2013 International 4300 26ft 6.7L No Def?? California ?.

That is not a 6.7L. That is a 7.6L maxxforce DT.
They do not use def.
And they are steaming piles of garbage.

 

No idea on California compliance, I'm in Canada.
Those engine were extremely hard to own from model years EPA 10 till they were discontinued in about 2015 in my experience.

Epa 07-10 weren't great either and definitely not California compliant.

 

DEF isn't required on anything. All the EPA cares about is what comes out the stack. How the manufacturer chooses to meet the targets is up to them.

If the emission system is 100% factory, Navistar probably opted to jack up the EGR rates to obscene amounts.

 

Yes they did. Massive egr cooler, twin turbos. Pure junk.
They never did meet emissions, Navistar was fined and forced to switch to cummins power on their medium duties.
2 contractors here each had 1.
1 was bought new. With the very best extended warranty Navistar offered. Warranty spent over 125k$ on it in 7 years. 2 inframes, turbos, injectors etc.

Other contractor bought one used and deleted it. Engine blew up with 3 months and I never saw it again.

Worthless on trade or sale.
Freinds don't let Freinds own maxxforce anything

 

In order to determine whether the vehicle is legal to drive in California, you can go to the CARB website. It is all done according to the emissions level on the label on the engine. Put in the required information and they will spit out the current regulations. they might even be able to do it by VIN.
Something tells me it might still be legal, but in the not too distant future it will not be.
I concur with the other opinions about Navistar powered trucks during these model years.

 

Sell it.

get what you can for it, then stop buying things that you don’t understand how to determine if it is any good. Buying a truck is not like buying a car, buying one at auction sight unseen is dumb and a crapshoot unless you have a lot of experience with truck purchases and evaluating one.

biding on one for the California market isn’t good either.

to add to that good advice, I would have taken the vin to the leasing company to get their records, and the dealer to see what was done to it at the dealer. If I could not see it myself I would have hired a mechanic to go see what’s wrong with it and then determine from there if I wanted to bother with it or not. I would also have him/her do an ecm dump of just the error codes to see what it had in the past.

Normally I would have had the truck on a dyno, this is the only way you get a blowby test done and that determines if you need rings, but seeing it is an auction truck, that step would have been skipped and I would risk it.
