im hopefully gonna be getting into a diesel by about this time next year and was wanting a 2500 with the 6.7 six speed manual, but ive talked to alot of the customers where i work (tractor supply) and just this past week talked to 2 seperate people who had 07 6.7s and chrysler had to buy them back from them because of the problems. and another person who said his buddy had one that had been nothing but trouble. so should i just go ahead and go with the 5.9 and just get a 5 speed or have yall been happy with your 6.7s for the most part? and what are the real numbers on the 6.7? at first i thought it was supposed to be 350/650, but now the numbers ive been seeing are like 305/610. the 5.9 was more powerful than that. also is this going to be the last year the 5.9 is available or will they continue to offer it along with the 6.7? thanks for the help.

 

I have had my 6.7L about seven weeks now and put about 2,500 miles on the clock. It's my first diesel, although I have driven some diesel trucks and buses years ago. I have not really had any problems with the engine. I love the smoothness and power. Dodge rates the engines differently, depending on which transmission you get. The auto is 360/650, the manual is 350/610.

I am doing a beta test for the Edge Juice with Attitude, which means that Edge sold me one of the first units for the 6.7L at a big discount in exchange for feedback from me. One thing that is interesting is how often the engine goes into "regeneration" mode to clear out the particulate filter. Before I installed the Attitude monitor I had no way of knowing when it regenerates. Mine regenerates about every 60 miles, and the cycle lasts about 12 minutes. To regenerate the engine computer adds a lateinjection event, making the exhaust very rich. This extra fuel burns in the diesel oxidation catalyst, which raises the exhaust temp big time. This heat helps to "cook off" the accumulated stuff in the particulate filter.

If you do a lot of stop and go driving, you will interrupt the regeneration cycle. It apparently can't regenerate during idle. If you don't get a good regeneration cycle once in awhile, you will have problems with the emissions equipment. These problems are covered under warranty (100K miles, I think), but obviously it's a hassle to bring your truck in for service.

I don't know how many of our 6.7L guys in the forum have removed the onerous emissions equipment. If you do, you'll probably have to reinstall the exhaust pressure sensors to keep the computer from throwing codes. I plan to keep the emissions stuff in place unless it becomes a big hassle. It is tempting to remove all that stuff and just put in an Aero 4040XL and some stainless tubing.

By the way, as far as I know Cummins stopped producing the 5.9L for Dodge vehicles back in December. They changed the assembly line and started cranking out 6.7L engines sometime in January. Any 5.9L Rams out there have been sitting on the lot for a few months, so the supply is dwindling every day.

Good luck with your choice.

 

Love my 6.7 MegaNormous! It's my first diesel although I have driven some in the past... it's the first one I have owned.

Power is really nice, it runs smooth, sux gas out of the tank like a hungry teenager but I expect that to change after break in (how long is break in anyway?) and the A/C sux *** but I love the truck so I must take the bad with the good!

I will never go back to the yugo... I like the fact that one tire is bigger than a yugo! HAHAHAHAA.... holy hell i need sleep! Damn kids!

 

break in. . .that could be as much as 100,000 miles. . .however a good wear in period would be around 20-30K
