1996 525 n-14

N14 is a good motor. injectors can be an issue on some of them, not all. and they injectors are expensive. see if there is a repair history on the truck. And i'd never buy a truck without a dyno run it can tell you tons more then you think

 

How is it a million mile motor if you gotta pull the heads? lol. Thats major work, also it usually needs bearings at 600k so i wouldnt call it a million mile motor. I had one and left a very very very sour taste in my mouth, never to own one again.

 

They all break down, they all have their problems. Most everybody i know has a cat, some have had good luck and some have had problems, 2 c-15's never made 500k before everything but the cylinder kits replaced, another made 500k but the oil filter spun off and took out everything, a 3406 with hot codes, power box and a stage 3 charger made 700k before an o-haul and now at 950k is drinking water plus has crapped 3 not very old injectors in the last 2 years, a bridge cat thats had atleast 1 or 2 holes replaced under warranty and also a turbo from those sleves inside the manifold going through it, a c-15 with marine inj and big charger @450k needed a head gasket and bearings. But I also know a guy with a c-16 with over 800k on it thats had marine inj and stage 5 turbo on it since it was 2 weeks old that has only replaced the oil cooler and a couple of those inj. and another guy that just o-hauled his c-15 with hot codes and a power box with 950k that had only replaced the oil pan. Most of those guys got their money's worth out of their motors. I would own a c-15/16 but I would not turn down a truck that I really wanted just to have one

 

I had one it was set at 460 injectors and ECM are both junk and expensive to replace those was the main problems I had oil pump always seaped the E7 I have now will pull more idling than the N-14 would on the mat

 

what do you need 100psi of oil pressure for, 10gpm # 30 psi is the same as 10 gpm # 100 psi unless my math is wrong. Also I believe injectors are about the same price for cat or cummins

 

I had a N-14 injetors was $450 a hole fuel pump was $900 ECM $2300 it ate 2 of those so tell me again how cheap a Cummins is to work on

 

Cummins less problematic? WAKE UP. They dont call them cumapart for nothing
