This site your on is the #1 source for consistent truthful fact based information in regards to cummins ISX engines. No other site even comes close!!

Just start reading and asking questions. Ya I know, you got other things to do and can't sit around reading forums all day, I get it. But if you want to be successful with today's emmission controlled engines you have to take it upon yourself to learn the ins and outs of these engines.

You might think you made a mistake buying cummins, but actually it was the smartest thing you could have done. Like Rawze said, you can buy the cummins software and inline adapter for about $300, open a free quickserve account and now you have access to all the exact same information the dealers have, all parts breakdowns/part numbers, all service procedures with torque specs, all diagnostic tests, etc.

There is a short list of rules you need to live by if you have an ISX, in no particular order....

1...don't lug them down below 1500 RPM this is what causes liner failures and premature inframes.

2... don't use aftermarket parts on them, use genuine cummins only

3... set the overhead about every 200k miles and make sure you are using a maintenance free crankcase filter to eliminate backpressure that starves the cams for oil.

4... if the emmission system is still active you need to do an egr tuneup about every year to keep the system operating properly.

5... if you have a common rail isx, replace fuel pump guts every 400k miles to prevent catastrophic engine failure.

6... if it's demandated, send a copy of the file to Rawze for review because it's most likely a bad program and will result in very premature engine failure and lots of headaches leading up to that.


7... when it's inframe time, do all the extra stuff mentioned on this site ( can get into those details another time)

Maybe a missed 1 or 2 but those are the big ones.
