  • Test drove vehicle to verify smoke concern. Removed air filter and confirmed rodents causing restriction. Removed spark plugs, PCV valve, crankcase breather tube, turbo intercooler tubes. Verified rodent restriction caused excessive vacuum on crankcase which overworked the PCV calve causing oil to dump directly into turbo and fill intercooler & intake with oil. Oil also saturated mass air flow sensor, creating rich condition that fouled out the spark plugs. Recommend performing BG EPR oil change with a BG air induction/fuel injection service as well as cleaning excessive oil from turbo area. Also recommend replacing air filter, cleaning out rodent debris from housing, and replacing spark plugs.
