Few engines attain legendary standing just like the Cummins B-Sequence diesel. It is powered Dodge (and later, Ram) pickup vans for many years, and the 5.9-liter inline-six featured on this current I Do Vehicles video lived a tough life. It got here from a 2006 Dodge Ram 2500 utilized by a roofer, and at 368,000 miles it wasn’t operating very nicely. However it was operating. After seeing the wear and tear and tear on this engine, that is fairly wonderful.
Reality be advised, 368,000 miles is not that a lot for a diesel however it appears the proprietor did not care about repairs. The video opens with a proof that the truck was trashed, inside and outside. It was used for work, and when the proprietor lastly took it to the store for engine issues, the entire truck was deemed too far gone to justify the restore price.
There is not actually a lot to see by means of the primary half of the teardown. The highest finish of the engine seems fairly good contemplating the age and mileage. The primary indicators of hassle come as soon as the pinnacle is pulled, revealing the pistons and higher block. Just a few cylinders have deep grooves within the wall, and bits of particles are discovered within the combustion chambers on the underside of the pinnacle. One thing contained in the engine had clearly busted.
Because the pistons come out, we see a number of damaged gadgets. Piston rings on three of the six pistons have been snapped, rendering these cylinders successfully ineffective. The unhealthy rings scored the cylinder partitions, which in flip scored the pistons. Heavy put on was additionally discovered on the camshaft lobes, rod bearings, and tappets. On the very least, this engine would want reboring and a brand new backside finish to run once more. That’s, to run correctly once more. Even with three busted rings and metallic bouncing round inside, the Cummins fought to the bitter finish.
What brought on the injury? The video factors to a common lack of upkeep because the doubtless perpetrator. That may very well be rare oil adjustments, utilizing a poor high quality oil, or just ignoring smaller issues till they grew to become larger ones. In any case, this engine has towed its final trailer. The cumulative issues are an excessive amount of to warrant a rebuild.
