Hello all. I am new here and have a big problem on my 07 Ram 3500 6.7 Diesel. I was on a trip back home (dragging a trailer with a big farm tractor) to West Texas from Houston and about 200 miles from home there was a big POP and engine faltered and then recovered.
Then i noticed i had a complete loss of power to accelerate and engine would respond slowly to pushing the accelerator down. It would run ok on flat ground but would not pull up hill very well, speed would drop down to 40 miles MPH. After the uphill, it would very slowly regain speed. Dark black smoke was pouring from exhaust and temp increased just above the midpoint. I then could smell something burning and just blew it off as the oilfields i was passing through.
I then realized that there was a loud exhaust noise under the hood. I stopped at a safe place and opened the hood to discover that the exhaust manifold had blown 1 or more gaskets. The engine exhaust was so hot it had set the oil soaked insulation on fire under the cowling. It was just smoldering and no flame. I put it out with water and my extinguisher and continued driving.
Once i got home i was able to inspect the engine area to see what had happened. I discovered that the connector to the MAF had become disengaged, which i assumed was the trouble maker. However, when i did a test drive i still had no power.
So in summary, the Ram 6.7L has no power on acceleration and blows black smoke and uses about twice as much fuel as normal.
So, does anybody have any idea where i can start to look for whatever is wrong?
Thanks, for any help.
