N14 Rebuild

mmalutki, I have over 100k on the overhaul now. I still have the same problems. The only change is that the chatter noise is louder. I had the overhead set twice. Put it on the dyno and every thing checked with out 92% power to ground. Took it in and had them tear it down again and they can't seem to find any problems. I have no clue what's going on with it. I'm just going to run it until it stops. I have no idea on what's causing my problems. Oh I replaced the air compressor because they thought that was my chatter noise. Still chatters LOUD at 1400+ rpms!

 

Old post I almost forgot about. Since there is new response to it I will update things a but to help others out if they have the problems. Cory Wood I did install new heads and injectors when the overhaul was preformed. I had my local freightliner dealer in Kansas do the work. I don't idle much at all is the thing.
To update some things. During the fall we found the ticking noise. I noticed it would go away for a few seconds when I used the engine brake. Sure enough we found two broken retainer springs on the "C" brake. Last week I lost injector #4 (fault code 332). After just replacing that injector I noticed that awful chatter noise I've had for the past 3 years quieted down quite a bit. You really gotta listen for it now to notice it. I wonder 3 years ago if the 6 pack of Cummins injectors had one or two of them that were slightly faulty causing a fuel knock of sorts. I plan on replacing the other 5 and seeing if the chatter goes away completely. I've been running it hard for the past 3 years now with these problems. Other than the awful noise it runs fine. Still using 1 gallon of oil every 3000 miles. If I add Lucas to the oil I can get about 5000 miles before I have to add a gallon. I really think when it was overhauled the dealer did a half ### job and never would stand behind their work.
