excellent engines, 6 cyl and 7 main bearings, you can buy a steel timing gear set and it comes with instructions for an extra oil tap to run oil directly on the gears. The 225 slant 6 cyl Dodge- Plymouth was also tough.
I was waiting and then finally it was on the list at the very end, GM'S 3800. I've owned about 7 cars with that engine not all the original some were series 2 and series 3. Basically bulletproof with proper maintenance.
Missed opportunity having it be in envoys and cars like that a straight 6 in a Camaro would have been cool proper aftermarket and support would make these motors real threats
You are one of the very few channels where I watch every single video that gets posted. Great informative quality, pacing, and topics. Each time I watch one I know I'll be learning something new and that alone is worth it. Keep up that good work man, and have a great New Year!
BIGBLOCK5022006 That reminds me, At a junkyard near me, the Car crusher they have is powered by a Chrysler 225 Slant 6, hes had it for years, runs like a top!
Anthony Ballmann That's the beautiful thing about the old school engines like the Chrysler Slant 6 and the Ford 300. You could beat the hell out of those engines and they come out smiling and say "Thank you, Sir! May I have some more?".
I love the AMC inline 6. I've had 3 Grand Cherokees with that engine. I had 2 97TSi and 1 03 Laredo. If it was cold or had been a few days, sometimes they would take a few seconds to start up and you had a nice old school highland starter sound lol. Perfectly balanced and rather hypnotic at 1800-2100 rpm traveling the open roads. Had one from 2000 to 2019 I'll have another 😉
Former boss of mine had a Ford van with a 300. Body and frame finally rusted so much it was starting to “inchworm” at 400,000 miles but the 300 was still going strong when it finally had to be retired
The one that was in our 1981 Chevy Malibu "Iraqi taxi" was amazing! The only part I can specifically remember my father changing on it was the starter. That thing was bulletproof, and still going strong when we eventually got rid of it to buy a van.
Ripplin you had a genuine Iraqi taxi?! Cool! Yeah, they had a carburetored version Of The GM 3.8 litre V6 (which is the last engine on this video 😉) which only made about 82kw, but was bulletproof. It's the same basic engine in my Holden Commodore Ute, that I drive to this day (I'm in Australia) but with fuel injection and a few other upgrades that almost doubled the power to 153kw. Damn good engine...
Man, I remember in Iraq how those were about the only American cars I'd see. The other taxis were Ladas and Toyotas and Nissan, but they loved them some Caprices!
@@banokles Besides that 3.8 (Buick 231 cu. in. design), Malibus, in Canada at least, could be had with a Chevrolet design 229 cu. in. V6, which also worked out to 3.8 litres, and gave occasion for confusion when getting parts. And mention of "Iraqi taxi" dredged up a faint and shaky recollection of (I don't think this is an urban legend) being told, around that time, that a number of new Malibus destined for Iraq or Iran were languishing on the dock in my eastern Canadian city, Saint John, New Brunswick, because of turmoil where they were to be sent. They weren't available to us, though, maybe not certified for our regulations. Also, though they were said to have A/C, I think, for some inexplicable reason, they didn't have heaters. That does sound like an urban legend, doesn't it?
I have two AMCs with 232s and can say they are great engines. The V-8s were great as well, but the six was lighter on the front end and makes the car fun to drive.
An engine that deserves a mention here is the 2nd generation Chevy inline 6. The 194, 230, 250, and 292. They ran from 1962 (194) all the way to 2001 (292). They were put in just about everything from trucks to cars, forklifts, generators, boats, and more. Next to impossible to kill. I had a 1965 250 that went well into 500k miles before it wouldn’t make freeway speeds, but it could still putt around town.
Also, I think the Nissan VQ deserves a shoutout. I owned an Infiniti G35 for 13 years, put over 200k miles on it, and that motor never needed service once - unless you count the stupid cam position sensor (I don't). To give you an idea of how I ran this car, over the years I had four clutch jobs done on it.
@@chuckschillingvideos 100% luck my friend, those engines needed a hard break in to seat the rings so they didn't burn oil. Most cars didn't get that and burned oil the rest of their lives.
Ahh, the Buick 3800. I have one of the later years of the engine - the Series II. So smooth and crazy reliable. Only 3 issues: the gaskets could be eaten away by Dexcool (GM specific coolant), the upper intake manifold can leak quite badly, and the recall that involved the valve covers leaking oil onto the exhaust manifold - which would catch fire. Apart from those three issues.....I love the engine.
I had a '69 Plymouth beater "snow car" for winter use in Cleveland. I left Cleveland in 78 and decided to leave it there for nature to finish dissolving it. The only thing that had any value at that point was the slant six which a lot of the plugs would fire on a dry day and a '70 U-Haul trailer license plate. Some nice young man decided he wanted a project to learn about cars and he offered a $75.00 for it and I sold it . I bought it in '74 for $50.00 so all in all it was probably The first and only car I've owned that actually appreciated 25% over 4 years of daily use. The motor would buck like a jack hammer when the humidity was high and in the rain it would drown out the lifter clatter. As long as there was some oil / coolant mixture running through it's inners it would continue moving on it's own.
I've had the AMC 232 and the Dodge 225 slant. Great engines although the AMC was a bit underpowered for the AMC Ambassador. Just change the oil regularly.
@@fartsoundeffect5013 But you're biased, you are going for the one that sounds most like a fart! ;) The Barra is much newer and better in every way, look it up and see what people do with them. ruclips.net/video/I_szwWlh7jc/видео.html
One of my favorites was a 2.8-4.0 Litre Cologne motor. My 2.8 I modified a bit and got in a fair bit of trouble with. Taught my son how to drive (sideways ) with the 4.0 in a B4000 with a 5spd.
The Chrysler slant size was unbelievably reliable. Back when I was a kid, most other engines would be burning oil and having issues by 100K miles, but old slant sixes in Dodges and Plymouths just seemed to have no problem going 150K miles and running great. I wonder how well they would do today with modern synthetic oils. (Oils back in the 60's were crap as compared to what we have today!) The old Slant Six could be hopped up to perform like a V8. I remember a couple Dodge Darts making several guys with V8's feel pretty silly in impromptu drags.
Jonathan Morley and stovebolt 6 it was cancelled for being reliable, the only we have upgraded (it’s only 5 years newer engine) is it was run without oil
Back in the 60s, the Ford 300 cu in, would regularly last forever. I know one guy who had 600,000 miles and had never done anything but oil changes. With today's oils, it would easily go a million miles.
@@markgillies1834 I have a 1978 Ford Granada it has three bad cylinders they're going to pull it out and replace it with a 300 straight 6 same year. I am going to save the money and rebuild the 250 I think the head is bad as well I think it's warped still starts and drives though.
Im so happy the 3800 v6 was #1 on this list. Even though a lot of the GM cars they were attached to were jalopies and could easily turn into rustbuckets, that block was built like a TANK. My dad had a '93 Chevy Lumina that had lost the hubcaps, had half of the exhaust system rusted away, half of the electronics deteriorated, and rust ALL over the body, but by the time he got rid of it in 2013, the odomoeter read ~325k miles and that motor was still purring like a kitten.
Yeah, ummmm NO. The biggest engine on the Lumina was the Chevy 60degree V6.1991-1994: 3.4 L (207 cu in) LQ1 V6. The 3.8 wasn't used until the 1998 model year. Nice try. And yes, I was an engineer at GM.
I had a pretty awesome ‘72 C10 with a 250 six and a later four-speed, it had over 200,000 miles, didn’t use a drop of oil, started instantly and got like 17-20 mpg, which is pretty impressive for an old truck with no overdrive. It could’ve been rebuilt at some point, it looked suspiciously clean, but they’re known to be pretty tough.
WOW one 15 yr old with 270 k there are motors out there that run for 30 yrs and over 1 million miles, get back to us when that chevy hits 1 million with no internal work done,never happen. 270 k is normal today, had that and more on many motors over the years. real longevity is 750k plus miles with out touching the internals of the engine. Then you join the elite of lasting motors. Kids today are impressed so easily. 270k LOL I got that and more on a 4 cylinder motorcycle that redlines at 11 grand and sees it often.
Think the Buick 3.8 V6 is worthy of mention here, damn good engines!! The Holden straight 6 engines were good too tough reliable long lasting!! The older Merc 6 cylinder engines run Forever! The Jag XK engine design dates back to 1949 ( i could be wrong ) good engines quite easily tuned up but they were a heavy engine cast iron block!!
Went from a 275hp high compression NA all aluminum 2.3lima in my mustang 2. That motor that was 20k is on a stand under a fire blanket. Just recently my new crate motor finally showed up to the house. Literally 2 days ago. A merc 7liter sb4 is what is in the makings for the little mustang 2. Anyone who doesn’t understand what that is. Mercury marine. Took there chevy big block, short block motor they use in all there high performance inboard motors. Instead of 9liters like most. Kept it at 7. Throw there own in house DOHC heads on it. Such an amazing motor merc has been making. It’s been offered as a crate motor for quite a few years now. Sounds so amazing !!!
Bandit 3076 I didn't think the AU got the barra, wasn't it the BA that first had them? See plenty of Barra's for sale with over 800,000k's crazy engine
The AU had the SOHC Intech, that was the truly simple bulletproof engine, I still own mine. The DOHC Barra was introduced in the BA. Almost identical block and bottom end but the addition of a lot of electronics and variable cam/valve timing and an extra cam shaft made it much less resilient to abuse! Still get 1,000,000km out of one with half decent service intervals though...
Sean Kretschmann I retired an FG after 7 years service as a Sydney cab with 982k on the clock. Sadly I can’t see the Camry hybrid that replaced it going the distance.
Unfortunately nearly all manufacturers are moving away from inline six engines and going to V6, which is a shame because historically inline six's have been the most reliable and smooth type of engine.
How many v6 engines have lasted as long as the inline6 ? None of them . The inline has the smoothest power as compared to the v6 with the least amount of vibration .
In nerd-speak, an inline 6 is inherently balanced in that (if you perform the calculations) the reciprocating masses have no 1st order or 2nd order vibrations (or 3rd order, or 4th...). Obviously, a V12 falls in this category, too.
Right? I'm pumped we're finally getting them in the states. Also if gm would of advanced the 3800 like ford did their 3. Ecoboost gm would be taking it in.
3.8 Buick fireball is a bad ass motor it's my personal favorite and you didn't talk about it getting a turbo or the supercharger. Grand national or pontiac GTP or it smaller brother the 3.3 which also got a turbo. A lot of performance and military history in this motor. My camaro has one with 5 speed gearbox. My monte Carlo did too and my cousin had a 1992 oldsmobile toronado trofeo with a supercharged 3.8 it was a beast all the way to 370.000 miles.
kain hall just got rid of an 03 Bonneville with 300k on it. I didn’t get rid of it because of the motor I got rid of because of the chassis electrics. I ended up with a 99 silverado with a 4.3 in it.
I like the 3800 V6 as well have a 03 LeSabre it only has 115kmiles on it but plan on keeping it till it has well over 200k miles and see noreason it wont make it with no major rebuild
Jaguars AJ16 engine seen in the x300 series XJ is the most reliable jaguar engine produced, even the electronics aren't plagued with jaguars "cost cutting" methods because it was produced under Ford, with the possibility of it being used as a diesel and petrol block!
For more information on this engine, look to AJ6 engineering, they deal exclusively in Jaguar engines, and they are the last word in Jaguar Tuning www.jagweb.com/aj6eng/
Producing a block that could go diesel or petrol, sounds like a cost cutting measure to me, though. Besides that, I am surprised to see Jaguar as a reliable engine maker here. I get a bit suspicious about the quality of an engine when there is a well-known company dealing only with engines of one make.
I had a Ford 1/2 ton pick up with that 300 6 , it just kept going and going 430,000 miles and the engine was never opened up . Only thing wrong with that truck was the steering gear bax had to be replace ( $17.50 ) from Pick-a-Part . Sold the truck and the engine was taken out to tun a portable sawmill. I averaged 28 mile to the gallon, Imperial gallon . Not to shabby for an old pick up
glad to see the amc / jeep motor on the list. 20+ jeeps owned by my family over the last 25 or so years and i cant remember a single major engine repair. just maintnance and the occasional bolt on like waterpump or starter. a few have seen 300k+ befor being sold only to see them years later still trodding on.
#2: In keeping with our Made In America narrative, don't forget the AMC I6. Also a really great engine that will take care of you as long as you take care of it.
What about the 4.0l jeep i6. That thing will tick after the last man on earth dies. I know, cause I have one, a 95 jeep Cherokee. Only thing olive ever do to the engine is change oil
The 4.2L evolved into the 4.0L the video kinda hinted at that when he said it was made into the 21st century. I believe the last year for the 4.0L was 2006
The ford 300 I-6 was a great engine, I knew alot of delivery van owners, 850,000miles with just fuel pumps and starters replaced. The old UPS brown trucks, some were 25yr old,you don't see them much any more,UPS would scrape them(they would not sell their brown vans), also the chevy 292 I-6 was a great engine(UPS used them also). I agree with your followers that the AMC-Jeep 4.0 wasn't mentioned, that it also was a great engine.
Once Ford put port EFI on the 4.9s, they were unstoppable. When I worked for GoodYear, we had a fleet of mid 90s E250 extended wheel base vans which we used for delivery vehicles all around Chicagoland. We would scrap the vans due to body rot at around 3-400k, but never once changed an engine. They were gutless and didn't like to rev, but they never broke. When Ford switched to the 4.2 V6, we had nothing but problems. Long live the cast iron king!
Ford Australia had issues with the Ford 300. Not reliability, but the fact that they were so heavy on fuel. They took their own 6 cylinder, developed from the 170 "super pursuit" 6 cylinder first seen in the first US Falcons. Over time, they were bored, stroked, given fuel injection, double overhead cams, cross flow heads and turbochargers. They developed a specific version for the F-series. Known to most as the 250 truck engine, it had a high compression, cross flow head, 250 cubic inch capacity, and electronic ignition. I used to work at a remote roadhouse, and the tow truck was an F350 with one of these. It had diesel-like pulling power, and was as reliable as sunrise.
Shoutout for the.. iron Duke.. the ford straight six 300 With a single barrel carburetor the best motor Ford ever made I had a Ford F-150 the shackles rusted off the rubber between the frame and the body disintegrated to nothing truck set sideways rust all the way through the chrome bumpers rust holes all over The body and frame doors wouldn't shut properly tailgate wouldn't shut properly but it still ran perfect till the very day I had to scrap it.
My friend in Australia had an XD Ford Falcon as a taxi ..it had 1.3million kilometres on it when a truck ran a light and wrote it off .. original block, on its second cylinder head and second pair of front disc brakes..it ran on LPG .. 4.1Litre ohv straight six !! Beat that !!
I drove my grandpa's 1 owner , all original 71 Ford F100 SB 4x4 with it's 300 I6 for 18 years 6 days per week and 78 miles 1 way to work. The truck had 351,678 miles on it when 1 began restoring it . Not once has the truck ever broke down since brand new. It's always had preventative maintenance and service. But it is a bit more truck then it ever was now. The 300 I 6 still ran good but definitely lacked power. Adding a 600 Cfm 4 barrel carb , bigger intake, a ported 240 I6 head, comp cams performance cam, roller rocker arms, bigger valves header and blow through turbo charging and 9 lbs of boost to the 300 makes it unbelievably awesome . I could go more boost reliably but it is plenty powerful with the 9 lbs and other mods

RockNRollRoadie47 the intake gaskets are fun, I did mine not long ago, I just done the cam and crank angle sensors yesterday, it's such a strong, reliable engine. I really want a L67 supercharged block.
VisioRacer have a great new year boss.
Happy to see you included the AMC-designed straight six that was used in Jeeps for decades. That sucker really is bulletproof. I worked in auto parts years ago, before becoming a engineer, and guys who had Cherokees or Wranglers with the old 4.0 straight six seemed to have the fewest problems. Only stuff they’d some in to buy was stuff that aged out like hoses or belts when they got old and dried out. Otherwise just basic maintenance. Spark plugs, cap + rotor, wires sometimes, the usual filters. We never sold much in the way of “hard parts” for those engines, because they just ran and ran and ran. I don’t think most people rebuilt them until long past 200k miles. When they did need work, they were very easy to work on.
I've had four vehicles with the 7-main bearing AMC inline six. Rugged and dependable. Thanks for featuring it!
The inline 6: perfectly balanced, as all things should be
Rick S Boxer engine sucks
Nope, if I can't divide the cylinders by four, I... *Something about extreme reliability* (Except for 18 cylinder plane engines) lol
This sounds like I've got a lot of experience with engines, when really I don't.(It's just something with the number six, I dislike six speeds, and six cylinders, along with 66 (speed unit of your choice, I use MPH))
Edit: It’s funny that my first motorcycle had a six speed… then I went to a Triumph Bonneville with a 5 speed. I also drive an old school 4.0l Jeep Wrangler, and I think I’m somewhat converted, at least for non annoying Inline sixes and below around 3k rpm. It drives like a little big rig, and feels so fun to drive. I see why an inline six is used, but a V-6 makes no sense when an Inline four with a turbo(or supercharger) can make up for any lost high rpm torque.
@@Brandon0083 only if you dont upgrade the stock head and valve cover gaskets then your in business
Thanos should’ve got rid of bmw too
Fbi open up
The inline 6 being perfectly balanced yet simple is without a doubt the best way to make the most reliable engine possible. I actually desire to design my own i6.
Agreed, something to parallel or even surpass the venerable 2JZ
Glad to see the Buick 3800 made your list. I used to build and drag race 1986 and 1987 Buick Grand Nationals and T_Types in the late 80's. I could get 750 hp out of that engine with bolt-ons. We didn't have to do anything in the crankcase... just turbo, intercooler, injectors, fuel pumps, computer, wastegate, intake/exhaust plumbing and heads. We got well into the 10's on street tires. And they never blew!
Had a 225 Slant 6 in a 1975 Plymouth Scamp. The engine was bulletproof, which is a good thing because the rest of the car rusted out right around it.
Richaag Knew a farm family in Iowa that was glad the bodies rotted away. They picked up the slant sixes for irrigation engines. They put a l-p carburetor on them, kept the oil changes up, and had a pivot pump motor that lasted longer than any other motor they had tried.
Ron Fullerton there were several farmers in the Western NY area that used those old slant motors to run irrigation pumps. Totally agree with you, if the basic maintenance was kept up, they’d last for decades.
I had a 1966 barracuda with the slant 6 and three on the tree the car rusted to the ground but the engine still never used oil
@JAG I still have all Numbers matching 67 Barracuda Fast Back with the factory 225 Slant 6 in it and revs faster than any other 6 cyl ive ever heard, I am upgrading to a dual point Fuel injection off of the late 80's Crysler 3.9L V6, It should give more HP and TQ.
death proof unstoppable
After graduating from university in 1995 I bought a brand new BMW 325IS with the M3 sports suspension. What a car. I decided to see what I could get out of the 2,494 cc M50 keeping the stock camshaft. Software, Supersprint headers, exhaust, underdrive pulley, cold air intake, larger throttle body, fuel pressure regulator, and much more. End result... 245 hp (crank) at 6,300 rpm and 205 lb-ft of torque at 3,900 rpm. Running it with the rear-end off the automatic version (3.91 vs 3.15) yielded 0-60 times in the 5.7 second range. I´ll never forget pulling out of a toll booth heading down to Philadelphia alongside a new E36 M3 with the 3.2 liter. We went for it and I stayed with him up to about 100 MPH. At the next toll booth he rolled down his window and said, ¨Geez, what do you have in that thing?¨ to which I replied ¨ A tuned 2.5 liter NA¨. Glory days.
Rafael Lastra com I wish i have my first car just like you
I thought e36 M3 evo where banned in the Us??!? I got M3 evo and e36 325i. Trust M3 evo is a beast of car and I think the car you was racing was a fake!!
That was in 1997-98 and the M3 had the S52 engine which was not the euro engine. The S52 was basically an M50 stroked and cammed. It had 243 hp and 236 lb-ft with the 3.23 rear end stock. Keep in mind I gutted my car (no spare tire, etc..). Those M3´s got to 60 in 5.6-5.7 seconds. I did not pull ahead but neither did the other guy, very equal. The euro M3 engine (S54) came afterwards to the US on the E46 M3.
Those numbers seem really low for that amount of work. I would have thought closer to 300 hp
I did a good choice with my first car ! I bought a e46 325xi last month with 150'000km (90'000 miles) and l'm so happy with it ! The car has a exhaust and a k&n air intake, I do 0-60 in 6.8 sec ! ;)
The Ford 4.9 Inline six is well known as an indestructible engine. I knew of one that ran with rod knock for years. Gutless, had common distributor issues, but I don't think I ever saw one fail.
Homebrew Subaru gutless?stick a holley n headers on er
C the ratrod one?triple strombergs.
All that ratrod will do is make noise. It might be able to crack past 225whp with a few carbs. You'd need a full build to get a lot more.
Add a turbo... now you're talking some real big torque numbers and half the cost!
Homebrew Subaru there is no 4.9 six highest is 4.1.Fuck outta here
Yeah OK
Just straight 6's. BMW knows why they don't build V6's 🤞🏽
And the sounnnnd
Yes. BMW never built a V6 or front wheel drive car
@@hostileenter1605 😂bmw F40 135i is front wheel
Thank god. If they had made a V6 it would be the most unreliable V6 ever made.
indeed
I worked in a service station in the mid-70s and we had a customer who drove an early 60s Valiant with a slant 6. I can attest, that engine was indestructible reliability. The guy kept the oil changed, gave it regular maintenance and tune-ups, and replaced worn parts. But that engine never failed or broke and burned less than a quart of oil between changes, if that. Chrysler needs that engine today.
They discontinued because of Front wheel drive. It was too long to work.
A quat is about 1L. That's a lot oil between services. That would be about 20 to 25% of the total capacity.
They dont build like that anymore , 318 v8 was a great engine also
@@faolan1686 Not back then it wasn't a lot. Many engines burned a whole quart and more in a thousand miles.
@@jrg7951 They need to discontinue Front Wheel Drive as well. Rear Drive gives better dynamics. Plus it is easier to work on.
Relax people. The title says "10 most reliable" (TEN), not the ONLY reliable 6 cylinder engines in existence. There are plenty of other great reliable 6 cylinder engines to be named that didn't make this list. The guy isn't going to make a hour long video of something that can be split into multiple videos.
AkLG55, understood. But I truly feel the 1hz is done an injustice by missing out on a mention.
author's opinion is all it is.
while the old sixes were pretty reliable compared to a lot of engines of their time i do not recall seeing many top 200k miles like you see regularly with more modern power plants that have tighter engine clearances due to better manufacturing techniques.
i have seen several chrysler minivans run over 200k without issue. i had a '90 with a mitsubishi 3.0 liter in it that had 180,000 miles on it when i bought it. i seldom ever changed oil (usually 8-10k miles between changes) and sold it a few years later with 250k miles on it and still running strong. wife ran into the people that bought it a few years later and they said it was still running fine..
in fact my family has had several minivans that their engines showed the same reliability.
we have a nissan pathfinder with well over 200k on it right now and the engine is still going strong.
i loved the sixes of yesteryear from the slant six to the chevy 235 to the ford 240 and such but those engines were built at a time when getting over 100,000 miles was noteworthy due to the differences in manufacturing then vs now. granted the sixes often got well over 100k due to the lower power output and all but today's engines are just more reliable and well they should be after 40 or 50 years has gone by and machining techniques have improved greatly.
still i'd take a chevy 235 or a ford 240 any day over these modern power plants. easy to work on easy to fix and no need for computers and sensors and other costly add-ons.
and the 292
Yezu, alongside the om606, I think the m103 from mb are also reliable too
I was.just going to mention the 292 i had it on a 80 pick up and it had 200k miles not km i got it up 350k miles when i finally had to do a rebuild so I decided to modify it a little and its still running lol gotta loves those 6s
long live the straight 6
ruclips.net/video/ARLS8yAo6Vg/видео.html
Long live the slant 6
@Rodrigo Ribeirocorrection: they are the best
Ford 300 Inline 6 is the most reliable gas engine I have ever encountered. I had one with 240,000 miles on it when I bought it ('88 F150). It had an oil pump failure and it ran for 20 minutes before I realized it didn't have oil pressure and shut it off. Fixed the oil pump, changed the oil, let it idle for 25 minutes and even the lifter noise disappeared. Changed the oil again and drove it another 10,000 miles before I decided to drop in a fresh rebuild due to the need to make a cross country trip, but it probably would have made the trip just fine as is. These last miles were with oil pressure low enough at idle to kick on the oil pressure switch when it got up to temp., which is below like 10 psi. Nearly indestructible engines and way overbuilt for their power level. My uncle bought an F250 with 300,000 miles on it with one of these for 300 bucks, did new valve seals then ran it until the frame rusted in half, probably close to 400k.
7 mains and low revs will do that. Lots of very low end torque. Pulls like a freight train below 1000 rpm with peak torque at 1800 rpm. Only drawback to it is that they are notoriously bad on fuel for only a 4.9L and not a lot of horsepower.
Yes but the would get 12 - 14 MPG running empty or hauling a ton weight it didn't matter
They were also gear to gear driven no timing chain they never went out of time
The Chrysler slant six engine was one of the most bullet proof 6 cylinder 4 stroke gasoline automotive engines ever produced. A friend of mine has a 1962 Valient with 500k miles and the engine is still running strong without any maintenance other than oil changes, spark plugs, points and condenser and one change of ignition wires.
Glad you included the Barra. Seems not all that many people outside Australia know about it, and it is a phenomenal engine that can take major power upgrades without needing to strengthen the bottom end at all. :-)
aussiebloke609 swap out the valvesprings and turbo and you're good for 600+whp. cheap as all fuck too
That's what I've heard - and not too many engines I know of can reliably reach those levels without needing improvements to the crank or conrods at the minimum. :-)
The early Barra turbo engines had pretty weak conrods, they weren't good for much more than 450-odd hp before they kicked the rods, which is still plenty, but the BF series had far stronger rods in them. The LPG engines had turbo rods in them as well. Tuning Fork had a BF Ute on his dyno making serious numbers but it had the BA rods in it, it did 2 pulls at 500 and something rwkw and on the third it put all the rods right out
The Barra is based on the old 1960 Falcon 6 from the US. The 144, 170, 200 and 250.
1959 Falcon (US), I think you'll find...but that's really just splitting hairs. :-)
Pretty awesome for a design from that long ago to still be so good...albeit with a _lot_ of changes as it was improved and modernized. Still, you're right - those old straight 6s are the design basis for the Barra.
I love that 300 Ford hot rod in the beginning, it's so unusual but so great at the same time.
292 Chevy should at least get an honorable mention, great 6 cylinder engine
Probably the best and strongest pulling engine that GM built.
Ah great choices here...I can vouch for the AMC straight 6 (later mopar 4.0) and slant 6. I've had 8 of them in the family (6 AMC, 2 Slants) from a Gremlin to Jeep Cherokee XJ. 6 out of the 8 lasted over 300K miles, and ALL of them were running well still with all original hardware before the vehicles had to be scraped due to rust.
Yep I had a 94 Jeep Grand Cherokee with the 4.0L I6. Thing was a beast. Sold it when gas prices got too high back around 2008... was costing $140 to fill and lasting just under a week. Figured what I would spend on gas in 4 months I could buy a fuel efficient car, which I did a Saturn SL1. Always missed the Jeep. Couldn't get that thing stuck.
@@CarAudioObsessions Yeah she's not the greatest on gas. If you gotta travel long distance often I don't blame ya for getting something more fuel efficient. 👍
@@BrodieBr0 ya atthe time was 85km one way to work (50 miles) was getting a little costly. I plan on buying another Jeep but one more suited to do an off roading build, so likely not a Grand Cherokee. See what engine I end up with, may vwry well have the tried and true I6
@@CarAudioObsessions Sounds like a great plan you have! I still daily drive an XJ. got a 1990 Pioneer that I POR-15 coated inside and out so it wont rust away on me.

Got two 1st gen 12v Cummins Dodges on the farm that have been deal reliable too....and they're technically BIG I6 engines too.
@@BrodieBr0 that POR15 stuff is great.

Damn frame looks new again. Gonna be a fun little truck hopefully finished over winter, then I'll find something to do a build on and he can help me lol
I had an 87 ford van with a 300 ci straight 6 . I bought it new. I sold it 10 years later with 458,000 miles on it, still running.
I'm glad you mentioned the Australian barra, beautiful motor.
4.3 is a Chevy 350 with two cylinders cut off. Great motor. The Jeep 258 six is a great torque motor. Both still very much around! Rebuild kit for Jeep still under a $1000. Nice video!
But it's very rough and not smooth
The nissan L series engine was extremely reliable, mine ran until 400,000 miles before I rebuilt it after a lot of power lost and excessive blow-by
One testament to an engine's reliability is when you find then in other equipment. I once drove a Massey 305 combine that had a slant six engine.
The brazilian-made Chevrolet 250S should be on the list!! It was developed in the 70s as a variant of the older 3.8 that equipped heavy vehicles to be under the hood of the Chevrolet Opala, it made that car a legend in Brazil for its reliability and performance. With it, the Opala won many of the races it participated on, and earned its reputation as a V8 killer. It was a 4.1l straight 6 chain-driven ohv that even today, almost 30 years since the end of its production remais a very popular and desired engine for tunning, being nearly indestructible and very capable of gaining power. The most powerful of them is under the hood of a drag racing Opala that makes 1,500 hps and holds the record of every drag strip it raced on
My 3.8L V6 is indestructible and it’s definitely an engine I would vouch for!
I love the 3800s man
I'm glad he included the buick 3800 v6 i have one. And i can honestly say that IT is one of the best 6 cylinders ever created
I was looking for this comment! The 3.8 is one of the most awarded engines the US has ever produced.
So glad you put the Barra in here
maaaaate, I have an old AU with the single cam barra variant, (not the twin cam ,like in the terrirtory, ) and yes, they are a donk and a half for sure, freight trains of torque and towing power. Tows the boat like theres nothing behind it. MInes just run in at 300,000 kms :D
pity Ford Australia went broke. We will no longer see these beautiful motors in any new cars now.
@@davesboatingfishing The SOHC in the AU was called the Intech and in my opinion is the best motor they put in a falcon! I took mine to 360,000km before someone wrote it off for me but it's still parked up and used as a farm pig haha it triggered my love for inline 6s and I ended up replacing it with a Merc W140 with the M104 I6
I once owned a 1967 VE Valiant (Australia) with the slant-6 motor. They were super strong and gutsy. Legend has it that Chrysler replaced the slant sixes with the 245 and 265 hemis because they weren't making any money on parts for the 225s.
The AMC 232 and variants, (258, 4.0) were produce for 42 years, 1964-2006. I own 2 cars with 232s and I will take them any day over a V-8. They have plentry of power, and are light on the front end which makes the cars balanced, fun and very enjoyable to drive. And, they are bullet proof.
Glad you didn't miss the GM 3800!
Buick V6 not Chevrolet V6
Definitely do a part 2 for this video!! There’s so many more! There’s the 1GR and 2GR, the 4.3L Vortec V6 and 4.2L Vortec I6, the Subaru 3.0L H6...
The dodge slant 6 was one of the best engine ever developed.
It was for sure. People back in the day, said they called it the 225 because it would go 225 thousand miles. That and the dodge 318 were some of the only motors that I used to see make it over 100,000 miles without issues.
@@greybone777
There was a time when companies cared about customer loyalty and produced long-lasting products, then a younger generation began to take the reigns of control over these companies and wanted a faster return of profits, so they came up with a new plan, built-in or planned obsolescence, which they have down to a science that various products malfunction shortly after the warranty ends.
This comes from years and years of data on how long various materials hold up to the stresses of use. so that they can literally engineer a product that will need repair or replacement shortly after the warranty is up.
To build into products planned malfunction is dishonest, but what are we to do when all of them are doing it, there is no jumping ship to a competitor when the competitor is doing the same thing.

Had a 1971 van. 225 slant 6 paired with a 3 speed on the tree. Awesomeness, never an issue, ever!
Chrysler Australia's Hein six in 215 245 and 265 displacements were considered the best engines out of the three large family car players with Ford and GM Holden 1970 -1981. They succeeded the slant six in the Australian market Valiants.
The triple Weber version of the 265 used in the Aussie Charger two door fastback made it the world's quickest accelerating production six cylinder at the time.
Chrysler slant 6 is my vote. For 30 years there was a local cab company that only used slant 6 Motors in their cars. Hundreds of thousands of miles of Northern city conditions didn't even phase them. Visio has the thickest accent that I can easily understand. And the most interesting videos always very accurate and well-researched
Inline six, very smooth and simple to work on. There is so much space on each side of the engine.
I was a car mechanic thirty years ago and I will remember till my dying day an occasion when a Chrysler slant six came in to be serviced. Probably the smoothest idling engine I ever saw.
Yes , they where a pretty good old bangers , i had a couple cars with chrysler slant sixes AP5 and VC valiant models , australian built , the only gripe i had was , they seemed to go through manifold gaskets periodically for some reason , maybe something to do with the big ugly manifolds on them , other than that though , reliable old buggers .
Come to think of it i also had a cm valiant wagon with the 265 CI ELB, that was actually pretty car good too .
The only thing that spoiled all those cars was the crappy chrysler torsion bar suspension on the front , NVH just was not up to scratch compared to other brands imo .
Ford 300 cubic in truck engine one of the best ever
totally true. I had one. ran forever.
Sorry but my experience says otherwise. I'm steadfast at maintenance on all of my cars and trucks right down to the tire air pressure. I had the 300 in two different trucks Couldn't keep them from leaking oil. Fix one gasket and another would start leaking. And no I didn't have pressure in my crankcase. Plus I experienced major HP falloffs on both after about 50K. On one I couldn't replace the oil pan gasket unless I completely removed the engine. I had nothing but trouble with them.

My daily driver now is a 93 Jeep Grand Cherokee, 4.0 inline 6. It has 240,000 miles on it, (low actually for a 28 year old vehicle), and it runs just as good now as the day it was bought. Only engine work done was replacing the harmonic balancer. Freaky thing about this Jeep, the AC has never had any freon added and it still blows cold as ice!
Between my son and I we've had a lot of Jeep 4.0 ltr. 6cyl. engines and those things are torque monsters and live forever. One of the very best engines ever made.
300 6cyl Ford, excellent engines, 6 cyl and 7 main bearings, you can buy a steel timing gear set and it comes with instructions for an extra oil tap to run oil directly on the gears. The 225 slant 6 cyl Dodge- Plymouth was also tough.
I was waiting and then finally it was on the list at the very end, GM'S 3800. I've owned about 7 cars with that engine not all the original some were series 2 and series 3. Basically bulletproof with proper maintenance.
Missed opportunity having it be in envoys and cars like that a straight 6 in a Camaro would have been cool proper aftermarket and support would make these motors real threats
You are one of the very few channels where I watch every single video that gets posted. Great informative quality, pacing, and topics. Each time I watch one I know I'll be learning something new and that alone is worth it.
Keep up that good work man, and have a great New Year!
When I worked for Asplundh the chipper I ran had a Ford 300. That engine was no joke when I engaged the clutch and cranked the throttle up.
BIGBLOCK5022006 That reminds me, At a junkyard near me, the Car crusher they have is powered by a Chrysler 225 Slant 6, hes had it for years, runs like a top!
Anthony Ballmann That's the beautiful thing about the old school engines like the Chrysler Slant 6 and the Ford 300. You could beat the hell out of those engines and they come out smiling and say "Thank you, Sir! May I have some more?".
BIGBLOCK5022006 Yep, and on the rare occasion you somehow blew one up, you had an epic story to tell!
My 292 Chevy would still be runing if not for bad fuel pump .. Used to pull our 16' camper with it .
I love the AMC inline 6. I've had 3 Grand Cherokees with that engine. I had 2 97TSi and 1 03 Laredo. If it was cold or had been a few days, sometimes they would take a few seconds to start up and you had a nice old school highland starter sound lol. Perfectly balanced and rather hypnotic at 1800-2100 rpm traveling the open roads. Had one from 2000 to 2019 I'll have another 😉
Former boss of mine had a Ford van with a 300. Body and frame finally rusted so much it was starting to “inchworm” at 400,000 miles but the 300 was still going strong when it finally had to be retired
The one that was in our 1981 Chevy Malibu "Iraqi taxi" was amazing! The only part I can specifically remember my father changing on it was the starter. That thing was bulletproof, and still going strong when we eventually got rid of it to buy a van.
Ripplin you had a genuine Iraqi taxi?! Cool! Yeah, they had a carburetored version Of The GM 3.8 litre V6 (which is the last engine on this video 😉) which only made about 82kw, but was bulletproof. It's the same basic engine in my Holden Commodore Ute, that I drive to this day (I'm in Australia) but with fuel injection and a few other upgrades that almost doubled the power to 153kw. Damn good engine...
Man, I remember in Iraq how those were about the only American cars I'd see. The other taxis were Ladas and Toyotas and Nissan, but they loved them some Caprices!
@@banokles Besides that 3.8 (Buick 231 cu. in. design), Malibus, in Canada at least, could be had with a Chevrolet design 229 cu. in. V6, which also worked out to 3.8 litres, and gave occasion for confusion when getting parts. And mention of "Iraqi taxi" dredged up a faint and shaky recollection of (I don't think this is an urban legend) being told, around that time, that a number of new Malibus destined for Iraq or Iran were languishing on the dock in my eastern Canadian city, Saint John, New Brunswick, because of turmoil where they were to be sent. They weren't available to us, though, maybe not certified for our regulations. Also, though they were said to have A/C, I think, for some inexplicable reason, they didn't have heaters. That does sound like an urban legend, doesn't it?
My pap had an f150 from 86 with a 300 six in it and had 286000 miles and still ran great no issues I though that was great

The AMC inline straight 6 is by far the best!!
I agree even there v8's are just pretty darn tough
My dad bought a 63 rambler classic with the straight 6 new. Nothing flashy, but always reliable.
I have two AMCs with 232s and can say they are great engines. The V-8s were great as well, but the six was lighter on the front end and makes the car fun to drive.
The ford 300 was a madly popular hot rod engine, those things were beasts!! Inline 6s bigger than most of fords V8s when it first came out
An engine that deserves a mention here is the 2nd generation Chevy inline 6. The 194, 230, 250, and 292. They ran from 1962 (194) all the way to 2001 (292). They were put in just about everything from trucks to cars, forklifts, generators, boats, and more. Next to impossible to kill. I had a 1965 250 that went well into 500k miles before it wouldn’t make freeway speeds, but it could still putt around town.
Also, I think the Nissan VQ deserves a shoutout. I owned an Infiniti G35 for 13 years, put over 200k miles on it, and that motor never needed service once - unless you count the stupid cam position sensor (I don't). To give you an idea of how I ran this car, over the years I had four clutch jobs done on it.
Every other vq35de burns so much oil you don't even have to change it, Just keep topping it up.
@@fry.master Maybe I got lucky, but I don't remember ever having to top off the oil but once or twice.
@@chuckschillingvideos 100% luck my friend, those engines needed a hard break in to seat the rings so they didn't burn oil. Most cars didn't get that and burned oil the rest of their lives.
@@fry.master I gave my G35 6MT about thirty seconds of break in before the flogging began.
I've had a 1991 Jeep Cherokee Laredo, man that 4.0L straight 6 was so smooth and lovely, i'm missing it :(
I had one with one 270,000 miles on it with no engine problems. I gave it away.
the gm 4.3 is pretty reliable i've seen many with high miles on them
ChrisN85420 I'd honestly have it over the 3.8... we all know what the 3.8 likes to do when it finally gives up. BOOM.
Brydanyourday I've never seen one blow up and I've seen many of them go through some serious shut and all had high or higher miles
The 4.3l is indestructible as long as you keep up with oil changes got an 01 s10 blazer with 260xxx still runs like new.
Husspower enthusiast well, the boosted engines tend to kill themselves (grand prx gtp and such)
Brydanyourday not true. I've seen nodded one's abused to over 300k
Ahh, the Buick 3800. I have one of the later years of the engine - the Series II. So smooth and crazy reliable. Only 3 issues: the gaskets could be eaten away by Dexcool (GM specific coolant), the upper intake manifold can leak quite badly, and the recall that involved the valve covers leaking oil onto the exhaust manifold - which would catch fire. Apart from those three issues.....I love the engine.
I’ve always been a fan of the 300 I6. I had one for years without any problems. Even though I am not much of a ford fan, it’s a hard to beat engine
I had a '69 Plymouth beater "snow car" for winter use in Cleveland. I left Cleveland in 78 and decided to leave it there for nature to finish dissolving it. The only thing that had any value at that point was the slant six which a lot of the plugs would fire on a dry day and a '70 U-Haul trailer license plate. Some nice young man decided he wanted a project to learn about cars and he offered a $75.00 for it and I sold it . I bought it in '74 for $50.00 so all in all it was probably The first and only car I've owned that actually appreciated 25% over 4 years of daily use. The motor would buck like a jack hammer when the humidity was high and in the rain it would drown out the lifter clatter. As long as there was some oil / coolant mixture running through it's inners it would continue moving on it's own.
I've had the AMC 232 and the Dodge 225 slant. Great engines although the AMC was a bit underpowered for the AMC Ambassador. Just change the oil regularly.
Long live Ford's In-Line 6.
There were more than one.
@@fartsoundeffect5013 The Barra 4.0, and the others too.
@@fartsoundeffect5013 But you're biased, you are going for the one that sounds most like a fart! ;)
The Barra is much newer and better in every way, look it up and see what people do with them.
ruclips.net/video/I_szwWlh7jc/видео.html
One of my favorites was a 2.8-4.0 Litre Cologne motor. My 2.8 I modified a bit and got in a fair bit of trouble with.
Taught my son how to drive (sideways ) with the 4.0 in a B4000 with a 5spd.
The Chrysler slant size was unbelievably reliable. Back when I was a kid,
most other engines would be burning oil and having issues by 100K miles, but old slant
sixes in Dodges and Plymouths just seemed to have no problem going 150K miles
and running great. I wonder how well they would do today with modern synthetic oils.
(Oils back in the 60's were crap as compared to what we have today!) The old
Slant Six could be hopped up to perform like a V8. I remember a couple Dodge Darts
making several guys with V8's feel pretty silly in impromptu drags.
5.9 12 valve Cummins and AMC 4.0 are by far the most reliable when it comes to North American I6's.
Jonathan Morley do not forget about the ford 300.
Jonathan Morley I've heard stories of slant sixes running fine with huge holes in the block or with the crankcase full of water.
Jonathan Morley and stovebolt 6 it was cancelled for being reliable, the only we have upgraded (it’s only 5 years newer engine) is it was run without oil
I've got a 98 4.0l myself. I love it.
1998 Cherokee with 204,000 and a 1999 with 234,000. Both running terrific.
Back in the 60s, the Ford 300 cu in, would regularly last forever. I know one guy who had 600,000 miles and had never done anything but oil changes. With today's oils, it would easily go a million miles.
Australian Ford Falcon 4.0L straight six, million Kilometers quite regularly in Taxi's.
Aka the Barra he mentioned
4.1 not 4.0 the 4.0 is a v6.
@@republicansareoffendedeasi821good engine (4.1).Had one in a XD wagon.
@@markgillies1834 I have a 1978 Ford Granada it has three bad cylinders they're going to pull it out and replace it with a 300 straight 6 same year. I am going to save the money and rebuild the 250 I think the head is bad as well I think it's warped still starts and drives though.
John Sears the Barra ford 4.0L engine is a inline 6
Im so happy the 3800 v6 was #1 on this list. Even though a lot of the GM cars they were attached to were jalopies and could easily turn into rustbuckets, that block was built like a TANK. My dad had a '93 Chevy Lumina that had lost the hubcaps, had half of the exhaust system rusted away, half of the electronics deteriorated, and rust ALL over the body, but by the time he got rid of it in 2013, the odomoeter read ~325k miles and that motor was still purring like a kitten.
Yeah, ummmm NO. The biggest engine on the Lumina was the Chevy 60degree V6.1991-1994: 3.4 L (207 cu in) LQ1 V6. The 3.8 wasn't used until the 1998 model year. Nice try. And yes, I was an engineer at GM.
I had a GM 250 Inline 6 in my Nova & it was absolutely bulletproof, even with neglect from the previous owner
I had a pretty awesome ‘72 C10 with a 250 six and a later four-speed, it had over 200,000 miles, didn’t use a drop of oil, started instantly and got like 17-20 mpg, which is pretty impressive for an old truck with no overdrive. It could’ve been rebuilt at some point, it looked suspiciously clean, but they’re known to be pretty tough.
I have a 15 year old Chevy 4.3 L 90 degree..270.000 miles.. and it runs perfectly, no rebuild no BS I don't know how this engine was overlooked!
WOW one 15 yr old with 270 k there are motors out there that run for 30 yrs and over 1 million miles, get back to us when that chevy hits 1 million with no internal work done,never happen. 270 k is normal today, had that and more on many motors over the years. real longevity is 750k plus miles with out touching the internals of the engine. Then you join the elite of lasting motors. Kids today are impressed so easily. 270k LOL I got that and more on a 4 cylinder motorcycle that redlines at 11 grand and sees it often.
Bobby Williams reliable and durable they may be, they are a rough running in terms of balance.
joe must be talking kilometers. 270,000 miles on a motorcycle engine that regularly flirts with 11 grand?
yeah right.
@@RT22-pb2pp 1,000,000 miles yeah right!
Yay! The AMC six!
Volvo B30! Swedish iron! 💪🏻
The 6-cylinder Redblock! Did you know it lived on until 1984 in the C3 military trucks?
Think the Buick 3.8 V6 is worthy of mention here, damn good engines!! The Holden straight 6 engines were good too tough reliable long lasting!!
The older Merc 6 cylinder engines run Forever! The Jag XK engine design dates back to 1949 ( i could be wrong ) good engines quite easily tuned up but they were a heavy engine cast iron block!!
Went from a 275hp high compression NA all aluminum 2.3lima in my mustang 2.
That motor that was 20k is on a stand under a fire blanket. Just recently my new crate motor finally showed up to the house. Literally 2 days ago.
A merc 7liter sb4 is what is in the makings for the little mustang 2.
Anyone who doesn’t understand what that is. Mercury marine. Took there chevy big block, short block motor they use in all there high performance inboard motors. Instead of 9liters like most. Kept it at 7. Throw there own in house DOHC heads on it. Such an amazing motor merc has been making. It’s been offered as a crate motor for quite a few years now. Sounds so amazing !!!
I am glad you included the Chrysler Slant-Six. I owned a couple of different cars with that engine, and it was, indeed, bulletproof.
The AU I6 4L barra engine last for a while. 600,000km then retired in the taxi company
Bandit 3076 I didn't think the AU got the barra, wasn't it the BA that first had them? See plenty of Barra's for sale with over 800,000k's crazy engine
The AU had the SOHC Intech, that was the truly simple bulletproof engine, I still own mine. The DOHC Barra was introduced in the BA. Almost identical block and bottom end but the addition of a lot of electronics and variable cam/valve timing and an extra cam shaft made it much less resilient to abuse! Still get 1,000,000km out of one with half decent service intervals though...
Best Barra was the FG XR6 Turbo 4L - stick some stronger valve-springs in it, add a bigger turbo and it will take you to the moon in seconds
Sean Kretschmann I retired an FG after 7 years service as a Sydney cab with 982k on the clock. Sadly I can’t see the Camry hybrid that replaced it going the distance.
Unfortunately nearly all manufacturers are moving away from inline six engines and going to V6, which is a shame because historically inline six's have been the most reliable and smooth type of engine.
Lets just all agree that an inline six is the best engine layout .
alec mathews maybe after boxer 6 and v12/v10
Yeah I can't think of a single inline-6 ever that has had major problems, except maybe the Toyota 7M
alec mathews 60• v6 lfx best motor
How many v6 engines have lasted as long as the inline6 ? None of them . The inline has the smoothest power as compared to the v6 with the least amount of vibration .
V8 or nothin"!
300 ci ford and 258 ci amc was two great long lasting engines for sure
In nerd-speak, an inline 6 is inherently balanced in that (if you perform the calculations) the reciprocating masses have no 1st order or 2nd order vibrations (or 3rd order, or 4th...). Obviously, a V12 falls in this category, too.
Providing that it is a 60 degree V12. Many are odd angles, like 67 degrees or something.
Good to see the “Barra” made the list
Right? I'm pumped we're finally getting them in the states. Also if gm would of advanced the 3800 like ford did their 3. Ecoboost gm would be taking it in.
3.8 Buick fireball is a bad ass motor it's my personal favorite and you didn't talk about it getting a turbo or the supercharger. Grand national or pontiac GTP or it smaller brother the 3.3 which also got a turbo. A lot of performance and military history in this motor. My camaro has one with 5 speed gearbox. My monte Carlo did too and my cousin had a 1992 oldsmobile toronado trofeo with a supercharged 3.8 it was a beast all the way to 370.000 miles.
I've seen some Grand National-s and '89 Trans Am's with seriously high mileage in spite of power adders and hard use.
my dads 97 buick lesaber was a 3.8...... 256,000 miles
runs great
kain hall just got rid of an 03 Bonneville with 300k on it. I didn’t get rid of it because of the motor I got rid of because of the chassis electrics. I ended up with a 99 silverado with a 4.3 in it.
I have a 81 Pontiac grand lemans with the fireball v6 in it. Sat for 15 years in an alley, started right up with new battery & fresh fluids lol
I like the 3800 V6 as well have a 03 LeSabre it only has 115kmiles on it but plan on keeping it till it has well over 200k miles and see noreason it wont make it with no major rebuild
Jaguars AJ16 engine seen in the x300 series XJ is the most reliable jaguar engine produced, even the electronics aren't plagued with jaguars "cost cutting" methods because it was produced under Ford, with the possibility of it being used as a diesel and petrol block!
For more information on this engine, look to AJ6 engineering, they deal exclusively in Jaguar engines, and they are the last word in Jaguar Tuning www.jagweb.com/aj6eng/
Producing a block that could go diesel or petrol, sounds like a cost cutting measure to me, though. Besides that, I am surprised to see Jaguar as a reliable engine maker here. I get a bit suspicious about the quality of an engine when there is a well-known company dealing only with engines of one make.
Phil Atkins from 90 up they had good electrical. I love my 90 AJ6. Very little difference between the later aj6 and the aj16
5 wins at le Mans 1000's of wins world wide and used for over 30 years says the XK motor is a legend
I had a Ford 1/2 ton pick up with that 300 6 , it just kept going and going 430,000 miles and the engine was never opened up . Only thing wrong with that truck was the steering gear bax had to be replace ( $17.50 ) from Pick-a-Part . Sold the truck and the engine was taken out to tun a portable sawmill. I averaged 28 mile to the gallon, Imperial gallon . Not to shabby for an old pick up
I love my AMC 232, running perfect and quiet for 40 years.
The chevrolet 230-292 inline 6 engines were very long lasting.
Yes sir
My dad had a 194 Chevy when I was a kid.
glad to see AMC love here.
Holy hell, no one is gonna mention the EG33 or EZ30?? I've seen tons past 300k miles.
theres a guy on youtube transplanting this an EG33 into his 16 sti.
glad to see the amc / jeep motor on the list. 20+ jeeps owned by my family over the last 25 or so years and i cant remember a single major engine repair. just maintnance and the occasional bolt on like waterpump or starter. a few have seen 300k+ befor being sold only to see them years later still trodding on.
#1: Basically every 6cl diesel engine made by Cummins, John Deere, Cat or Deutz
Edit: Oh, and Detroit
#2: In keeping with our Made In America narrative, don't forget the AMC I6. Also a really great engine that will take care of you as long as you take care of it.
@@Jethu262 Wasn't the 5.9l B-series everyone keeps going on about actually a re-purposed British tractor engine?
and toyotas straight 6 diesel, far better than all of what you just listed
And any international harvester, they knew what they where doing.
What about the 4.0l jeep i6. That thing will tick after the last man on earth dies. I know, cause I have one, a 95 jeep Cherokee. Only thing olive ever do to the engine is change oil
Diamond Eyes true, I got mine from a lady who couldn't drive stick, so the clutch does nothing after 1st gear,
its the amc 6 in the video
The 4.2L evolved into the 4.0L the video kinda hinted at that when he said it was made into the 21st century. I believe the last year for the 4.0L was 2006
The 4.0 is basically a revised 4.2 AMC so it is there........sort of.
How do you know that it will still tick after all men are gone get real
The ford 300 I-6 was a great engine, I knew alot of delivery van owners, 850,000miles with just fuel pumps and starters replaced. The old UPS brown trucks, some were 25yr old,you don't see them much any more,UPS would scrape them(they would not sell their brown vans), also the chevy 292 I-6 was a great engine(UPS used them also). I agree with your followers that the AMC-Jeep 4.0 wasn't mentioned, that it also was a great engine.
Once Ford put port EFI on the 4.9s, they were unstoppable. When I worked for GoodYear, we had a fleet of mid 90s E250 extended wheel base vans which we used for delivery vehicles all around Chicagoland. We would scrap the vans due to body rot at around 3-400k, but never once changed an engine. They were gutless and didn't like to rev, but they never broke. When Ford switched to the 4.2 V6, we had nothing but problems. Long live the cast iron king!
Ford Australia had issues with the Ford 300. Not reliability, but the fact that they were so heavy on fuel. They took their own 6 cylinder, developed from the 170 "super pursuit" 6 cylinder first seen in the first US Falcons. Over time, they were bored, stroked, given fuel injection, double overhead cams, cross flow heads and turbochargers. They developed a specific version for the F-series. Known to most as the 250 truck engine, it had a high compression, cross flow head, 250 cubic inch capacity, and electronic ignition. I used to work at a remote roadhouse, and the tow truck was an F350 with one of these. It had diesel-like pulling power, and was as reliable as sunrise.
Edward M Alves It was, the 4.0 Jeep 6 is an evolution of the AMC inline 6 engine that has been around since 1964.
Yes I know that; that is why I called it the AMC-Jeep in my 1st comment.
I'd love to have a DOHC head and manifolds with EFI for a 250 block. I have a little project in mind.
Shoutout for the.. iron Duke.. the ford straight six 300 With a single barrel carburetor the best motor Ford ever made I had a Ford F-150 the shackles rusted off the rubber between the frame and the body disintegrated to nothing truck set sideways rust all the way through the chrome bumpers rust holes all over The body and frame doors wouldn't shut properly tailgate wouldn't shut properly but it still ran perfect till the very day I had to scrap it.
My friend in Australia had an XD Ford Falcon as a taxi ..it had 1.3million kilometres on it when a truck ran a light and wrote it off .. original block, on its second cylinder head and second pair of front disc brakes..it ran on LPG .. 4.1Litre ohv straight six !! Beat that !!
I have an all rebuilt 300 in storage (don't have anything to drop it in) and the venerable 4.0 in my jeep tj.
For something to drop the 300 in, I'm thinking...Fiesta!
Couldn't help but notice the BMW's blinker stereotype at 5:35 😂
Cant use the turn signals if you dont have any.
Honestly the 3.5 ford v6 is decent
I drove my grandpa's 1 owner , all original 71 Ford F100 SB 4x4 with it's 300 I6 for 18 years 6 days per week and 78 miles 1 way to work. The truck had 351,678 miles on it when 1 began restoring it . Not once has the truck ever broke down since brand new. It's always had preventative maintenance and service. But it is a bit more truck then it ever was now. The 300 I 6 still ran good but definitely lacked power. Adding a 600 Cfm 4 barrel carb , bigger intake, a ported 240 I6 head, comp cams performance cam, roller rocker arms, bigger valves header and blow through turbo charging and 9 lbs of boost to the 300 makes it unbelievably awesome . I could go more boost reliably but it is plenty powerful with the 9 lbs and other mods
the straight six delivers...period. best engine design, super torque/horsepower ratio....never stops running.....
This needs MOAR Nissan L-series love..
