ISL 9 2014 opinions

[cybernetictrout]

hello everyone. a good customer of mine, wants to get rid of a Isuzu NPR and buy a bigger refer truck. i told them to start by looking for something with a , dependable ISB series cummins engine. but right now locally, in my area of the USA. My customer can only find the ISL9 powerplant, in a refeer configuration. can anyone get me the ISL 9s engine millage maintenance guide for when the, engines supposed to overhauled. should i, have to be very weary of the ISL9? ,i dont think its a cummins designed engine, isnt the ISL9 a pacar design?, im not certain if thats true?? can someone explain that to me.

i called the salesmen and asked if i could plug in cummins insite for my customer, to make sure the emissions system is working properly and salesmen neil said "it has a check engine light, its probably just a nox sensor, but hay im just salesmen here at a mom and pop dealership, are shop has been backlogged with work and we just havent been able to get to it." im thinking they will leave the NOX sensors disabled so i wont be able to check the health of the emission sytem.

the truck has 250000 miles on it. most likely city miles. which i know is never good for emissions trucks. i also have seen few ISL9 come through over the years and the always seem to worn out pretty bad already by the time they make to my place
