Cummins 8.3 330hp ?

Looking for pros and cons on this engine? Anything that I should look at? It's in an 2005 motorhome. with 49,000 miles. Thanks

  • Excellent engine. As with any larger diesel there a few maintenance issues (very low cost) that are unique to them and important-- such as SCA in the coolant.
  • I have the 8.3 in a 93 Safari here in NZ
    Motor runs like a dream and has never missed a beat. Our legal limit for this size unit is 90kph (56 miles per hour)and with the Allison 6 speed gearbox we are normally doing about 1600rpm for the limit.
    I pull a Ford Courier utility as my toad, and the engine has no problem sticking at the limit even on long climbs.
