I'm looking at a Cascadia, mid roof, 505hp, dd15, it has 877,000 kms or 544,000 miles. I like the truck, its from a mid size fleet, mostly deck work. Runs great, I'm going to do an oil sample and maybe a dyno with blow by if they will let me bring it down here. Questions are; What should I be looking for? How real Are the oil pump issues? If I do it, what is the best software I can get? I don't regional now, no more than 4-5 hrs from home and my shop. "Modifying" it isn't out of the question if it became a problem child.
I have 2020 also. Bought it with 419,000 miles. These are the Cascadia 126 model or the "New Cascadia" I don't think these have the oil pump problem. That was the Cascadia 125's. When they came out with the 126, they fixed all the problems of the 125's. The 126's ride like a car and are quiet. They consolidated the fuse panel and all the modules to inside the cab. Some 125's wouldn't start after a truck wash because the fuse panel would get wet and that's why you don't hear about anyone stealing the CPC module out of a 126 model.
