I had to get the truck out of the road so we unloaded the little Sidekick as quickly as possible and hooked it to the front of the truck with a tow strap. Got out for a quick look and could see lots of diesel under the front of the truck. The truck would not restart and I could smell diesel. I coasted to the edge of the road the best I could but was still blocking much of the north bound side of the highway. A few miles later while approaching Jackpot, the truck died just like you had shut if off. The first indication of a problem was the check engine light came on but the truck continued to appear to run okay. The driving tracks on the road were basically bare but there was lots of packed snow and ice along the edges of the road and in some places in the center of the driving lanes. It was before sunrise on the 2nd of January and were were approaching Jackpot NV near the Idaho/Nevada boarder (middle of no where.) The outside temp was 7 below according to the trucks temp gauge. (she works at a local primary school) We were pulling a car trailer that had our Suzuki Sidekick 4X4 on it that we had used to explore around the desert with on our trip. My wife and I were driving home from our annual Christmas break trip to Arizona. I have a 2007 Dodge 3500 4 door pickup with the Cummins 5.9. I am sure a lot of you are already aware of the issue, but until a few days ago, I was not and if I can help even one person out there I feel this thread is worth it. Also, I am not trying to start a bash on Dodge/Cummins but am only trying to warn others of a recent problem I had with my Dodge that turned out to be a fairly common problem. In addition to not just following the OEM procedures for tightening sequence our assembly technicians record the achieved torque load through use of digital torque wrenches ensuring no fastener will come loose over time.I have seen other threads concerning pickups so figure this one is okay. These engines use many torque to yield fasteners that require bolt “stretch” to maintain adequate clamp loads. DFC considers this practice unacceptable and installs new cast SBI guides in every cylinder head we remanufacture. Instead of just testing old springs and reusing like most remanufacturers DFC installs brand new SBI valve springs that are still tested for proper spring pressure on every cylinder head we remanufacture.Ĭommon industry practice is to check guide clearance and if within specification, not replace. Our Rottler equipment allows us to remanufacture the Cummins engine to tighter than OEM specifications resulting in a longer lasting more efficient engine assembly. By utilizing a high quality silicone we are able to prevent this from occurring.

The front covers on the Cummins engines use a paper gasket that is known to fall inside of the front gear case causing a significant oil loss and expensive repair. Our production engines are typically matched with near identical weight piston and connecting rod assemblies giving our customers a smoother running and quieter engine.

Most companies will re-grind and install used again.Įnsuring every engine is built to the same high quality standards as the next DFC is very strict on what is remanufactured rejecting components that require considerable “restoring” to acceptable specifications. Our engines have oversized SBI valve seats installed with at least 0.008” crush eliminating this from occurring.ĭFC installs new valves from MAHLE/Clevite or SBI in every cylinder head we remanufacture. The factory valve seats were only installed with 0.002”-0.003” crush which can allow them to fall out prematurely causing engine failure. The 2003-2007 model engines come upgraded from DFC with additional piston cooling preventing premature piston erosion of the piston crown from failed injectors. DFC silicones the oil pans instead of using the factory gasket as they are common to compress and start to sweat prematurely.
