6.4 powerstroke issues

[GTPpower]

I found this while searching....





I didn't realize they made those with a 6 speed manual option. Looks like it's got some deletes done, but what other problems might pop up?

How about the motor itself? Will it last til 300k miles?

I had a discussion with [MENTION=7923]CTC DEEZUL[/MENTION] about these before, I think they have a valve train issue that dooms them from ever being part of the high mileage club.

 

[GTPpower]

Yeah, that's what I heard...the guy at powerstroke help claims they are shot at 100k. I was wondering how true that was.

 

[DEEZUZ]

Junk. Pass.

 

[GTPpower]

Haha.


Is the motor on it's last legs with that mileage?

This thread is relevant to my interests. Thanks for posting. Is there a fix for the valve train issues - or are they just junk and should be avoided completely (which is what I've heard from multiple sources)?

 

[DEEZUZ]

Junk. Pass.

See here

LOL, I was looking for a few more words to explain your position.

[DEEZUZ]

Lol nick. Yea, maybe later.

 

[boostedguy05]

is this the one where it would be a $10k fuel job, i was looking for the post you made about that.

 

[DEEZUZ]

Yup.

 

[DEEZUZ]

Glad to see someone's paying attention

No problem...us powerstroke idiots have to stick together. Haha.

I get 6.0s, 7.3, 6.6(early), 5.9(VP44) in all the time with bad fuel. drop the tank, flush the lines, change lift pump, maybe injector or 2, but their back on the road most of the time for under $3k.... run a cup of water or gas through a 6.4 or 6.7 and itll be a $10k+ bill

 

[GTPpower]

Thanks!


I know guys that run a little gas in their 6.7's to keep from gelling in the winter. But they have more money than me and usually trade before 100k.

I thought we put holes in the $10k fuel job when it was first suggested... no?

 

[boostedguy05]

seems kinda against the point to put holes in a new fule system

 

[Eagle]

Oh. This guy thinks he's got jokes.

 

[boostedguy05]

couldn't miss a good opening.

Great article with some solutions to deal with the common problems.

Or just run an additive lol. I wouldn't do that on any modern fuel system.

If it was, i didnt see it.

Less Frequent (Yet Notable) Problems

Rocker arms can break under high horsepower and are known to wear severely at the fulcrum ball (age and high mileage seems to cause failure in stock applications, in which the ends wear down due to friction).
Lift pumps can fail prematurely (it’s not just a high-mileage problem) in stock or modified trucks (although tuned engines can kill them faster, as the pump struggles to maintain fuel supply to the injection pump).
All 6.4Ls seem to have considerable blow-by (even 100 percent healthy engines), possibly due to relatively loose ring end gap specs from the factory.
Injector O-ring failure is somewhat common with age.
Catastrophic injector failures aren’t particularly common, but some failing units can stick open, causing oil dilution, and in some cases cause piston damage or even hydro-lock the engine.
Oil coking can plug turbo oil drains in some instances, leading to premature turbo failure.

The 10k rebuttal was in another thread when it was mentioned, I don't recall where or when.
