Looking at a new boat hauler
 

Anyone know of any problems with the 6.7L Cummins Diesel? I'm looking at a truck with 13K miles on it and just want to make sure there are no issues with that engine.

The 5.9 is basically a bored and stroked 5.9 so in that regard it's pretty much bulletproof. The only gripes I hear are about the DPF and EGR systems which have really hurt fuel mileage. We just have to hope that the engineers can come up with better solutions to the emissions problem than those two.

Check these forums out. If there are any other gripes they'll be covered here;

I see 20-22mpg non-towing hwy mileage with my 2006 5.9. There's almost no hope a 6.7 will ever match those numbers. If I had a 6.7 I would put a vegetable oil fuel system on it to reduce fuel costs. There is a Golden Fuel Systems installer in Houston. Give Bud a call and discuss it;

You don't need that much truck to haul around a 20' scarab and a baby:evilb:

Just making sure I don't have to upgrade both when the new boat comes,whenever that is:coolcowboy:

Patrick, I have that engine in my '07 Dodge 2500 4x4. Very solid, good running, powerful engine. Has a built in exhaust brake and tow mode in the tranny. Pulls my 12k lbs. Fountain with no problems. I am going on 90K. Run it at 80 with the boat and trailer and get 11-12 mpg. I get 17-18 around town.It has gone to Destin several times and a couple of times to Lake Travis. The only problem as Cat said is with the smoke/soot cannister in the pollution system. I spend a lot of time on the highway so it really does not affect mine, but if you run them in the city and they never get a chance to burn off or regenerate, it will tell you to go run it on the highway to get it to clean itself. I have had it in the dealer several times for updates to the ecm and to clean out the O2 sensor. All have been covered under warranty and the only thing it has affected is the check engine light comes on. Since the last trip to the dealer for the updates I have had no problems. It is also quite a bit quieter than the Ford's or Chevy's. The dealer/service manager said to have all of that system removed when I get out of warranty and put a chip in it and the fuel mileage will go up quit a bit. Any other questions, let me know. I am very happy with my truck.

Thanks Gerrit. I have been reading up on everything and it seems everyone says to do the deletes.Also the other was about the turbo. This truck only has 13K miles on it so I don't think I will do anything that would void the warranty just yet:evilb: The numbers look good so I think I will pull the trigger in the morning.

how come you didn't make the Conroe run this past weekend?? You afraid of fresh water??

Too lazy to pull the boat out and put it on the trailer. :eek:Actually my daughter is getting married next month. She lives on Oahu Hawaii. Very expensive. We have been kind of laying low on expenses. My wife lost her job about 6 months ago and she has just started back to work. I heard it was a good one. My buddy took second in the Calcutta. His boat was Service Me, a 42' Fountain.

They replaced my turbo before I had 20K on it. The original turbos had too close a tolerances on the vanes and this was more of a recall on certain trucks. Mine never went out nor did it have any problems. Most of these problems were caused by Dodge trying to comply with upcoming pollution regs that will go into effect in 2010. All of the truck builders have had trouble with the pollution systems. I guess they havn't worked out all of the details. I did buy an extended warranty to 100K for the balance of the truck.

I am a little torn right now. I talked to a diesel mechanic that I trust and he told me to run:eek: He said they are having problems with the cat,turbo and exhaust brake. Told me he has several customers that have their truck in for these items every few months. I guess I need to do more research/It's just a hard deal to pass up.

Do you have the exhaust brake?

Dude, check out www.cumminsforum.com I am a member there. They have a section that is dedicated to the truck you are talking about and they talk about the good and the bad. Spend 30 minutes there and all your questions will be answered.

Been there all today reading. Seems like everyone says to do the delete or unplug the EGR. Won't the delete void the warranty? I can't afford to have my truck in the shop all the time and sure as hell can't afford to void my warranty and have a turbo go out.

I can only give you my experiences with the truck. It has been in the shop for the smog program updates and to replace the turbo under warranty. It was replaced by the dealer as a recall not because of any issues that I had. Other than that no problems. I have friends with Fords and Chevy diesels that have had just as much or more problems, and more major problems including trans and pollution problems than any I have had. The truck has 90K and it is still very solid, no rattles, and drives excellent. I just replaced the tires and front brakes at 85K.
I have not done the delete or unplugged the egr.

i'm not sure I would do that vegetable oil deal...

I have an 08 3500 laramie. I love the truck but have had my issues.

Pros: 1.) pulls my 36' apache better than my 05 3500 did (be sure to put a titan 18k lb hitch on)
2.) Exhaust brake is great because I tow with it everyday
3.) Nice turning radius and overall easy to maneuver in the city
4.) Love the bells and whistles (nav., sunroof, pop out step ups etc.)
5.) Don't have to clean exhaust soot off of back bumper or front of boat after a long haul.

Cons: 1.) Fuel economy
2.) Warranty issues (turbo replaced @ 10,000 miles, had a transmission leak, dash shield recall, currently have a brake fluid leak that have not wasted a day to mess with at dealer yet


Great truck and I am looking forward to getting out of warranty so I can do the deletes. When my turbo started throwing codes every day I was glad I had a warranty even if it did take them a week to fix it and I had rent a truck because my rental vehicle was an F***in mini van.

Lastly, I can tell in my truck that if it wasn't for the regens that my fuel economy pulling utility trailers around town would be more like 18-19mpg rather thatn the 13-14mpg that I am getting. If you watch the overhead lie-ometer you can see the fuel economy hit the crapper when the regen process kicks in. I am up to 19,000miles now and it appears the fuel economy has improved slightly as most diesels do.

Thanks Gerrit. I guess I am just reading to much ****.:coolcowboy:

If you decide to pass, let me know about it. I've been kicking around the idea of getting a new tow rig.

My white 2006 dually is for sale. 62,000 miles, never a problem with anything on it. Motor is stock except for True Flow air filter system and Fluidampr. 3.73 rear end and 6speed G56 manual transmission. 2wd. am/fm/cd/sirius, LineX bedliner, Popup gooseneck hitch, 5th wheel mounting rails available n/c.

I don't know anyone that has one of those engines that likes it. Great power, but they are always in the shop for emissions, or they won't run right. Soemthing like that. It isn't the mechanical parts, it has something to do with the emissions (rap. Buy an 04 with low miles. That was the last year of the bulletproof truck. Get the first generatio HO engine. The late production model o4's made more power, but the milage was on it's way down.

If you decide to get it, make sure it has a good warranty.

Remember that I sold these turds for 3 years right around the time that they started screwing them up. Can't go wrong with a low milage early production 2004. :drink:

Good luck

You know me and I love my truck and motor......:asskiss:

You only love it after you modified it and took all the emissions **** off of it. :hitfan:

Well I went a diffrent route and should be picking up my 09 Hemi with 3.92 gears in the morning. I figure the 9K tow rating will be enough for me now and in the future. The ride was 500 times better than the 2500 and the crew cab is oh so sweet.

Wade if you want to know about the 2500 give Tbone or I a call.

My dad's has 3:92 gears and the milage sucks. Go with the 3:55 if they still offer it. It won't affect the towing/

Congrats on the new rig. Did you get 4x4?

You have to have the right setup and you have to talk to restaurants and ask if you can have their used oil. Asian restaurants have the best oil.

no 4x4:picard1: The 3.55 has a tow rating of 6800 i think and the 3.92 is 8600. If I was worried about gas i would buy a prius:flag:
