6.4 Engine Life Expectancy
 

What do you guys think the life expectancy of these new diesels are?

Given that simplicity is no longer, the age of KISS has been over taken by how complicated can I make it.

Do you think we'll see 300K miles between rebuilds? What about all the added "stuff", DPF's, injectors, plastic degas bottles, plastic radiator caps and charge coolers?

Projecting in the long term, I don't see these trucks lasting as long as their predecessors.

Oh, lets not forget the electronics........

I got a flyer from my local dealer offering a 200,000 mile warranty on the 6.4's. If FORD is willing to warranty them for 200,000 you would think they are confident in the longevity of the 6.4's.

If they are maintained properly and cared for I don't see why you can't see 300K out of the engine but I definately see problems with some of the other items you mentioned.

gwcon, I agree the core engine may last 300K miles, but the truck as a whole I'm hoping has the same reliability.

My friend has an '03 7.3 with what looks to be a similar material degas bottle and it looked in good shape.

Now, my '96 F250 (which I don't own any longer) did have a problem with some plastic parts... Again, the longevity of plastic parts is questionable.

These trucks are definately built solid. However, you are right you can only get so much life out of the plastic and rubber(gaskets, hoses and seals) parts.

International claims a B50 life of 375,000 miles, inotherwords they expect 1/2 of the 6.4s they produce to not need an overhaul before 375,000 miles.
By comparison the DT466 is claimed to have a B50 life of 450,000 miles.

I would think they can do 300k but don't go so long between oil changes as the owners manual indicates.

It says 10,000 miles for regular use and 5,000 for heavy use (towing or bio diesel use).

I personally change it around 3,000.

Plastic is plastic enough said.

Mine only made it 41000 miles before the motor blew....

I hate that you are having problems but there is more to it than the engine just blowing. Something went array. Any detailed information.

I have talked with several FORD diesel techs at several different dealerships and they have stated that the 6.4 has been a very reliable and solid engine after they got over the first production problems.

I too think we need more information. There had to be some other issues going on.

I'm a new to diesel's I just tbought my first one, but I can say this about Ford. I have a 1993 XLT F150 with the 302 and it has 220K miles on it and never had any trouble, and I have a 2001 XLT Explorer that just turned over 235K and I have never turned a bolt on it either and didn't buy them new. I trust them so much I gave they to my daughters to drive. Ford is the longest lasting and toughest out there!!!!! Synthetic oil does help too....

Its all about the maintenance. The core engine should have no trouble going 300k+ if you follow the rules. Im not even worried about the electronics on these trucks. The emissions scares me though. Already we have seen problems with the DPF. they are supposed to be good for 150,000 but I have a hard time seeing that happen. I had mine replaced with less than 3k on the clock. I have a hard time thinking it will make it to 150k now.
In the 70's people wouldnt order power windows because "its just something more to go wrong, anything electronic is going to break". How ridiculous does that sound now?
In the 80's when fuel injection got popular people said "any time a computer is involved its going to fail". Lets see a show of hands how many of you would go back to a carburetor on your daily driver.
Plastic degas/overflow bottles have been standard since at least the early 80's (I had a 79 mustang and a 82 LTD that both had plastic).

You make some very good points!
:-drink

I wouldn't worry too much about the plastic parts. They make Glocks and other guns out of plastic!

Ours made it about 36,000 miles.

But for the majority of owners, I'd say 200K+. Now the truck and DPF will probably be beat down and I've heard that the DPF is only supposed to last around 150K miles, but that's just what I've heard around the forums.

I'm not worried about the engine, turbos, electronics, ect. It seems like this truck's annoying problem is going to be radiators.

life on 6.4
 

if it lasts 200k cad on aford to pay to have it fixed my 2008 has 45000 and sence june 2008 it has run 5000 miles and been in shop 5-5 1/2 month of that for does not seen to know what is shutting it down
