Thinking of upgrading from the 7.3, just curious. Thanks

 

Id think the last year, usually they work out the bugs/kinks as they go so the later the "better".

 

Diddo that. Ford had 3-4 years to analyze and fix their issues with the 6.4 system. But don't let that prevent you from taking advantage of a low mileage 08-09. There were lots of TSB's on these systems that could have been fixed in earlier models. There are several posts here listing specifics to look for when buying a 6.4. Most importantly is maintenance records.

 

personally I agree with the above advice but I would look at a job 3 2008 model as a real contender.

Anything after March 08.

 

I don't which is best, but my '08 job1 works just fine.

 

Which mechanical part/parts did they upgrade on any 2010 6.4 engine that the 2008 didn't have?

 

Just a newer style degas bottle and all the recalls up to this point is all...

Recall items like a fuel tank bracket, venturi T

Some of the early ones had some injector problems and wiring harness for the hpfp.

That is all that I can recall at the moment.

 

I think they changed the DPF filter some time during the '08 models. Not sure what was the difference though.

If anything, the list of TSB's for a given model year is a very good indication. I avoid buying first year models no matter how tempting it is :-)

 

I'm somewhat kicking myself in the a$$ for that. I bought the 2010 6.4 partially on that thought, other was financial incentives. But it looks like the 2011 6.7 may have been the exception to that rule.

 

Most important in my eyes was the PCM/ECM/TCM firmware. Early models were shooting flames out of the tailpipe during regen.

 

Isn't that a minor fix with a 20 minute reflash? And that flame out the tailpipe sensation on youtube was rarer then hens teeth. The 6.4 had very little hardware mechaical changes from 2008-2010 unlike the 6.0 that had water pump, turbo, heads, egr valves, egr coolers, icp sensor locations, fuel injector, glowplugs, pistons, etc.

 

Are you sure that's an upgrade?

 

I wouldn't be so sure of that. Alot of tranny issues and cel issues, turbo's that wine.

 

My biggest, if not only, complaint about these rigs is the stupid DPF and the stupid regens. OMG it's such an annoyance. Other than that, I've had a few quirks worked out under warranty and the truck has been great..

Our DPF system is considered rev1. The 6.7 is rev2 and from all I can see, it's become a non-issue for most folks.

My 3/36 is coming up in less than 2.5Kmiles and I have to fix the blend door pretty quickly. The truck is catching up with my wife's Lexus in terms of going into the shop!

I have a bad habit of keeping my cars forever. The shortest was my wife's 10yo Honda Accord only because its tranny crapped out prematurely. I was just saying to myself earlier I'll probably trade-up my SD sooner than that

 

LOL, i know its not as for as reliability is concerned!!! just kinda bored with it i guess. Truck only has 55000 miles.
