Not anytime soon,Navistar has a contract that has 7 yrs left im i remember right.If you want a real diesel"no glow plugs" in your Super duty,you have to get it overseas,where the SD has Cummins B3.9 as an engine option in the F250-550 SD,the B3.9 is the 4 cyl version of the 5.9 in dodge pickups.

This is by no way a very detailed version of how a diesel runs, but here goes.
Unlike a gas engine, a diesel works on straight compression, meaning that when the fuel is compressed and that causes the fuel to ignite. In a gas engine the spark plug ignites the fuel.
The glow plugs are there for cold starting only. They pre warm the clyinder, and that helps the diesel fuel ignite when the engine is cold.

Dino, I understand every thing that you said. However in Johns post he says," a real diesel with no glow plugs". How would you start a "real diesel" in the winter?

To start a real diesel,just turn the key.If its real cold,plug it in,or hit it with a shot of ether.Direct injected truck engines do not need glow plugs.The reason to have a diesel is reduced maintance,these glow plugs always give trouble at some time,and go bad randomly,then you have an engine that starts hard ,runs rough and smokes bad til they all fire eventually.The controllers go out frequently too,since they pull upwards of 50 amps while heating.I know Ford uses 6 volt glow plugs so they heat up quick,this makes them fail prematurely.The Cummins in the Dodge pickup is the only truck you can hop into and just hit the key,and it starts perfect.It does have a wait light,but its just an air intake preheater,not neccesary,in fact its Dodge spec thing,same engine in a motorhome of freightliner doesnt have it.

Glow plugs are used in diesel engines which were originally designed as gas engines (both the PS and 6.5 have roots as gassers) to heat the air to get going when cold, the real diesels use what amounts to a toaster grid in the intake to heat the air to get it started.
