PLEASE GIVE ME much NEEDed ADVISE< 6.4 ps or 6.7 ps

hey everyone i am new to this site but have always been a ford fan.... I currently own a 2006 6.0 ps crew short box, I love this truck, but it has also drained my saving within the last year or so... I am FORSURE going to trade the truck this fall but i am really having a problem deciding what i want... I love the 08-10 body style, but the 6.4 makes me nervous. I love the New 6.7 ps but the body style is still growing on me... the reason i know i love the new 6.7 is because my old man bought one... NOw the reason the 6.4 ps makes me nervous is because i have seen videos and heard of these motors destroying pistons which we all know this means $$$ and new motor, oil coolers and egr valves . What i am looking for is LOOKS, reliability, which i have heard good things about tuned 6.4ps , but doesnt make it perfect...I want to Hear the good and the bad...I have a buddy who works for Alligator Performace who claims he can damn near make a 6.4 bullit proof...What does everyone think!! Thanks guys, love this site

The 6.7 PSD is a totally different animal compared to the 6.4. I loved every second I was in the seat of a 6.7 KR while test driving it. If my 6.4 had more miles on it, I'd trade it in for a new 6.7. Unfortunately, I have less than 25,000 miles on my '09. I think all new diesels equipped with the emissions stuff are problematic and cause concerns about reliability and longevity. This is for all brand, not just Ford. The 6.4 is destroying pistons because of the EGR cooler. These incidents are pretty isolated but have happened. If you like the look of the 6.4 over the 6.7, get the 6.4. The reliability issues with the 6.4 can be eliminated by getting rid of the emissions clogging system. At the very least, get a tuner and EGR delete. I'd recommend that in addition to an intake and exhaust.

I would love to hear what your buddy does to make the 6.4 bullet proof. I have a 2010 f350 cc short box tuned with a black maxx and dpf/cat delete and love it. 24000 and no problems so far.

My buddy claims that with yes a tuner, exhaust, intake, and i don't have all the specifics, but something to do with the high pressure fuel system, maybe the pump, or filters idk for sure, i have heard of a couple instances where the something in the fuel system deteriorated and was ran through the motor, i know the 6.4 are fuel sensitive .... and depending weather i want a egr delete or not having a waste gate turbo, Now i am not a diesel expert by no means and still learning so no offense taken if him or me is wrong
thanks for the replies keep them coming

Don't think the 6.7 is any different then the 6.4 when it comes to contaminates and water in the fuel. That and the emissions and either engine could go at any time.

That said, if you take care of the drive train, i.e. routine maintenance, watching fluid levels, don't abuse it, etc.. either engine will give you many many miles.

Remember, for every post or video where someone had a problem, there are countless others not.

I too test drove a 2011 F350KR and it was awesome. Fortunately, the 2010 F25XLT I bought instead was kinder to the pocketbook and I have no regrets. And a bonus to me on the 2010... No DEF.

I don't mind DEF. It's becoming more common on the OTR trucks that truck stops sell it bulk, right out of a pump. Only thing I don't like about DEF is that it freezes and you go into limp mode if you run out of it while driving. Guess you'll have to keep a bottle of it somewhere in the cab just in case. The cost of DEF is probably pretty close to the amount of diesel saved when our trucks are in regen.

I thought the 2011's have DEF and a DPF... so they would still have regen... DEF is for a totally different reason than the filter....
