Such a questions don't exist in the case of 7.3

 

You know that the 7.3 can still break/wear out, right? Just go look in the 99-03 7.3 forum.

 

I post more out there, than here.
Most of the problems with 7.3 are the modifications.
That is why I keep my stock. Why would I worry about something that might happen in 10 years ?

 

I know, but they still wear out or break, even stock. Every engine does.

 

Sure they don't-just keep telling yourself that.

If that was antifreeze that got into the oil, every bearing in the truck would need replaced. Every rod bearing, the main bearings, turbo bearings, cam bearing... basically the entire engine would have to be stripped and rebuilt.

It's possible went he piston went bad, it let some antifreeze by and into the oil...

 

And gas engines are designed to produce heat instead of power? Seriously, every engines is going to be designed to make as much power from the fuel they consume as they reasonably can.

Just FYI: The most efficient diesels on the road (which are not in trucks) only convert about 50% of the energy into power. PSD's are probably closer to 40-45% efficient. The 6.7 might be pushing closer to 47 or 48%, I'm not sure.

 

Thanks, you said what I meant. A look into any of the diesel forums here will prove my point that $10K is not exactly out of the question when it comes to diesel engine repairs. Do I think it's reasonable? No, but it happens often enough. If it would make you guys feel better, how about a $5k repair bill as an example? Those happen with shocking regularity, yet are seemingly overlooked on this thread. I was speaking to a logger yesterday who has a couple F350's in his company, one with a 6.0 and one with a 6.4. The 6.0 has been trouble free, while the 6.4 is a regular patient at the Ford dealer. Sounds backwards, but it's true. Now while the problems have all been under warantee, what if it were a couple years older and they weren't? Ask the member on another thread who owes $35K on his F350 KR and can't keep it running, yet was only offered $15K on trade-in what he thinks of his diesels proven reliablity. All engines can and do expire, the difference is I can slap in an entire new V10 for a few thousand in my garage at home, that is if it ever breaks, which is unlikely. I have yet to meet the guy with a 6.4 who does his repairs ( as in engine swap) at home. One peek under the hood of a 6.4 will tell you all you need to know about working on it yourself.

 

I've only seen one Veyron in person, but have read quite a bit about them. I also know at WOT they run out of fuel in 19 minutes But at least you'll be going well over 200 mph, so you coast on into a gas station. But before releasing the Veyron the engine was ran at WOT for days without stopping, yes it was probably connected to fuel tanker, maybe multiple tankers, but it did it without blowing up. that's making 1000hp with 4 turbos and 12 cylinders for days without any heat related issues. The key is cooling as I mentioned earlier, heat is only a problem if you can not remove it as fast as you produce it. If you can remove it as fast as you produce it, then it's not a problem.

No, a truck doesn't need 10 radiators, the Veyron has 10 because they couldn't put 1 huge massive radiator in the front do to aerodynamics. A truck on the other hand has the aerodynamics of a brick, so sticking a texas sized radiator in front of it won't really matter.

true, only 1/3 of gasoline is converted to power (for N/A engines anyway), but less than 1/2 of diesel is converted to power also. This will only help you get better mileage though, and I don't think anyone here is claiming the 6.8L V10 will get better mpg than a PSD.

 

Your talking about a 6.4 cab lifter Yeah, I would like to see Joe the plumber take the cab off his truck to work on his engine!

 

If a stock 7.3 can do everything you need it to, why mess with it? It's a good engine, even if it is dated. I wish I still had mine, the engine was great but the rest of the truck was falling apart after 14 years of use.

I can say my family put over 180,000 trouble free miles on that 7.3 over 14 years. I fully expect my V10 to do the same, although it may not have 180,000 miles in 14 years as I drive far less now. In fact I'll probably only keep this truck 10 years, and at my current rate that will be about 70,000 miles.

 

rep police got me. great post!!!

 

thats why newer trucks have a warrenty

 

Yup. And when that 6.4 cab-lifter doesn't have one any more... They are going to be really cheap.

 

Which is great, when you are using your truck to make money, to have the truck in the dealer's shop for two weeks. While the repairs are free, losing business because of a down truck is not something most people can deal with.

Which again is why lots of utility companies (and LIPA and National Grid are not small companies), contractors, you name it around here have gotten smart and are using gas engine powered F450/550's. I've actually spoken to some fleet managers around here, and the diesel's complexity scares them. Rightfully so.
