I would like to start by throwing out two that I can't decide which is more reliable First the 1UZFE-4.0 V8 found in the Lexus LS-400 models, Second would have to be the famous 22re 4cyl. I would tend to lean more towards the 1UZFE just because I have seen these engines personally with upwards of 500,000 miles with no major rebuilds on a consistent basis.

Now it's your turn tell me what you think is the most reliable Engine ever made whether it's was or is for a car, heavy truck or piece of equipment.

I have no idea as to what is the absolute "best," but can throw out a few suggestions.

How about a CAT 3406?

And I'll also nominate the John Deere two cylinder diesels.

Not sure why you'd post this thread in "Dozers" and then start out talking about a Lexus engine, I moved it to "General Industry Questions".

I think one consideration should be Wisconsin air cooled engines. They worked years and years unchanged and would start every time they were called upon. They had their quirks, yes, but once you learned them and compensated for them they wouldn't let you down any time of year. I was interrupted during an oil change on mine and ran it 1/2 hour with no oil, I got sick to my stomach when I realized and shut it down. Filled it with oil and it still runs today nearly 20 years later!

Flathead Ford 4cyl, Ford 9N. Built in 1939 and never been opened up. Not even a valve job. I don't know how many hours, but it's 70 years old and doesn't drip a drop of oil. Been in the family since new, have all the records of maintenance and original bill of sale.

Mopar 225 slant six. I know of several with over 500,000 miles and never a problem. The bodies rusted away but the motors kept on going.

:notworthy:notworthy

9.2 Wisconsin in my 4 mortar mixers. 1985, 1986, 1986 1987, End of story I just retired them because they out lasted the mixers and parts for the mixers not the engines. The engines are in a container except one which I need to pull. Few carbs, fuel tamks (my errors) and points but never dissassembled in all those years. Now all I can get is a honda:nono

sad it will never last that long. At least with points I would hear it coming new motors boom they are off and you are stuck. Points where's the file for a few days weeks running.

Well, okay.
How about one of the most mean....

Mid eighties BMW F1 "Megatron"
This engine was producing around 1,500 HP in qualifying trim, down to a lowly 1,200-1,300 HP in race trim.
The cylinder blocks were from the 2002 road car and some of the "superfluous" ribbing was removed.;)

It is a 1.5 liter 4 cylinder engine.

A lot of people do like the Toyota diesels. The only Toyota diesel I owned was a 2.4 turbo in a 1985 pickup. Bought it new, so it wasn't that a previous owner abused it. It gave horrible fuel mileage and burnt lots of oil. Got rid of it at about 110,000 km and was glad to see it go. Maybe I had a lemon??

Cat 3106 in a machine, not a truck. Really under powered and will run a good 20,000 hrs with no rebuilds in most cases. Keep the oil changed and new air filter and she'll run 4-ever

Steve that brings back an old experience. Back in the day, early 60's. I was about 15 years old and my granddad built me a 18ft skiff, with a new 9hp Briggs and Starton (spelling) we used these skiffs to harvest blue crabs. I was the only one in my village (out of 8 skiffs) that had the B&S, other had the 7 1/2hp Wisconsin. My skiff you out run all the others (I know I had more HP) All the owners of the other skiffs were older men and they didnt like that. Now to the story, my skiff got caught under the dock and it sunk over night, my Granddad and myself, got the skiff up and we flushed the engine with fresh water and dried out everything and put in new gas and oil, it started the second pull (pull cord, not recoil) amazing. I ran it for 2 more years, before getting a 4 cylinder and 22ft skiff.
Seems like the Wisconsin engines always had problem with moisture, in the mag, but they were good engines
Sorry again for the long story, got carried away again

Those Wisconsins have done untold amounts of work over the years and have powered just about everything. My buddy has a self propelled Gehl hay mower/conditioner that has a V4 Wisconsin in it that he uses still today. I've seen them in skid steers and any stationary machine you can think of, they sure have done a lot to build this country.

The early JLG lifts, like the 30F, used the Wisconsin VH4D.

Hi Guys,

One of my many jobs while in high school was tieing wires on a Case hay baler with a V4 Wisconsin engine. No electric start. After cranking and cranking one morning I asked the boss why he didn't have my dad fix it so it would start. He said I can afford you but I can't afford your dad.
