i've been seeing alot of 08 and 09 trucks with 6.4s at the salvage auctions, and they're listed as "mechanical" for the damage.they all have no body damage and the motor intact but most have the motor cover removed. i'm not familiar with the 6.4 and don't follow this forum, so what's the problem with these trucks/motors.thanks, and let me know if anybody wants one

 

Please define the terms "alot" and "motor cover". My 6.4 has had a few minor issues, but nothing to fret big time about. To do any kind of major work on this engine, the cab needs to be lifted from the chassis.

 

My bad on the "motor cover", i thought there was a plastic cover on top of the motor,and i've seen that there isn't. There were only 7 or 8 out of 104 nationally available that had mechanical damage, that just seemed like "alot" to me to start popping up recently.

 

Thanks for the explanation. Even if you just consider the ones available, 104, and there are 7 or 8 with mechanical damage, that would still equal an A if it was a test in the school I went to. Add to that, all the others that aren't available, we're liekly talking a strong A+. Maybe that gives it a slightly different perspective?

 

i know. i was just wondering about if there was a common problem you could plan on having to fix in these motors. i have bought several 6.0s with "mechanical" damage, and they have all had head/egr problems that were fixed with head gaskets, studs, egr deletes, etc.. i was just wondering if there was a similar situation with the 6.4s.

 

pistons melt down, that's $20,000+ repair. fuel system rebuild from failed hpp thats $10-14k depenfing on how the truck is eqipied and what parts are needed.
hpp lock up and strip crank, cam and pump gears that $17-20k+

thats just some of what I have seen.

 

These are high maintenance trucks. Very sensative to oil type, fuel type, maintenance intervals, fuel additives, etc. Thank your EPA man by kicking him in the balz the next time you see him.
Every engine has war stories but for the most part these trucks seem to have emissions related problems with EGR coolers, EGR valves, cracked DPF's, and a little less common are failed fuel pumps. Radiator replacement seems to be like a maintenance item for some trucks as well, others dont have any issues at all.

 

failed high pressure fuel pump are not that uncommon

 

cheezit, would there be obvious symptoms from a failed fuel system pump, like rough running, poor performance, etc., or could one fail just enough that it would still run ok enough to allow enough time to do serious damage? Also, isnt this a part that would be covered under the engine warranty for those under 60k?

 

all the ones that we have seen (14 in 3 months is my count) have either had just a lack of power or will set p0088,p0087,p2291,p003,p0004 codes (some or all of the dtc's)

Warranty coverage is questionable on failed pumps. The leading cause of failer is water in fuel, In no way did ford go out and dump water in your fuel tank so that makes it damage by external forces and not covered. The sad part here is how little water it takes.
We have been getting inspectors taking fuel samples latly and all have failed lab tests.

 

Isnt the water separator supposed to prevent this? Couldnt one make the argument that the separator didnt do its job, thus allowing the water to enter the pump?

I wonder if Blackstone tests fuel? Its a shame that we have to do these sorts of things to protect ourselves but I guess it is what it is. I havent cruised the Duramax or Cummins sites in a while but I would like to know what the comparison is looking like these days.

 

Dont have cheezit's expertise, but if I were to guess it seems to me that Ford would have to prove that there was negligence in not changing the fuel filters or that water was too abundant in the HFCM which hadn't been drained to deny the warranty. At least thats what they would have to do for me to not b*#^*. Their filters, if changed properly, should prevent this, and if mine went out, and Ive changed mine religiously, they had better have a good argument against warranting it. Youre right, the filters, in my opinion, should stop this if the owner does his part and drains the filter and changes them.
