I have heard that the N-14 are pretty much a bullet proof engine. Is their any truth to the rumor. Have always been a cat man. possibly going to make the change. Thanks in advance for the help.

I have 10 N-14's running they are the electronic version of the old NTC 855 they all have 750K to 900K miles on them all have had good maintenance I haven't rebuilt any of them they all have had the injectors replaced $285 per injector times 6 fuel pumps on 3 of them 1 ecm they get pretty good fuel mileage you have to take good care of the coolant and coolant filter to avoid liner problems a few corroded wire probems but that is from our Wisconsin winter road salt overall really good motors.

Overall the N-14 is a decent engine although I am not a big fan of the N-14 STC engine.

I would roll bearings in 700,000 or so range. I seen to many spin main bearings around 800,000. I had one a month ago that was in the upper 900,000 and I said you should roll bearings soon but when I pulled the pan it was to late. One of main had spun and they didn't know it. Its a older local truck that hauls logs out of the woods. Put it back up and there going to run it till it locks up.

Seems to me that the injectors do more funny stuff than other engines. Like miss and bang or runs funny then goes away when your testing them.
