Drtdigger4 Posted June 30, 2011 Author Share Posted June 30, 2011 No turbo really is working all the time even when u shut the truck at an idle u can hear the turbo winding down at first thought it was the actuator bit called the Mack dealer he said it's more than likely the vable on the other side of the motor. Kinda wander If there is any way to test that vave Quote Link to comment https://www.bigmacktrucks.com/topic/19578-04-mack-ch613/#findComment-80645 Share on other sites More sharing options...
