      My uncle had one it had one million kms on it no joke seriously. Ford wanted to give him a new truck for free and take back his old one because they wanted to see how it was possible to last so long. It was a 1980 Ford F-150 he bought it new he died in 2010 the truck is still around.. I should add the truck is the six cylinder engine.

    We had a 71 dodge dart, w/225 slant 6. My sister drove it over 100 miles without most of the oil as the oil pan had a leak in it. We replaced the oil pan and gasket and it ran for almost 200,000 miles more before my dad sold it. Unbelievable durable and reliable engine. Super simple design and super easy to maintain. I miss that in today's engine compartments.

      So you had a reliable one - So what?
      I used to fix them for a living and they have no right being on this list.
      As a qualified mechanic you don't see what we do. I really don't understand where the rumors of legendary Slant reliability come from? It must be an urban myth or something.
      They are in there with the most unreliable inline six engines, not the most reliable.
      A reliable I6 that was omitted was the Toyota 2F so this list is anecdotal opinions compiled and presented as fact in my view.
      Some of the engines in this vid are very reliable, just not the Slant. I would never ever trust one of those engines and I'm a Mopar nut. I know it's not an inline 6 but a 318 is so vastly more reliable than a Slant it's ridiculous.

I recall a charger for AAA and other batteries had great reviews. When I tried to buy it, none to be found. I learned the company had replaced it with another model. The new one had TERRIBLE reviews! A woodworking magazine did a review of an adjustable support to be used with table saws and such. I went Home Depot to get one, and they did not have it, and had me order it from the company that made it.

    I once owned a '67 Chevy C-10 panel wagon that had the L6 250 w/manual 3 speed. Bought it for $500 in 1979 at a small used car lot. Was in great condition with a Green Rust-Oleum paint job and the entire rear compartment covered with a quality indoor-outdoor nylon carpeting. Had 34,000 on the OD so was assumed it had 134K. Got it cheap because nobody could shift it into any gear. I looked at the 3 on the tree linkage inside the engine compartment to to find wear had worn slots into the shift rods due to a lack of lubrication. I bought it then returned with a tub of axle grease. I slathered that onto the linkage and learned how to finesse it into the gears before driving it home. Met the original owner a few months later to be told that the engine had 234,000 miles of use, a new clutch assembly and u-joints. It was a heavy 1/2 ton with 8 lug wheels. It would get 24 mpg loaded down when doing 55 to 65 mph. I put another 65,000 on the OD before it got totaled in a head-on collision. I currently drive an '88 Chevy G30 work van with 300,000 miles on the original 5.7L and TH400. I wouldn't mind setting a rebuilt 292 L6 with a rebuilt 700R4 and different ring & pinion in it to get better gas mileage and easier access to the engine. Been driving the van since 1994 so have become attached to it.

    The AMC six in older variants, 199, 232 and 258 cid engines along with the chrysler slant 6 were used in taxis in the sixties and racked up over 1,000,000 miles without a major engine component failure. We are not talking about water pumps and things like alternators and starters. The major cause of failure in cause back then was not engines, but bodies, transmissions and frames. Most engines back then long outlived the cars they were installed in.

I find it interesting that we all managed to get around just fine with 200 hp engines and even 300 hp truck engines. What is more important is torque, In line 6 engines had long strokes that devloped lots of torque at low RPM's When they were carberated they were dirty. but with port injestion or even direct injection they could have been cleaned up and even could have been made more powerful. These changes coupled to an overdrive trans would have made them winners. What killed them was the sylist wanted lower hood hieghts and sleeker lines. To bad though look at the shoes boxes coming out these days. Also cast iron engines that run slower just last longer , and god knows we can't have that.

    Yup! (2) 225 slant sixes in a 1979 ex-phone company short bed Dodge pickup and a 1982 long bed as well. Best inline 6 on earth! The 1979 had legit 500,000 miles on it and it ran great! Also had a 1976 Chevy square body with a 250 inline 6, fantastic engine as well!! I love inline 6’s. Another excellent inline 6 is the 6-71 2 stroke Detroit diesel, probably the best engine in world history along with ALL Detroits, Cleveland diesels, and EMD’s regardless of layout! These engines built built this country and won WW2. We had Fords with 300 sixes too. Good motors, and I ain’t even a “Ferd” guy!

    I learned to drive on my parents' 1968 AMC Rebel with the smooth 232 c.i. six and automatic. The car passed through the family and eventually disintegrated many years later, but that engine was still going strong. As a side note, I was seriously disappointed when they passed on the 290 V8 for the six, but history proved it to be a wise move. Funny how so many of your parents decisions and actions become better over time. 🤔😅

    Having grown up in this era, it was expected that you bought a straight 6 above all else. V-8's were for the ones that wanted to fool around on the road, but for pure reliability, the 6 was it. Some of us wouldn't even think of having anything else. You bought it, maintained it and there was never a thought of it wearing out. Then front drive came along and fear gripped us because we saw the straight 6 on the road to disappear. To say we were depressed would be an understatement. I despise everything new that's out there and SO wish the straight 6 was back for common use.

    I had a 240 cid that ran for 27 yrs. Not one ounce of trouble. It went 169,000 miles. I was very careful to filter & oil change b4 the 3,000 mile limit...every time. The motor was blowing oil out the exhaust. I had the valve stems changed, hoping that was why.
    I had the $, so I had a 300 put in my '65 F100. Real strong. I should mention...I put a set of efi exh, mnflds on the 240 one yr b4 I retired it. WOW ! the two mufflers and short runs that turned b4 the pass rear tire...it was a whole new motor.
    The 300 has the efi's on it too. Don't need a V8 with this set up.
    I am using Shell Rotella 15W40 T4 oil now in the 300. I was advised to use this by a west coast nitro drag racer. The motor does well with it.

      Their mistake in the U.S. was to not replace it with the Hemi six they designed but passed off to Chrysler Australia. From 1970 we dropped the 225 for the 245 Hemi, followed by a 215 and 265ci in 1971. 7 main bearings, 12 port, huge valves. More power, more economy and at the same time. Easier to work on than the slant to boot.

    One of the engines you missed is the Dodge Plymouth Chrysler inline flat head 6 cylinder. One of the first engines to run full oil pressure to all componants inside the engine. Built in various sizes from 1938 to 1959 for cars and on up to 1972 in trucks and industrial applications. They were not powerful but they were torque monsters of their day do to their long stroke and slow running longevity. I have one of these engines in a 1951 dodge mayfair 2 door hard top 218 cid Exclusive to Canada It fired right up after a 25 year sleep and had 40 psi of oil pressure. It now is ready to be on the road this coming summer in its restored original car. This engine did not need to be opened up, it does not burn oil and runs smooth.

    Inline 6 engines originated as tractor engines, and they lasted forever. We've got tractors from the 40's and 50's that are still going strong today, and they aren't that difficult to work on when something does go wrong.
    My dad has an old Co-Op E5 that he loves. It blew a piston a few years ago, and we were able to drop the oil pan, remove the head, and disconnect the connecting rod and pulled the piston out in just a couple hours while leaving the engine in the tractor. He pulled another piston out of another engine he had, re-ringed it and we put it back in a few days later, reinstalled the pan and head, and it fired up.There was a slight antifreeze seepage in the head gasket, so we pulled the head back off and replaced the head gasket. It has been running strong since. It's one of the farm's loader tractors, so it sees it's share of work every year, though not as much now since dad retired and rented the farm out. But it's still his favorite loader tractor. My personal favorite is our Oliver 880, also an inline 6. That's been my go-to loader tractor for years.

  • @bladerunner5810

    The common item mentioned in this video, the one that is key to longevity, is a cast iron block. They are the closed deck design. Open deck aluminum blocks are the bane of modern, high efficiency engines. No one has mastered the art of making an ICE out of aluminum and making it live for a long, long time. Aluminum has a high coefficient of expansion and that has always and forever will be the #1 enemy of longevity......IMO. Engines that use cast iron blocks and aluminum heads require a lot of attention to the cooling system as well as frequent oil changes. I ran Nissan/Datsun SOHC L-series engines for decades but I had to torque the heads and lash the valves every year (10k to 12K miles). Bulletproof. Transmissions were as well. Nissans became relatively unreliable pieces of sh*t when the engine designs were changed to open deck aluminum blocks....IMO.
