the fix for this is a DPF delete pipe,EGR delete....and a Smarty programmer to make it all work right...... Just bought an 08 taday with a blown up engine at 110k miles because the owner didnt follow precautions

Victoria,

Sorry to hear about your current concerns with your truck? How often does this happen? When was the last time you were at the dealer for diagnostics?

If you'd like additional assistance reviewing your concern I'd be happy to help, just PM me the name of your servicing dealer long with your VIN#.

I look forward to hearing from you.

Bought a 5.9 in 2007!
Traveled to Dave Smith to get it and saved $10,000 including airfare and fuel to get home.

Glad I didn't try to talk the locals down on the 6.7

Last truck I will ever buy.

2008 6.7 is the worst truck I've ever owned. It has been in the shop w/major problems longer than it has been on the road. I wish I had my 5.9 back.

horatio102 01-21-2013 04:45 PM

My 08 was rarely in the shop, except for the time I broke the transmission. Of course, I removed the egr and dpf the week I bought it.

Rescuewiz,

What kind of problems are you having with your Ram? Is there anything outstanding or ongoing at this time? Let me know if you would like any assistance resolving any current concerns.

LOL guess I'm not doing too bad at 13.5-14.5MPG with a 500hp truck...
Sad that stock new engines aren't getting any better in fuel economy.

unless he did DPF, cat, and EGR deletes: definitely not

that's cause you were smart enough to leave the egr/dpf gnomes unattended next to your truck :icon_laugh:

horatio102 01-22-2013 10:09 PM

Yeah, I really liked my 08. The 6-speed auto was pretty nice for towing, and having it use a brain for downshifting and keeping on the exhaust brake was really nice. 15 mpg on my daily commute wasn't bad considering it was a 7500 pound, 500 hp truck.

2011 d-5500
 
friend Jim has a 2011 d-5500 they have changed turbos twice flashed the computer changed injectors numerous codes that show up. now the def has crystals in the system so that is going to be replaced. most of the time it starts in power down mode. what can i do to help Jim? he is past being mad he paid 53,000 for this thing now he never has a truck to use because it is always in the shop.

Jigabop 01-29-2013 11:14 AM

get a DPF/EGR delete programmer, delete the DPF, EGR, and cat, and she'll run like a top.

Sell it if he can. It will be cheaper in the long run. They have never been able to fix mine.

AlaskanRenegade 01-30-2013 12:20 PM

TON of 6.7Ls up on the slope up here in AK were takin dumps faster than a you could flash your brights. rods knockin all sorts of things goin wrong. Sad.
Glad I have a 98.5 5.9L

Jigabop 01-30-2013 01:39 PM

the old 24v's even though they have been given a bad name by people who have not kept proper fuel pressure to the injection pumps, seem to be the only ones reaching mileage worthy of the record books.

there are quite a few 24v vp44 motors running around now with well over 1 million miles on them.. one of them when last checked a few years ago was over 1.7 million miles and counting. I'm sure he is over 2 million miles by now and he still has not had to rebuild the motor or transmission or rear ends..runs synthetic oils in all parts of the truck.

john breeze 01-30-2013 02:42 PM

jim's dodge
 
he had a 05 dropped #5 valve in the engine he was towing 18,000 with so he thought he would up grade to a bigger truck.

ricklane0310 06-17-2013 09:23 PM

I am having trouble with my 07 dodge 3500 6.7 cummins. It quit going down the road.we put a fuel pump in tank and get it running on either drop below 1800 rpm and it dies out. It will run without either above 1800 rpm not below

horatio102 06-18-2013 12:33 AM

Sounds like your EGR, VGT, and/or DPF are clogged.

DodgeCACares 06-18-2013 10:21 AM

Ricklane0310,

Sorry to hear about your concerns. When was the last time you were at a Dodge dealer? Do you know if there are any outstanding recalls for your Ram?

If you'd like me to review this for you feel free to PM me or you check for recalls at the link I've added.

I hope this helps.

Never had a problem with my 07 6.7
 
stock 07 6.7 Cummings with 115k miles and the only thing i replaced is tires and ball joints and of course oil, I do off road in it. I do take it on long road trips hauling big trailers, And i also let it idle for 6-8 hours wile I sleep in it, time to time....even starts up in -25 temp with out being plugged in with no problem

dieselhuffer 06-14-2014 10:57 PM

cant idle for extended periods?
 
I work in the oil field and all our company trucks are ford and dodge 6.7l's. We idle these things all day every day and ive never scene any of these problems described in this thread. We were on a 24 hr job and I **** you not this guy let his idle for 4 days straight. He just kept filling the tank with diesel. Seriously 4 days with a 2012 3500 cummins, then after the job was finished, he drove 5 hrs home at 85 mph and nothing bad happened. I see guys with newer fords idling thru 12 hr days and have yet to see one break down or go into limp mode. I personally have a 02 powerstroke 7.3 and I idle it for about 5 hrs a day when im out at work in 110 degree texas heat , I have 356000 miles on the truck and dont have problems. Maybe we all just have dumb luck, but I think diesels are made to idle( except for the 5.9s) I hear you burn up oil pumps if they go too long.
