Hypoxia Posted February 8, 2022 Share Posted February 8, 2022 (edited) I aired up the coach with shop air and heard an air leak from 20' away. It was the Holset Turbo Actuator Air Control Valve 3770742 . Inland Kenworth had it in stock so a couple of hours later and a much lighter wallet that leak has been resolved. Who knows how long it was a small leak and in an inaccessible spot that I probably would have never discovered it.
