The gaskets on the cam followers that I took off were much thicker than what the rebuild needed. Originally the stack was around .050 and what I ended up at was .024. If all the other parts are equal that means the engine was far too advanced. I also rebuilt the step timing controller and calibrated it. Adjusting it on the bench with air pressure isn't the same as on the truck with oil but I'm pretty sure it was way off too. It was staying in advanced mode for too long

All this is probably just an amusement to you ISX guys. I hope I'm not being a poser by painting the engine red. I hate dark colored engines almost as much as cummins poop beige. The 444xt color was originally called bluk or bluck. Black with a little bit of blue in it. I guess that was to hide the oil leaks

That engine should not run more than about +8 BTDC under full operating load in the mid-band. +11 BTDC is pushing things on the upper end, considering its lower compression ratio and longer piston rods vs. newer engines.

Install a Pyro and an oil temp gauge into the truck and you can ball-park weather or not the engine is in the right injection timing ranges or not.
