So I'm looking at getting a 6.4 to replace my daily driver (2002 3500 with a utility box). I've looked at a few and will be getting serious as soon as I get back to Colorado with some time. Can anyone tell me anything specific to check on a 6.4? Any year better than the next?
Appreciate any info.

Check for the normal things fluid levels oil level trans fluid level and blow by out of the oil fill, coolant level and color. Check to see if the truck has any fluid leaks trans engine diff etc also check to see if the dealer/owner has any service records on the truck if you are buying it from a ford dealer see if you can get a oasis report from the dealer. That will tell you all the past warranty work down on the truck (if any). See if the truck has any odd noises while driving down the road and or idling watch how the trans shifts etc and see if the CEL or any warning lights are on. Check the build date on the door jamb Job 1's are most likely to blow the HG's and have "more problems then later builds". Job 1's also have the smaller front bumper valance. Here's a list on the changes from job 1,2 and 3. (I got from another thread)
"Job 1
Build dates 01-07 thru 06-07
First builds of the 08's. Lower valence in front on front bumper much shorter than later job builds.
Radiators would leak, most should be replaced under warranty by now. Also there was a recall for a venturi T to be added to keep the radiators from splitting.
TCM, early on it was thought that the transmission control module was a hold up for transmission life, but has sense been fixed by more refined trans tuning
Transmissions,Job 1 was the only model to have an external filter as well as the internal in the pan. some hard part differences like overdrive planetarys but i dont know all the details so hopefully someone can step in a clarify the changes.
Injectors had a recall for hanging open and filling the crankcase full of fuel, VIN specific recall
Job 2
Build dates 07-07 thru 12-07
Second build batches of the 08 model year
Got a bigger valence on the front bumper, said to improve mileage by 1-2 mpg.
TCM part numbers changed. Other small changes were made hopefully more can chime in with more info
Job 3 pretty much anything built in 08 was a job 3
not familiar with all the changes
2009
2009 Job 2 added SYNC.
Last year of 3.73 gears as an option
2010s
3.55s were the highest gear ration selection"
Someone else will chime in with more info.
