    Sounds like the the clutch isn't disengaging. Does it die if you put it in Neutral before coming to a stop?

    Hi, I have a Mack SXU VISION 2014 with motor D13 MP8.
    I have a leak in the exhaust leak with the smell of oil and gasoline
    I have checked the head and the turbo, and both are good
    Does anyone know what else should I check?
