Diesel fuel in coolant????
My name is James Herzner and I am a member from Powerstroke.org. I have an early 1999 F 250 diesel with 280,000 miles on it. I had a question for you. I understand many people with their problems confide in you for answers. I have a question. I have been chasing a problem for a while now and I am getting into a lot of money. I had a problem where the truck bellowed a lot of white smoke and the truck would not start. I had the vehicle towed home and we tested everything for a week and found out that the fuel pump only had 10 psi right after the pump. We found that the fuel filter was black. We replaced the fuel pump and we also dropped the fuel tank and cleaned out the tank. We cleaned off the fuel sending unit and wiped out the bottom of the tank. After replacing the pump and cleaning the tank we replaced the fuel filter and checked the HPOP for oil which it had. The truck finally started and took a while to clean itself out but seemed to run strong. I was driving it home and something did not appear right. I took it to ford and they scanned the system and they said that the # 7 injector was bad and that there was a lot of blow by from the other injectors. I had used a lot of oil recently and thought that made since. What didn't make sense was that I never had a check engine light come on. I figured with a drivability problem the check engine light would come on. They also said that the fuel bowl heater was broken and that I needed to replace the whole housing. That did not sound correct so I found on powerstroke.org that you can just replace the heater itself. I ordered the heater from the International dealer and installed it to save 550.00. I then drove the truck home from my cousins house and the truck ran terrible after it warmed up. At first, it ran fine then after getting warm it felt like it was going to fall apart. It had lost a lot of power and it was hard to pull hills. I made to a friend's house and we ordered the # 7 injector and o-rings to replace on all of the other injectors. Once we got the injector out and removed all of the other injectors, the o-rings did not look to bad but we rep;aced them anyway. We started going back together with everything and when we went to bump the engine over, we noticed that there was coolant coming from one of the coolant lines. Upon my research, all that can be is a cup in the injector sleeve?? Is this true?? How hard is it to check them? Is it a matter of removing the injectors and applying pressure to the cooling system to see it there is coolant leaking into the injector housing?? Is this a hard job to do?? Should I replace all of them while I am in there? I just don't want to put this thing back together and continue to have problems. Any help would be greatly appreciated.
