This is not to beat up an anyone here.. it is about learning and bettering ourselves with what we do...

you need to re-think your way of how these engines work,. what is tolerable and what is not.

the red engine maker has problems with liner height as it is. - When re-building an ISX... ALWAYS, ALWAYS ALWAYS -- EVERY TIME -- COUNTER-BORE IT IF IT HAS MORE THAN 400K MILES ON THE BUILD A----AND ALWAYS ALWAYS SET THE LINER HEIGHT TO NO LESS THAN 0.015" AND NO MORE THAN 0.016" --- I DON'T CARE WHAT THE MANUAL SAYS --


If you want a million mile engine.. that is what you have to do Cm870,
CM871, especially on a C<2250,.. AND -- ESPECIALLY ON A 2350!!!

You are now on a forum with people who know these engines far beyond what the factory want you to know about them ... trust me,.. there IS ONLY ONE WAY TO BUILD THESE ENGINE RIGHT,.. AND ANYTHING YOU DO that is even slightly less then what is recommended here,.... YOUR PISSING UP WIND AND NO ONE FROM THIS FORUM WOULD EVER LET YOU TOUCH THEIR ENGINE BECAUSE THEY ALREADY KNOW BETTER AND HAVE BEEN DOWN THAT ROAD!!!



some HARD FACTS/RULES ABOUT THE ISX...

* the HEAD cannot be re-used if a liner dances in the block, or if it blows a head gasket (only happens if a liner moved). It etches into the bottom of the head a few thousandths of an inch,.. and engine will not last long if it is re-used.

* YOU WILL NEVER SEE A HEAD GASKET FAILURE WITHOUT A LINER ISSUE TO GO WITH IT -- SO THIS MEANS IF HEAD GASKET FAILS FOR ANY REASON --- ITS COUNTER-BORE AND NEW OEM-HEAD! - THERE IS NO SAVING THE HEAD -- IT IS A THROW-AWAY ITEM!


* ANY NON-CERTIFIED ORIG HEAD, OR HEAD THAT WAS RE-BUILT/RE-WORKED BY A SHOP (non cummins certified re-machined head) -- WILL ONLY LAST 250K MILES (1/4 engine life) AND HAVE TO BE REPLACED AGAIN... THIS IS FACT,.. AND I HAVE SEEN IT A HUNDRED TIMES OR MORE-- I DON'T CARE HOW GOOD THAT SHOP SAYS THEY DID ON IT! -- THEY ALWAYS ALWAYS FAIL!!!- NOT WORTH THE FEW BUCKS YOU SAVE NOT ONE DAMN BIT!

* USE ONLY OEM BRAND NEW REPLACEMENT HEAD!! - ALSO head is only good for 450k miles for consideration of re-use. -- AFTER THAT, IF IT COMES OFF THE ENGINE -- IT NEEDS REPLACED NO QUESTION ASKED!!

* LETTING HEAD SETTLE OVER NIGHT before re-torque and final torque of head bolts.


* YOU CANNOT ALWAYS FIND ACCURATELY, THE LINER HEIGHT TO FIND A FRETTED LINER --<-- UNLESS IT IS REAL BAD!!!-- THIS IS A MISTAKE EVERY GODDAMN SHOP MAKES !!! - THE LINERS HAVE TO COME OUT AND THE BLOCK DEPTH CHECKED FOR VISUAL SIGNS OF FRETTING ETC.! -- AND SINCE THIS IS THE CASE -- EVERY DAMN ISX THE HEAD COME OFF OF, IF MORE THEN 1/4 LIFESPAN ON IT, OR IF LINERS ARE LESS THAN 0.014" HEIGHT TO BEGIN WITH, -- THE COUNTER-BORE + RAISED TO 0.014" HAS TO BE DONE OR IT WILL NOT LAST A FULL LIFETIME WHEN IT IS PUT BASK TOGETHER!!!!

* THERE ARE SO MANY GODDAMN BAD PROGRAMS AND BAD TUNING SHOPS OUT THERE FOR THE ISX THAT IT IS NOT EVEN SLIGHTLY FUNNY!!-- DON;T TRUST ANYONE!!! -- ANYONE!!!! -- NO MATTER HOW MUCH THEY BRAG.. NO MATTER HOW MUCH THEY CLAIM THEY ARE GOOD AT IT,.. NO MATTER HOW MANY PEOPLE SAY THEY ARE THE BEST!!! -- NO ONE!!-- NOT EVEN THE PEOPLE OF THIS FORUM WHO I PERSONALLY HAVE NOT REVIEWED THEIR WORK!!!!!! --- LEARN AND EDUCATE YOURSELF ON HOW THESE ENGINES SHOULD RUN AND HAVE ANY CUSTOM PROGRAMMIN CHECKED BY MYSELF, MOMMABURT, OR UNILEVERS ON HERE --- I DO THIS FOR FREE FOR ANYONE WHO E-MAILS ME THEIR FILE OUT OF THEIRE ENGINE -- AND NO I DON;T DO CUSTOM TUNING, SO THERE IS NO PROFIT IN IT WHEN I DO THIS FOR THEM!!! HAVE ALL PROGRAMMING VERIFIED OR LOOSE THE ENGINE PREMATURELY -- IT IS SOMEONE'S LIVELIHOOD AND LIFE YOU YOU ARE SCREWING WITH OTHERWISE!


-- READ, READ, and RE-READ everything on this forum!!--- YOU WILL EVENTUALLY COME TO THE SAME EXACT CONCLUSIONS!!! - there are countless numbers of horror stories about these engine, mechanics who think they know how to build one of these things,.. and only suffered as a result. - the OEM is actually the worst of them all!> and smaller shops know even less most of the time. -- IT IS NOT THAT PEOPLE DON'T CARE--- THEY JUST DON;T KNOW ANY BETTER! and then are too quick to argue with you instead of taking a moment to actually learn someting better for what they do.

WATCH and study my engine rebuild series.. i explain a ton of what i have seen and the right, and wrong ways to build these things. https://www.youtube.com/watch?v=LdTXWXKu...Zc_5ZwzDiw
