Ford motors.
That company beat Ferrari (Lemans)with a heavier and slower car (GT40), and with old-fashioned non-overhead cam technology from passenger car/truck engines. How? Their engines that did not break (as often) as their competitors (including Porsche).
Ford makes the most reliable engines. Perhaps their best: model T, straight 6 (1960s), flathead v-8, and 351 windsor. The 260/289 v-8 deserves honourable mention as well.
Ford pretty much owns the race record books. The 1964 Thunderbolt (a clunky Fairlane) still considered the fastest production car of all time.
I couldn't stop replacing the cylinder head gaskets in my 93 Ford Taurus back in the day.

Even though Ford is making some very nice looking cars today and even some new models that are to come out look great, I just can't get myself to walk into a Ford dealership. Once burned, never return I guess.

Let's not talk about Chrysler, I would need a full page for that fiasco.

I too had a 3.1 V6 in my 2001 Malibu and I had no problems with it at all and I drove it 7 years straight. But the most reliable car in my family is my grandmother's 1970 Plymouth Swinger(same as a dodge dart) with the Slant 6 225CID.

It has been continuously driven for 40 YEARS and has NEVER had a breakdown!!! And I mean it has never failed to start or stopped running, the only thing ever done to it were a rebuild of the carb, new alternator and a recore of the radiator, that is it!!!

And the incredible thing is that after you turn it on you really find it difficult to hear it or feel it running, meaning it is so quiet and smooth that it is quieter then any other luxury car I have ever owned and I have owned them all including a Rolls Royce Silver Shadow that had only 3k miles when purchased.

This Plymouth Swinger simply defies belief, really the thing is 40 years old and the engine, tranny and rear end has never been taken apart, just fluids changed regularly. The Swinger doesn't even leak oil?? I mean even the valve gaskets are original and it has 452000 mile, oh and did I mention the original interior had no rips, really strong vinyl that is garage kept.

Are you freaking kidding me, 40 year old seals that still hold, what did those guys do in 1970 when they built this thing?

So we will never be getting rid of this car as FOUR generations have driven it and FIVE generations have ridden in it.

THE MOST RELIABLE ENGINE EVER IS THE DODGE/PLYMOUTH/CHRYSLER 226CID SLANT SIX, period! End of discussion, thank you all for contributing but there is not better engine, you could put it in a Rolls and it would be quieter and with a four barrel carb more luxurious then their 6.7 liter V-8.(1963 Aluminum slant six not include, they tended to explode)

alot of engines can be reliable as long as there maintained. really like the jeeps 4.o inline 6....the high output one has 250 lbs of tourqe and almost 250 horse power. these are rated up to 300 miles and go far oast that...also the 4.3 chevy motor v6 is extremly tough...my vote goes to the jeeps 4.o

My vote goes to the jeep 4.0, although I'm surprised nobody mentioned the ej22 from the 1st gen subaru legacy, also BMW's I6's are awesome engines.

Mine goes to any and all CATERPILLAR diesel engines.
GM small blocks are great as well.
The 3.8 never, ever stops.
The Vortec are tough as nails

i have a 1990 ford f150 with the 300I6 and a granny low 4spd. i got the truck with 320k miles from my grandpa and he changed the oil every 2500 miles and took good care of it. he pulled a feed trailer every day with that thing and i pull a trailer at least 4 days a week and it has over 390k miles and doesnt burn a drop of oil. the only thing i have had to replace is the rear main seal the water pump and the valve cover seal and the u joints. i think hands down the 300I6 is the best motor ever made. it runs forever and can almost pull anything. if i cant pull it in high range i just put it in low and try and get the tires to hook up. this motor is just an absolute monster.

I believe most honda and toyota engines are very reliable but im going to have to go with the others on this GMs 3.8 V6 is a very, very, STRONG motor, and for being American made well thats just great. Screw the Japs buy GM, FORD, OR DODGE products keep the money here in the US. Well people say toyotas arebuilt here in America and they create jobs what people don't think about is the fact that when you buy a new jap car a lot of that money goes straight to japan.

they are ok. They are easy to work on. But not extremely reliable. They are basically just a cast iron ls1 with different heads

The jeep straight six motors are extremly reliable. I have one now with 250,000 miles on it and it still runs like brand new and I've never done anything to it I just change the oil. And I've done a tune up. And that's it. I've seen them with 400,000 - 500,000 miles before still running great

The Chevy 350CID small-block V8s. Have a 1985 Chevy C10 pickup with over 204,000 miles on it with the original 350CID engine in it. Never been rebuilt or refurbished. Just how it was when it came out of the Flint plant in Michigan. And it still is running strong.
