Are there any problems with the ISX engine?

Like any other engine with an EGR, the system can cause some problems. On the ISX, it most likely has to do with a leak in the EGR valve. This is a difficult problem to diagnose, but monitoring the coolant consumption can help. If you notice that it’s using a larger amount of coolant than normal, it’s probably worth investigating further.

Why are the Rockers on my Cummins ISX not working?

The CM-871 used a second cam to run the injectors, the 2250 and 2350 use a Bosch high pressure system I believe utilizing a 3 head pump on the 2250, and a two head pump on the 2350. These pumps will fail at around 400,000 miles, if not sooner. When they fail, if not caught in time, will destroy the motor.

What kind of emission system does the ISX have?

Why does my Cummins ISX engine flatten out?

The ISX also has a history of camshaft issues. We discussed this briefly in Cummins ISX Engine Spotlight. In short, an ISX camshaft can flatten out.
