I was already impressed with the Cummins Engines, but after watching this video you will be like in awe!. They are considered the best diesel engine manufacturer around the entire world and when you see how they do things you should be extremely impressed. There are companies claiming 2,000,000 miles on these babies.
Even if your just a little bit gear head you should like this. Actually, anyone might like it.
