looking at a 6.4
 

hey guys i am not to smart when it comes to diesels and looking at a 08 f 250 has 33000 on is there any issues i need to specify i need to look for or anythang i need to listen or feel for when i test drive it plz help i dont wana buy a problem child. thanks fellas

make sure the fuel filters have been changed no later than 15,000 miles, oil changes I do them every 5,000 miles, & drain the water out of the diesel once a/month:tu:

Make sure it has all the updates if it's a job 1. Most say to just avoid job 1's all together...

Credit for this goes to Dzchey21. I did a little recon work from that other site.

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 recal 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
