| Does the oil change to black quickly in Diesel engines? I just bought this 04 Dodge and the previous owner said he just changed the oil. I drove it 800 miles home and the oil was black as coal. I changed it and the filter. The oil went black again almost immediately. Is this a concern? Can I clean out the engine? Thanks | |

Thanks kcram. It is an 04.5. So what is my question. Does this mean an HO? Is there a way to get the torque converter to lock up earlier? At low speeds, the engine RPM is way up compared to ground speed. Could save alot of fuel, more like a manual. Was reading about this last night. Is it only available on Fords?

I have an 04 Ram 2500 Cummins with 130k miles. i have recently ran biodiesel in my engine. since i did this, my engine has been idling very rough and vibrating at speed. i have since switched back to petro and i still have the same issue. i have changed the fuel filter twice, but no help. can someone help me on this and give me an idea on what the problem could be?

Replying to: ramcharger (Mar 31, 2009 6:05 am) - 235/460 = California - 250/460 = standard output (2003 only) - 305/555 = high output In January 2004 (2004.5), they were all replaced by one 50-state legal engine rated at 325/600. The TC will not change its lockup pattern unfortunately. For 2005, the calibration was revised and I have different shift points and lock-up speeds than your 2004.5, plus I have Tow/Haul instead of OD-off. (It would be a while before the 48RE was allowed to have both.) You can probably ask a dealer if your transmission software is up to date, although a reflash is not reversible if you don't like what happens afterward. kcram - Pickups/Wagons Host |

My dad has a new cummins and has never had a problem. But he does tow a 35 foot cow trailer a least twice a week which dodge says need to be done with the new cummins or it will clog up the turbo.. If you want to keep it out of the shop tow a heavy trailer or load with it regularly.. If you dont have a trailer or something heavy to make the truck work I would get rid of it like the guy above and get a gas.. I have had a dodge hemi and it pulled my cow trailer full of cows all the time with NO PROBLEMS.. all the power you would need is there in the hemi. I just couldnt deal with the fuel milage or beating on my new truck so i got the cummins. Best truck i have ever driven by far... |
