2021 Ford E-Series No V-10

Meh, I owned a 6.0 for 10 years & never had an engine related issue, but then again I never chipped or modified the powertrain in any way. The 1st year of them (2003) Ford cheaped out on the IH spec'd injectors. I would say the 6.0 was a horrible engine to hot rod. For years every time I was at a fuel pump & someone else was there with another 6.0 I would ask them if they had lots of issues, it was very rare I ever encountered someone who said they did and 99% of those guys were running chipped trucks.

The current 6.7 Ford diesel has been a great engine from the day they started selling it to the public. The 6.2l gasser was a good engine from a reliability perspective over the many years Ford offered it in the Super Duties. The 7.3 gasser should be no different. Say what you want about the 6.0 &/or 6.4 diesels but those were IH engines that Ford did stuff to that didn't help. 6.0s that were used in medium duty commercial trucks that were untouched by Ford's hand, had/have a good track record.

Haven't had a Ford pickup for a number of years & even more since I had a Ford diesel pickup.... I'm not a Ford guy per se, just someone who's owned some of them & noticed how people chipping & otherwise messing with OEM power tend to cause a whole lot of problems (then blame the manufacturer). FWIW, the worst diesel vehicle I've ever owned in my life was a 24v Dodge/Cummins. The list of **** that went wrong with that truck was biblical (& MANY of those issues were with the motor, which if you believe people all over the interwebs, are engines that are beyond bulletproof. Lol).

Ford went back to push rod design because they are better at developing torque at lower rpm, what you need in heavy vehicle like a motorhome. Overhead cam develops power better at higher rpm, better for performance vehicles like sports cars and motorcycles

There are many gas engines out there with direct injection but the new 7.3 is not one of them. It even has pushrods, not OHC like the V10. It's not proven yet like the V10, but it appears to have durable, proven design features.

My 2020 Entegra Odyssey 24B class C with the 6.8 costs $74,995
The new Entegra Odyssey's 24B with the 7.3 now sell for 94,995 at the same dealership that we bought ours at.

In 2011 I bought a new 2011 F250 with the new 6.7 diesel, which had been advertised to have been a million-mile tested in the hot deserts and freezing conditions etc. etc. Guess what, for 2012 the 6.7 had been changed, then again changed in 2015.
The Ford 6.7 diesel is an awesomely powerful motor, pretty efficient, but way too complicated and way way too expensive to have work done on it after the warranty expired.
After all these years, guys in the know are still looking to buy the old Ford 7.3 diesel with less HP and torque than the new motors because it's a lot less expensive to repair and they're a lot more reliable.
I'd be concerned that the new Ford 7.3 gas motor will be too complicated with the new 2021 EPA and Euro smog equipment and that they will have direct fuel injection. I prefer the older Port injection.
On a side note, a few months ago I traded that 2011 6.7 F250 diesel (they gave me $35k.) for a down payment on a 2020 E450 Entegra Odessey class C ($74K) with the 1990 era, zillion mile proven 6.8 V10.

The Ford v-10, the GM 283,the Chrysler slant 6 and the MB 5 cylinder diesel are my top choices in reliable well designed engines. Also the GM 250 straight 6 were bullet

proof. Ford put a weak tranny behind their diesel pickups in the early 2000's GM put the Allison. That tranny is amazing.

I would not go with the new engine either, the consumer ends up to be the test pilots. Often when a few MPG is waved around consumers go towards it.

A close friend of mine is a Ford technician. He said the 6.0 diesel was a great engine to earn a living from. He said it was a severely flawed design. Most were installed in pickup trucks, but there are some E450s with them. DO NOT own one for you would soon regret it because the repair does not last. Adding that the engine never had the reputation in other ways compared to other diesels. It was a poor performer and not as good on fuel as hoped. It rated poorly in every category.

The V10 had it's issues in the early years, most notably was the lack of threads in the heads for the spark plugs. I heard there were only 4 threads, later doubled to 8 threads in 2003 or 2004. It took that long to get that simple problem addressed properly.

GM's track record isn't any better.

I personally would be uncomfortable to have a recently introduced engine, especially working it so hard as in a motor home. We also keep our motor homes 4 times longer than a car. So whatever we buy, any design issues would be with us for a very long time.

I've got an '89 E-150 with the 300-6 cylinder and the 4 speed stick +OD.

The 6.0 diesel was a great engine.:R Every time you took it in it was $100. Oil change was more.

At the 100k mile mark I dumped it.

Remember the 6.0 Diesel, what a flop that way.

The 6.4L was nothing to "write home about" ! Did they ever put it in an E-series chassis ?
