N14 Rebuild

false i dont think the rings have seated or sealed or whatever the correct word is on the blowby and smell. i have no idea what the noise is maybe compressor or accessory drive.

 

Not normal. Mine ran just like it should from the moment we started it up after the o- haul. Wonder if one of the rings got broke putting it in. Did they use cummins parts or after market

 

Sounds like the shop is telling you this in hopes that you will keep driving it and the warranty (if any) will expire without fixing it. You should take it back and speak with manager. If that does not work keep going up the chain of command. I would call cummins and see if you can get this resolved before it is to late. Keep taking it in and bother them if you have to get it solved.

 

Yeah you have a problem there. You should not be using any oil or finding puddles and no noises. Get it fixed quickly before you have a major issue.

 

Hows your oil pressure? engine temp? EGT temp?

It might be a loose turbo charge air cooler blue hose for lack of power or low mpg.

Oil leaking might indicate a higher problem. Did they run overhead after done? Do you have any "color" smoke on startup, reving or deceleration?

 

The noise is most likely the overhead was done incorrectly that would also explain the low power and fuel milage drop,also the worst thing you can do is idle a fresh motor i drive everyone i overhaul hard if your. Idling for long periods then bump the idle to minimum 900,the oil problem sounds like either glazed liners,damaged rings,or incorrectly positioned rings

 

Hi i'm new hire, end i have same problerm on my N14 like you. My engine is after complete overhaul end same problems, do you fix your engine, whats happend?
