I have a 2008 Mack CH613 with the MP8 motor. There is a very loud squeal coming from the turbo area while idling. It goes away for a few seconds after building rpm’s, but will come back. It’s not a whine, but it sounds like a dry bearing. The turbo is tight with no impeller play. Any body else have this problem?
