<p>[QUOTE="W923, post: 12379157, member: 329699"]I did a complete o/h on a n14 c+ around 2 years ago. It has gone through at least 3 sets of injectors and probably threw a rod today. This was a no expense spared overhaul literally every moving part was looked at and had new crank and cam injectors and everything else typical of an out of frame overhaul. My understanding is that the last injector failure destroyed one hole. I did not see it and it was done by another shop because the truck has changed hands. Now unfortunately it was purchased by a friend of mine about a week ago and something let loose on him today that caused oil to leave the engine and makes really bad noise when he tried to restart it. I am wondering if it ended up with a bunch of fuel in the oil and caused a bearing failure. I guess the bottom line of this long story is does anyone make a reliable injector for these engines at this point. Most of the injectors were replaced because of missing at low load/rpm but probably 5 total had more serious failures </p><p>This is all in approximately 350k miles. I even paid the freightliner shop to put a new set in it which seems to have turned into a smear against me because I apparently don’t know how to run the overhead and set injectors but the set they put in has had at least as much trouble as the ones I’ve done.[/QUOTE]</p><p><br /></p>
