The 6.4L Powerstroke
If you like lots of information on 6.4. It takes some time to load.
6.4L Power Stroke Specs

 

Interesting article. A doom and gloom article in of sorts.

Interesting in that I don't see oil cooler failure as they indicate. I don't see problems with the turbo's either.

Couple other things I do agree with.

Heavy on the maintance side is required.

 

You would think that Ford would fully support 6.4L owners who upgrade the oil coolers and egr coolers, if bullitproof offers a lifetime warranty on these upgraded parts it makes no sense for Ford to keep putting the same stock parts back in when they fail.

 

far as I know not many oil cooler failures, rather rare as far as I can tell.

 

I haven't had the time to go through this article yet, but a couple things stuck out at me. First of all the VGT system on the turbo is an electronically actuated system, not an oil actuated system. There's an actuator motor and electronics that are cooled by the fuel cooler. To be fair it's an easy mistake to make, as the 6.4L is the only engine since 2003 to not use an oil-actuated VGT system.

Secondly, the first category he lists for failure is the oil cooler. Now these are a big deal for the 6.0L, as the oil cooler is plumbed in series with the EGR cooler. Thus a plugged oil cooler can cause the EGR cooler to melt down, leading to hydrolock and engine failure. On the 6.4L this is not the case, as they are plumbed in paralell, so one can't cause the other to fail. I don't remember ever seeing someone come on here with an oil cooler failure, and while I'm not saying it doesn't happen, I'm willing to bet that it's quite rare.

So while there's good information here not everything is exactly correct, which leads me to question the knowledge and accuracy of the rest of the article.

 

Tom,

I agree! I re-read the article again myself today. I would be concerned with these folks working on my truck. There were several discrepencies in the article.

VGT, EGR, Oil Coolers, Injectors. Reason for oil growth.

I suppose early on it would have been a good article of possible issues but it certainly should have been revised very early.

 

I agree with a lot of the article and some I'm not too sure of. But, I feel like I'm reading one of those multi page Cell Tech "Scientiffic Studies" in the old body building magazines. Just one big advertisement.

 

I just read the article and there are a few inaccuracies. What it does reaffirm is these trucks require the owner to stay ontop of the maintenance, and to use genuine Ford parts. I'm not saying that will eliminate all problems, but it doesn't hurt.

 

It struck me as more of an attempt to sell parts via fear.

 

Also read their article and sounds like a sales pitch for there so called bullet proof services.

 

We have a winner

 

I've had 2 oil cooler failures in a row... Just got my truck back 5 days ago.

 

You are not the norm though

 

This time seemed to fix the problem tho, They replaced all kind of other stuff too.

 

This is what I was thinking but needed to hear it from you pro's!
How close are spec.s on 2 web site?
