In our school area, Wake County NC, there was a story on the local news about the school system needed some 1 million additional dollars for bus repairs due to engine issues with them.

I also see in Atlanta is have the same issues. Most of the buses were purchased in 2006-2010. the issues seem to be the EGR,, just like in the 6.0L engines they provided.

Even the Powerstroke help guy made a video of how he is done working on the 6.4. Funny as hell as he is really aggravated with the 6.4

 

Oh for the days past of the reliable diesel. Change oil, coolant and filters, don't mistreat them and they would economically run for ever. Then, comes government.

 

One of my clients had a 6.4, he loved it. It l looked great and ran great, he drove it frequently back and forth between Tucson and San Diego where he kept his sailing yacht. Always serviced and cared for, never even towed with it, just a camper shell. Last week he drove up in an Expedition, I said what's up with that? He said the 6.4 grenaded on him without warning and the cost to repair it was more than the truck was worth, so he threw in the towel and drove home in the Expedition. He had less than 150K on the 6.4.

 

Are the 6.0 and 6.4 engines that are used in the Fords International engines? I thought that they were Ford engines and that Ford and International were no longer doing business together.

 

all diesels used in Ford pickups were built by Navastar except for the 6.7.

 

They really need to get rid of EGR entirely and go to an "aftertreatment only" emissions solution. Cummins already has EGR-free engines that meet the strictest European pollution standards but I don't think they sell them here yet for on-highway use. They actually license other diesel engine makers to use their aftertreatment systems.

 

That guy is hilarious. He made a video of a 6.4 that came in for repair "here's the only part number you need to fix this one" and pulls the cover off a brand new crate engine.

He makes his money fixing 6.0's, which are not bad engines once they are straightened out. 6.4 is the only Ford diesel, or pickup diesel period that I would never go anywhere near for any reason.

 

In one video Bill did, Powerstrokehelp.com guy, he was driving a 6.4L and was saying it was not if but WHEN the engine would blow. Like bibB56 was telling of his client with one that was well care for can blow.. got me thinking when I need to upgrade from the 7.3L might be a 7.3L gas engine. same size less crap. LOL

 

Mr. Hewitt refers to them as "Throwaway engines" lol!

 

 

so international is in hot water for problems that are arising with engines that it has not made in over 11 years?

 

2019 - 11 years = 2008.

Ford offered the International 6.4L through model year 2010.

Navistar renamed the 6.4L to MaxxForce 7, and carried on manufacturing that engine for several more years, in several applications, long after Ford parted ways.

Some of the applications fitted with the MaxxForce 7 6.4L diesel engine include school buses, as well as the Terrastar through model year 2015, the Durastar through model year 2016, and various motorhomes (ie Nexus Ghost, Thor Serrano, etc) as recently as 2018 model years, although in the case of motorhomes, the model year of the coach can be 2 years later than the model year of the chassis. Navistar purchased (and later shuttered) Workhorse Chassis, which fitted MaxxForce 7 engines into stripped chassis platforms for coach builders to build on.

While there has been a lot of news over the years about Navistar using a bank of EPA emissions credits to manufacture MaxxForce engine through 2012, there were a lot of different displacements of engines utilizing the MaxxForce brand name. MaxxForce 5, 7, 9, 11, 13, and 15. Some of those MaxxForce engines were discontinued in 2012. And some, like the MaxxForce 7, continued production. I found emissions certifications filed with the EPA for the MaxxForce 7 up until 2015, but my search was not exhaustive. (ha ha). Given that the Durastar could be ordered with a MaxxForce 7 up until 2016, we are really talking about an engine that has been produced within the last 5 years, and therefore could still be under some original engine warranties.

 

oh, ok. i read the first post as the issues were with the 6.0, or DT 365 as international called it.

 

The MaxxForce 13 in particular they had serious problems with in the full size Prostar rigs for awhile there back in the earlier 2010's. Relied way too heavily on EGR to meet the emissions numbers and would clog the motor and DPF unit all the hell. Very expensive repair bills and I think quite a few lawsuits ensued. Eventually they turned to Cummins for help with the emissions packages and that straightened most of it out, but the hit to their reputation was bad.
