[QUOTE="TonyCT322, post: 125172, member: 19714"] Same issue on Dad's Ford Diesel Tractor. Replaced the injector pump due to age and sitting. Within two years, was getting fuel in the oil. Replaced fuel pump on the injector pump three times with minimal change. Pulled injector pump and took it to a shop. Insides were completely rotted out. Shop said they could tell it sat more than was used. True, as it only used when I would come to the farm to bush hog the fields 3-4 times a year. Anyways, his advice... move fuel storage tanks inside out of the sun due to condensation; due to the amount of water (ethanol) being added to all fuels, run the tractor weekly for at least 30 minutes so it is not sitting in the pump eating away; use fuel additive or conditioner with every tank. I also started using a couple of ounces of two stroke oil for added lubricity to every other tank of fuel. Following this advice and replacement of the injector pump the problem was resolved. With a "freshly" rebuilt engine, I would look in that direction first. [/QUOTE]
