    I have a 2006 international 8600 daycab and my air only builds up to 90. I drained all air tanks still doing it. Air bags won't go up, I replace leveling valve same thin... would this be a result of a bad pop off valve.

    Probably a bad governor, or a massive leak in the air suspension. Leave your suspension dumped and see if it builds up to full pressure.
