Cummins ISX CM871 Technical discussion

you dont need them, all you need is a zappit for insite, or to just unlock it with caltherm. Its not like cat or detroit.

 

I PM'd you, call me

 

I was told by someone very, very good with the ISX and the N14, that cumins addressed the well known premature wear of the N14 bottom end problem on the ISX, extending the life of it. Better oil flow etc. He said that if the bottom end of the N14 was done at 600k intervals, the rest of the engine would typically last upwards of 1.5 to 1.8 million miles without a rebuild. He claimed it was the bottom end that caused the accelerated sleeve wear, and the further past 600k, the higher risk of spinning a bearing when the engine was cold, especially if you rev it up suddenly with no load. He then went on to say that the ISX was identical in nature, but that the bottom end lasted an additional 200-250k before these risks, depending on how much more soot from the EGR there was in the oil regularly. His final opinion is that cummins improved the bottom end and other areas of the motor to make up for the extra wear that soot would cause because of EGR.

I cannot see any flaw in what he said, so I guess the question is weather or not you have a bypass system to remove soot from your oil, or perhaps have EGR disabled for most of your 850k miles, or not. If not, then the bottom end at that mileage would be a wise choice.

Just don't rev it up fast, or high when its really cold in the meantime.

 

I will be at the TA truckstop this weekend (sept 1-2) outside Seattle,wa at the base of snoqualmie pass. Anyone can PM me if you want to meet up and BS a while...Rawze
