I know the common rail started in 2003. Was this a spit year or was all 2003 models a common rail. THanks for you input.

 

All models in 2003

 

Does anyone remember the first month they saw a new gen dodge? i can't remember now. i thought they looked funny and seemed too quiet. but i like them now
I remember the 1st 24V truck i saw though. it was at a spring fair trade show thats always held the end of march. id heard of them, but my necked kinda jerked when i noticed the new writing under the 'ram 3500" (it was a white duelly ) so i take it that when people say '98.5' that means the first half were made 12 valve? since obviously they were out the 1st 1/4 of the year.
also ive always wondered if they went to the black valve colver with the HO Cummins? i always thought they looked better red. and is it just me or are they earlier 24Vs quieter? seems like the newest one really have a sharp engine crackle. or do they get quieter over time?
Seems like most vehicles are made in the last 3 months of the year before(our 3 trucks are) do they make as many in the new year?

 

2001 Duramax!. I think they got us on that one.

 

Isuzu 4JX1 4 cyl. diesel. 1998 model year if I remember correctly. Holden/Isuzu used it a lot in Australia and as you may be aware Holden and GM are tight. I remember going to GM/Isuzu school in Tarrytown NY when the 4HE1 came out and it was cutting edge technology.

 

HoldenIsuzu. Your right. I didn't realize Holden/Isuzu came out with a common rail that early. Learn something new everyday.

 

Bosch started development in the mid 1990's, and first released it in 1997. First production application was that 4JX1 4 cylinder Isuzu.

The early prototype duramax's (8GF1 is the Isuzu in-house designation for the dmax) were first built in late 1997/early 1998, so it was natural for Isuzu to chose high pressure common rail as the injection system of choice on the duramax.
