6.4 a problem engine?

[zingpow]

So did the 6.4 have a lot of problems? I didnt think so but it seems like a lot of people say they did/do? Maybe they are just saying that because of the bs the 6.0 went through? Can anyone give me some real incite on this please?

I have an 08 job 3 and have had no issues, it has been tuned with SPARTAN since 400 miles, I have run and use the 210 for towing 15,000# 5th wheel and use the 250 for a daily driver, runs "PERFECT", very happy with the 6.4 so much that I will not be going to the 6.7 when they hit the lots.

The biggest ongoing concern with the 6.4 is the fuel mileage and regen. Tuning can take care of both of those issues. I too run the Spartan setup and love this truck. Mine is an 09 with zero problems.

They started making 2008's in early 2007. The first ones were just called "2008's". Then they made a few changes mid-year, and called them "Job 2's". From then on, the early 2008's were dubbed "Job 1's". Later they changed even more things, and they called the new trucks "Job 3's".

From 2009 onward, I believe they dropped the Job-designation, and just went with model years.

The changes were minor. They added some tire pressure monitoring (yay... ) and new calibrations on the computers, better transmission control modules (TCM's), and some other minor stuff.

I think my two '08 trucks were built in January '07 (F450) and March '07 (F350). Both Job 1's. Job 2 started some where near August '07, and Job 3 started near 2008.

A lot of people mistake the 6.4 for the 6.0. I am all the time telling them they are two different motors and the 6.4 is a great engine. Thats why I bought the second one.

Great trucks. Just learn about them before make changes so you are educated. Computers control everything and tuners change parameters computer wants to see so mods we make on our trucks work.
