I have never owned anything other than a Ford vehicle, 3 f150's and most recently the f250 that I write about now. A few years ago I took over a small business in which day to day operations required a heavier duty truck than the f150 that I was running. Naturally I didn't consider anything other than a Ford. After countless hours of searching sites like these and reading the horror stories people were having with the previous model Ford diesels I decided to pony up the extra money for the more reliable 6.7....after all was said and done it would pay for itself by not dumping money in repairs for the previous models, right? WRONG! Here I sit with a 4 year old truck that has 102,000 miles on it and an estimate of $19,000 to have a new motor put in it. Last summer I experienced some engine troubles, occasionally when accelerating from a dead stop the engine felt like it was slipping and the whole truck would shake while it was shifting gears, it happened most often around 40-55 mph, the turbo wouldn't give any boost and the needle on the dash wouldn't budge, etc. The engine light never came on and the diesel tech at my dealership couldn't get the truck to do it while he was in it so after two weeks and multiple trips taking it to the shop I was told to "drive it till it tears up, when the check engine light comes on we'll tow it in and we'll be able to fix it then". Well the light finally came on, a mile and a half before the engine started shaking, making a loud knocking noise and locking up in the middle of the road. Total engine failure...102,000 miles. The truck that I'm making house type payments on, that I rationalized putting that much money into by telling myself that it would be worth it because it would last 10+ years, has let me down and left me on the side of the road with only a fraction of the amount of miles on it that it should have taken me.
