Its funny im rebuilding a slant that had pretty much no cross hatching rust pitting in 2 cylinders enough slop in the chain that it slid right off and tons of sludge in the pan and it still was running when pulled. You have to be a special type of stupid to kill a slant and have it stay dead.

When I was 16 I got a 75 duster with a slant 6. Wanted to swap but dad said wait until something goes wrong with this. I beat thr hell out of that thing including running it low on oil. A year and a half later, I pulled thr slant 6, sold it and bought a 360 magnum. The car that got the abused slant 6 ran for years afterwards. They were great engines.

The Ford 300 inline 6 and the 7.3 Powerstroke need a spot on the list of indestructible engines

[@joeg2865]

The 300 is well known for cracking the head

[@RockandrollNegro]

@@joeg2865 The 200/250/300 Ford Thriftpower 6 family was indeed known for cracked heads, due to the exhaust port overheating from being placed directly under the carburetor. If you never let the engine overheat or run low on oil, it was usually never an issue, but all it takes is for your waterpump to go out on the highway one day and suddenly you have a cracked head. Thankfully, they were pretty durable in every other regard, so even having a cracked cylinder head or wall, you could still usually get another 100k to 200k miles on the engine before you needed a rebuild. I always put the Ford Thriftpowers below the Chrysler Slant 6, Jeep 4.0 and Chevy TurboThrift inline sixes, in terms of reliability, simply because of the head issues, but I personally never had a problem with them. I had a 200ci Ford engine get a half a million miles in a Granada with absolutely zero issues. It was probably the most reliable vehicle I ever owned.

Does OK in Super Duty, if regular cab and 2wd. 4x4 and crew cab can add too much weight to HD SD chassis; depends on use. My SD work truck has emissions sticker allowing 2 valve 5.4, even though it is a 2005 model.

In 1997 I went to work at a Lexus dealership in Mission Viejo, California. I didn't know much about Lexus but I soon found out I was selling the best cars on the market. One of the first things I did was test drive 2 different 1990 LS400s. They both has 275,000 miles on them, I was astounded, they drove like a new car, there were no rattles, very quiet, all electronics worked great. I've owned 4 different Lexus since then. Here's a tip on buying vehicles, buy Japanese. I've found the Japanese build their vehicles to run 300,00 miles at least. Always run a carfax, or something similar. Always look at the car and the price online before going to the dealership. If your buying a new car definitely shop online. I tell people get on the phone, tell this dealership representative, I'm buying a car today and I'm calling all whatever brand say ,Toyota"dealerships and whoever gives me the best price, that is who I'm buying from, that way you don't have to have a salesman, then a manager come in and try to put pressure on you to buy there.

I have been a mechanic for over. 50 years, owned almost every engine on your list, and I have worked on all of them. My vote gives to the Chevy small block. You can buy any part for that engine cheap, including the block in cast iron or aluminum. Same for the heads. Cranks are available in forged or cast. Any type of rod you want. Made from 1955 to 2001, over 1,000,000 made almost every year. My favorite is the 5.7 Vortec with factory roller cam and Vortec heads. Anybody know how many races the small block has won? Maybe it you turned your hat around?

I had a neighbor in Puerto Rico that owned a Celica from the 70s with a 22R, he ran the car with no oil for about 2hr. And he made it home. The engine seized. The following weekend my uncle replaced the pan, put Castrol, hand spun the engine and told our neighbor to crank it. It started like nothing ever happened and he drove it until the early 2000s and parked it because the floor rotted. The car still in his Yard today. 😂

I can also relate. I have a 22R that our saleman ran out of oil, it broke #2 and #3 rods and put a hole in each side of the block as big as my fist. The truck sat in a open field in Ark for 3 years with an exposed crank, waiting on our salvage yard customer to get one of the up north trucks that the body gets rusted outs engine to replace it. After 3 years of waiting right before replacing the engine, I decided to see if it would start. Battery charger and a couple shots of ether in the carburetor and it kicked right off and ran. I ran for about 15 seconds than shut it off for my safety as I could see the rods hitting the holes in the block.

The iron Duke's reliability is still the reason we see 30+ year old mail trucks still chugging around our suburbs. Yes, the 2.5 iron Duke was the only engine available for the 200,000 Grumman LLV mail trucks, which were built on a short wheelbase S10 chassis with a blazer rear end

[@johneckert1365]

S-10 and Blazers share the same rear-end. The 4WD rear-end is wider to compensate for the negative off-set rims that the IFS 4X4 front suspension required. What GM did on the LLV chassis was use 2wd front suspension but used the 4wd rear-end with the 2wd rims. That's why the rear wheels track wider on the back of them.

[@rachelbarron5642]

Well duh they arent put thru much stress, its the same with old ass 30+ year old ice cream econolines, and Chevy vans. The ones in my hood been riding on the same dilapidated suspension for the past twenty years

[@johneckert1365]

@rachelbarron5642 The transmissions go through hell on those from all the stop & go driving. GM produced those chassis with a TH700R4 (with the small bellhousing pattern) which was a poor choice. I bet nobody teaches the drivers to use 3rd gear rather than D. GM should've produced a small bellhousing TH400 for those mail trucks, those transmissions would've lasted FOREVER then.

[@malcomreynolds4103]

@@johneckert1365 Putting them in 3rd is irelevent, overdrive would only come into play at highway speeds at which point the 700r4 would operate MUCH cooler than a th400. THe 700R4 also has better gear ratios for stop and go than the th400

[@johneckert1365]

@malcomreynolds4103 I will agree that a TH700R4 has lower gear ratio in 1st-2nd gear than a TH400, but that's it. Everything else in your comment is nonsense though. TH700R4 shifts into Overdrive around 40 mph, not "highway speeds" of course then at 40 the Iron Puke can't handle overdrive so it shifts back into 3rd. Then back into Overdrive, and keeps repeating. 3rd gear on both transmissions is "direct". Direct is basically just connecting the input shaft to the output shaft, all other planetary gear sets are just along for the ride, thus reducing friction, heat, and parasitic energy loss. Direct is the BEST gear to promote transmission longevity and prevent wasted energy, both in Automatic & Manual transmissions. Ask an oval track racer why they use Direct gear sometime! In normal mail route driving, the TH700R4 WILL NOT run cooler than a TH400. Yes, the TH700R4 uses a lock-up torque converter, which will create less heat when in lock-up mode. Well when a TH700R4 is in the "Overdrive" or 4th gear selection, the converter doesn't lock up until after the trans has shifted into 4th gear and is cruising at a higher speed with light throttle pressure. How often is that happening in these mail carriers? Not very..... Now if the gear selector is in the "Drive" or 3rd gear position, then the torque converter will lock up in 3rd or "Direct" gear, giving a true direct drive connection from the engine to the driveshaft. This is the most efficient mode for the transmission, it's creating the least amount of friction, which in turn is creating less heat. It's also losing the least amount of energy through parasitic loss. I don't care if you disagree with me, it's a FACT that all overdrive transmissions would benefit from being driven in thier "Direct" gear while they are driving at less than highway speeds and for short distances. That is why these LLV drivers should be using the 3rd gear selection rather than 4th. Even everyday drivers in thier normal vehicles would benefit from this in city driving. Unless they were building these LLV mail route carriers for long distance highway driving (which we know they were not), the TH700R4 was a foolish choice for it's transmission. That is why the S-10 bellhousing TH700R4 was Jasper's most frequently remanufactured transmissions for 20+ years. The TH400, which was still being produced at the time the LLV chassis was designed by GM, would've been a MUCH better choice. It wouldn't have been any more fuel efficient, but it's longevity would've saved the USPS millions if not tens of millions of dollars. Not to mention that a TH400 was cheaper for GM to produce vs a TH700R4. Overdrive is a bit of a sham. Yes, I get it, it lowers engine RPM and saves some fuel. As far a transmission wear and energy loss goes, overdrive is wasteful. Think about it. We're taking our engine RPM, then by using gears (thus creating friction) we are increasing that RPM in the transmission, just to send it to the rear axle to slow the RPM back down. Say that to yourself slowly. We're speeding it up just to slow it back down 🤔. A better solution to achieve the desired final ratio (the ratio between the engine RPM vs wheel RPM) would be to have a higher (numerically lower) gear ratio in the rear axle, then give us a transmission with more lower gears to compensate for that. That would be more efficient than this "overdrive" waste we've had for over half a century. I don't expect many folks to agree with me, but it IS a fact, that the strongest and most efficient gear in a transmission is DIRECT. Have a good day.

You forgot possibly the most indestructible of all. The old Chrysler Corporation slant 6 G. The engine gained a reputation for reliability and durability. The basic design is rigid and sturdy, in part because the engine was designed to be made of either iron or aluminum. An aluminum block was produced in 1961-1963, but most blocks were made of iron. The block is of a deep-skirt design, with the crankshaft axis well above the oil pan rails for structural rigidity. Although only four main bearings are used, they are of the same dimensions as those in the 2G (1964-1971) Hemi, and fewer mains results in a crankshaft better able to withstand the effects of torque. Efficient cooling and lubrication systems, a favorable ratio of connecting rod length to stroke, and a forged steel crankshaft (on engines made through mid-1976) all contributed to the engine's strength and durability.

A list about the most reliable engines is simply not complete without the 1.9 TDi

[@estoneback5022]

There is one engine that would belong on your list, the Dodge slant six.

[@RT22-pb2pp]

He is right on older domestic inline 6 motors I will agree with that on domestic vehicles. Low power but last

[@bigj200016]

My first car was a 72 AMC Hornet with the 232. Simple and you just couldn’t kill it no matter how hard I tried when learning to drive… and it was a stick on top of that

[@jimsix9929]

when I was younger I bought an f100 pickup with a 300 six, I am a mechanic and really wanted a truck with a v8 but this thing looked great, I thought what a great project, get some power out of this thing, I milled and ported the head, installed an exhaust header from clifford, a 2 barrel holly carb, changed the cam and advanced it 4 degrees, it ran a lot better but still a good 302 would have more power, it did pull a trailer like it was not even there

[@tonyunderwood9678]

I agree with the many user comments regarding the Volvo red block, Mopar slant-6, and some of the VW inline 4 cyl products... some others like the Ford Kent (another over-engineered under-stressed design) also come to mind. Then, if you want astonishing durability, albeit off-topic, you could look at some aero engines like the 12 cyl. Allison V1710, several of which early-on were endurance tested to the limit on test benches at full throttle flat out takeoff power, running continuously on a dynometer for days (150 hours) without stopping. Afterwards, the engines were torn down and inspected and they all still met factory specs and tolerances showing no appreciable wear. How many auto engines could endure that sort of abuse and not only still run but run well?

[@spunas1]

The 300 or 4.9 str. 6 Ford I can attest to, my 2nd most abused motor I owned however was the dodge 318. Almost, if not as indestructible.

[@detonator2112]

No Volvo engines on the list although they have the world record of cars with most mileages? Crazy. Old Mercedes diesel engines were amazingly durable too.

[@rapom61393]

Ford modular? OM617? VW ALH? Red block? While this list is very spot on ( love seeing the 3800) I feel there are quite a few that also deserve some love.

[@scorestore6345]

1.9TDI... Europeans will understand it

[@swatcat7928]

ALH

[@saleemcarr9501]

ALH

While the 225 slant 6 really wasn't the leaning tower of power is was indestructible for the most part. I did meet one person kill 2 of them but I found out when he started the car he immediately revved the heck out of it and then he would rev it just before he turned it off...not sure why but after many miles that sure would do it. Meanwhile most people like my Dad performed oil changes regularly had 187k on ours after teenagers put over redline quite a few times and still running pretty much as new, when he traded it in for a much worse truck. Some of the old commercials for oil additives show a slant 6 running on no oil for a very long time.

[@johneckert1365]

Chryslers slant 6 was indeed tougher than the AMC 6 cyls.

[@TheGulfcaptain]

Don't forget the Dodge "slant six" used in the Plymouth Duster and other 70's Mopar vehicles. Another nearly indestructible engine.

[@malcolmh5736]

As a kid, we had a Plymouth Volaré slant 6, 225 with manual 3 speed + OD (4th gear) hurst shifter on the floor, all stock. That engine was amazingly reliable and had longevity. That car wound up being more reliable than any other car I had, including my 1984 Toyota Corolla. I can hear the sound of the Volaré ignition in my head even now decades later.

[@stevedeleon8775]

The Legendary straight 6 cylinder Ford 300...they are Bullet Proof & Indestructible..
