Detroit Series 40 Engine history

Hello all, Don here with a few questions on a Series 40 engine. Does anyone have the Pro's and Con's of this engine?
What problems and maint.issues will I be looking at.
What mileage should be expected.
What track record does the fuel managemant system have?
Tell me all...I can handle it!
Any advise I would appreciate, thanks, Don

Were you able to get any info on this engine? I am looking at a 1996 CC Magna with a 330hp series 40 engine and am currently trying to get the same info.

I believe that the Series 40 is actually the basis for the MaxxForce 9 in the configuration you are looking at; Navistar did a distribution agreement with Detroit Diesel right around the same time that (the then) DaimlerChrysler (now Mercedes) acquired Detroit Diesel from the Penske Group.

The Green Machine -- 2000 Mountain High Coachworks Summit (Spartan chassis / Cummins ISC)
...and F-Troop: Fearghus, Fiona, and Frankie (Cairn Terriers)

Series 40 Engine

What DDC calls a Series 40 is in reality a Navistar DT466 engine which is a great mid range turbo engine and very popular. Must be thousands of them in rental trucks like a 24 footer Penske or Ryder etc.

I think the only difference you will find is the color of the engine and the valve cover.
