Hey all!

Just have a question. I was watching a powerstrokehelp.com video from Bill explaining why the 6.4 has trouble in the long term. He says the particulate filter gets clogged with soot and causes the motor to run hot and eventually blow up. He did suggest getting rid of it.

I know this is the 6.7 forum and thats what I have. From what I see dont we have the same issue in the long run?
Do you think we should delete that filter so the engine can breathe and not let the filter clog?
I really love my 2012 6.7 F350 and want to keep it a long long time with alot of miles.
Just wondering if I will have to get rid of that system to achieve that.

Thanks for your replies in advance!

 

Let's see, voided warranty, up to a $2500 fine and failure to pass inspection would be some reasons I'd consider. For me, I get enough diesel exhaust on my tractor, I don't mind having a truck that doesn't smoke and stink.

 

Thanks for the response but that has nothing to do with my concern.

A new motor is 25 grand so heck yea sounds like a deal to pull it all off.

 

The DPF needs to be replaced eventually, if not cleaned. By law, they're supposed to last 125Kmiles minimum assuming there are no engine problems that cause it to plug up sooner.

Dunno... I only have 42K on my '10 6.4. I pulled off the DPF at 30K and blew out some ash with my blow gun. All still seems good and my regens were spaced about 25-50miles further apart afterwards. I might do it again one of these days.

I think there are plenty of other 6.4 owners who have high mileage and are still running fine. Stop-and-go city driving is what causes most of the problems

 

I do a lot of stop and go in the city. It sounds like taking it off and cleaning it out every once in a while is not a bad idea.

 

I plan on keeping mine for a long time.
I deleted at 5,000 kM.
No regrets and no issues since.
(Had a BUNCH of trouble with CEL etc prior to deleting).

I idle a lot in the winter, no issues (obviously)

Thanks

 

The 6.4L is a 1st generation of DPF, Our 6.7L are 2nd Generation and more efficient. You never hear of Passive regen in the 6.4L world. But it is a common occurance in our trucks.

I'm in the 70,000+ miles on my truck and I'm not seeing my EGTs running any hotter today than they were two years ago when I bought the truck. So I don't suspect that my DPF is getting plugged up yet. Did his video suggest at what temps the extra is causing a problem? Most around town driving never sees the temps we hit climbing a grade while towing. Is he concerned about Regen Temps or just normal driving temps becoming hotter and causing the problems?

Like the other poster, I have to deal with emission and inspections, So removing the DPF is not an option. The few poster that we see with 100,000+ mile trucks have not mentioned DPF problems or even having to replace their filters, So I suspect it is much farther down the wear curve. Maybe we will see folks starting to have common problem and having to deal with replacements at 150,000 -200,000 miles. Who knows?

 

I tow heavy with my 6.4. I have 74K on it. DPF is just fine.

It is the city driving that kills it.

 

And city driving can eventually kill DPF 2.0 also since EGT's can't keep up with stop and go to allow for passive cleaning.
Making sure active regens are completing will help IMHO.

 

I vote for deleting it.

 

Might better delete the EPA

 

Yeah, or at least get them to work to their original charter. However, if you do pull your emissions equipment, you'd better hold on to it. Hard to guess what's in store for us in the near future....

 

Not everyone has that option without paying their state government more money in fines.

 

My DPF was in like new condition at 122,000 but I tow on the interstates all the time. Best possible conditions for it. A city truck would concern me but technically there are no rules when you buy a truck. Just drive it however you want and don't worry about it.

If you want to tune it, just do it.

If you want, run it until it plugs and at 100,000 tune it.

 

Short trip city driving is the culprit! My daily commute is 8-10 miles one way depending on my route. If I go a couple of weeks without doing any highway driving where it can get plenty of passive regen, I start to see very short intervals between active regen (120 miles or less). Throw a couple hundred miles of heavy towing in the mix and all seems well again. I just completed a 1,000 mile round trip to deliver my trade in and pick-up our new fifth wheel and that amount of heavy towing through the mountains made a world of difference in the truck. Since returning home last Saturday, I have driven approximately 100 miles and my soot level has not moved by more than 0.30. The same driving a week ago would have netted me a gain of more than 1.00 and I would probably be looking at an active regen today, but It will likely be at least 200 more miles until the next regen.

My experience so far with this truck tell me that it needs to be run hard even if that costs you a bit of fuel economy. If you do a lot of short trips, you need to do some heavy towing once a month or so to really clean that filter out. A few good mountain climbs with over 13,000 lbs cleans her right out to way less than 0.89 which is unheard of during normal driving!
