10 of the Most Reliable Six-Cylinder Engines Ever Made

Yet the British have the knack to build under powered engines that aren't reliable. :unsure:

I will say the I-6 in my late-sixties Triumph TR-6 was completely trouble-free. In fact the only maintenance I ever needed to perform on that car was to synchronize its twin carburetors (once and it was easy) and replace its brakes. It was a surprisingly well built vehicle that was one of my all-time favorite cars.

That Dodge/Cry slant 6 is a tank of an engine.

Agreed. I've owned and driven a number of these well into the 250,000 mile range. And of course, the Cummins that they mention is legendary. I bought my '90 Dodge diesel when it had 70,000 miles on it. It now has a tick over 420,000 miles. Only thing it has ever needed was the injector pump to be rebuilt at 220,000 miles, and the injectors replaced at around 400,000 miles. Love that engine!!!

As British cars go, the TR-6 is a beauty. (y)

As a young teenager in the late 80’s I installed a 240 Ford into a F100 and could not blow it up. I later went to a 250 Chevy and a 300 Ford. They were very good engines, just not too quick.I’ve had several of the 4.0’s with no mechanical issues.

Lotus installed Toyota engines in some of their cars? Wow!

Yeah, the Elise (and I believe the Exige) used the 2ZZ engine, which iirc was also in the Celica. Around 6500rpm the secondary cam (or however that VVT cam phasing worked) would kick in and would get you to just shy of 8500rpm insanely fast. I think there was a rev limiter at 8700 or thereabouts. The harder you pushed that thing the better it did, even on gas mileage.

But this is about sixes. As a kid in the 80's I remember when they came out with a specially badged V6 Toyota Camry, and my dad was all "nobody needs a 6 cylinder Camry." I'm confident he was right.

TR6 engine was a good performer for a tractor engine, made a great little Hot Rod.
 
Hmm. Reliability seems relative. The 4.0 is reliable, and probably one of the most abused engines out there, considering how many have probably run momentarily upside down out on a trail somewhere, but a lot of the others are pretty generic. BMW made many 6 cylinders, some of which were their most reliable, and others (like the S54 and N54) that are among their least reliable ever made.

They also spelled Cummins as "Cummings" in the article.

The Honda 3.5 is great... unless you got one of the VCM engines.

Unlike my ‘64 Austin Healy Sprite. That thing was a rolling full time hobby.

You gonna watch Hillbilly’s Bronco build on Robby Layton’s channel?

I just watched the first video. I was shocked at how stiff it looked. Surely the sway bar was connected, 'cause I'm pretty sure I've seen stock IFS Tacoma's flex more. I'm sure they'll be doing a SFA but and his channel probably isn't the right one to tackle this but I'd love to see somebody knowledgeable make the most of a TTB and cover how it could be improved with parallel links instead of radius arms, and things like where the roll center ends up. My hunch is that it's probably something like the halfway point between the axle pivots, which would be much lower than where it is with a track bar. Maybe that played into their reputation for rollovers.
