Are MaxxForce engines THAT bad? There is a $20k difference between the MF13 & ISX

I would bet you are right as intl told me alot of my issues were from the owner not cleaning the dpf and filling the oil with soot hense plugging the oil filter .
I'm driving an emissions deleted 2010 isx at the moment and oil in it stays clean forever.

 

To be fair, I have a good friend who has a Prostar with a MF. While he's had issues, almost all of the issues were related to how international routed hoses and such. The motor itself has had very little issues, but he's blown more coolant lines then I can count. He ended up frying his EGR cooler because a coolant line wore through and before he could get pulled over, it fry'd the EGR cooler.
Keep this in mind, the MF especially does not like to idle. They will get sooted up very quickly and clog the do dpf filter.
I do know that there is a "fix" for the dpf system, but it doesn't solve the inherent problem that international tried to squeeze 8 lbs of excrement in a 5 lb bag.

 

Just curious what International would charge for the job?

 

That's what would mysteriously happen if I had one. I've heard a lot of these end up down in Mexico because nobody cares about that down there.

 

I've heard from a friend who ownes one 6 strategically placed holes drilled, and a small piece of flat metal added to the truck and maybe they work ok.

 

I've heard the little truck guys can pick up 3-4 mpg and bunch of horsepower if anything mysterious happens to their rigs at night.

 

I totally agree with the clean oil.

 

I know this is an old post, but for future reference for anyone else: The 2010+ Maxxforce 13 has a decent jacobs brake (stock in Prostars, optional in other trucks). It is just a lot of fleets tell you not to go over 1600 or 1700 rpm when the Maxxforce engine brake really needs to be 1900-2100 rpm.


For comparison, it makes about the same braking power as the DD13 until 1700 and then the Maxxforce becomes far stronger. The DD15 has about the same braking power as the Maxxforce from 1900-2100 rpm, but it makes at 1500rpm what the maxxforce makes at 1700:



The ISX has the most braking power -- it has as much at 1500 rpm as the Maxxforce does at 1900:



Keep in mind this is comparing a 13L against two 15L engines...

 

Google Maxxforce law suit and see how good that engine is
