Not sure why it went bad but it seems to have bent the shaft no oil or coolant restrictions . As far as the boost its never gotten over 30psi boost in the two years I've owned it. I was told that these motors don't build over 30psi as they wont take it so I figured it to be normal. Same with The oil pressure being low at 25-28 psi at highway speeds. The oil pressure is the same as it was prior to rebuild and yes I put a new oil pump on it. All work was done by a local shop that several local friends/owner/ops sent me to. Every time I mention oil pressure to anyone I get the same answers (its a cummins they run low oil pressure). I run Mobile Delvac 15w40 and Fleet guard filters NO Lucas but I do add motorkote every other oil change.

I'm a detroit 12.7 guy this is the first ISX I've owned. I've always owned older trucks and done my own work but these things scare me to death.
