Them Moron(s) is the EPA and they have been hard at work shoving stupid ideas and mandates that essentially gave birth to the EXHAUST GAS RECIRCULATION circuit since oh.......say........1971 - 1972 circa. The death of the muscle car? The death of our fun today in the near future? That dirty nasty air has been and still is runnin through gasoline engines where it first originated. Most of the garbage present in the intake is engine oil that found its way there via a Positive Crank Case Ventilation System. This also found on gasoline engines since the dawn of time or near after but every engine (Gas or Diesel) since its idea has one. My point is that it is NOT Fords or Internationals fault and it is NOT a fault of diesel engines.
Is it in the engines best mechanical interest?? Nope. That is why there is the aftermarket and us crafty gearheads who eliminate the stuff for efficency, performance, cleanliness and reliability. The intake if you cleaned it will be gunked up within a few months if you haven't re-routed the CCV to prevent the mess.
