      smell in cab

      exhaust smell in cab while stopped at light/sitting in while idling, whirring/pulsing sound coming from right passenger side engine when hood open also bit of smell coming from that area. smell in cabin usually when defrost or any air is on, also tried in air recirculation mode, still smells

      ive ruled out that it could be exhaust from other vehicles nearby as this has also happened while parked 40km up a bush road in the middle of nowhere (no vehicle to be seen or heard for miles)

      my guess is it is something to do with exhaust manifold

      any insight is appreciated.
