    Bump....Any more updates on your engine Chevy? I sure hope they found the problem that you'd been chasing for so long.

    They have done everything they can to try and diagnose this and can not figure it out. They hooked a mechanical gauge on IVA rail and pressure is normal all the time.

    So to recap;
    -new injector/ iva harnesses
    -new engine harness
    -tried 2 new housings on 5 and 6 actuators
    -tried a new ecm
    -new check valve in iva rail
    -new pressure sensor
    -new iva control valve

    Nothing has helped, I am just going to drive it. Whether or not it is even affecting anything I dont know.

    Theyve been in contact with Cat the whole time, and everyone is stumped. They have almost 50 hours in this thing.

    That's depressing ..... Is this a cat dealer or a truck dealer certified for cat work ?

    And do they admit there's a problem?

    Depressing is right. Cat dealer, yes they admit theres a problem. But also say it may have no affect? Lol

    Chevy any updates on your truck? Did you get it figured out or are you just running it the way it is? Thanks
