| | Yes. You could have a bad injector.. I had a car do that. pull it off the road before you clean out your motor. Also check the oil.. | |

| Thanks so far for the info I got from all of you. The shop I usually go to is not a dealership. They said a fuel system wouldn't have the pressure to pump into the cooling system if it were a block crack, head gasket or something along that line. They said that would be white smoke and a bad running engine, which isn't happening. The injector cup sounds like a promising place to look.
Any other thoughts? | |

| | I hope to have the truck in the shop tomorrow. The oil is clean and normal. That's good for me. I will see about the injectors. That sounds like the best possibility I've heard so far. | |

| | Is the shop you go to a diesel specialty shop? Because direct injected diesels run extremely high fuel pressures, much more than gassers. If it were aimed in the right spot, one of those one-in-a-million things, it could conceivably get into the cooling system. | |

| In a diesel you can definitely have it in both directions like Mort mentioned because of the hight pressure a diesel is under. Is your truck a 6.0L? Post over in the diesel forum, and Doc should be along to answer your question, cause he would know for sure.

| Which Doc?
Me, or Docluv?
Diesels run two fuel pumps -
1. a low pressure lift pump that pulls fuel from the tank to the high pressure pump (anywhere from 65 psi in a PSD to 7 psi in a CTD)
2. a high pressure pump to increse the pressure to 21,000 to 25,000 psi
the PSD uses an HPOP - high pressure oil pump, which drives the injectors, compounding the fuel pressures inside the injector. So, the injector has two feeds - fuel and high pressure oil.
I've not heard any circumstances where the high pressure fuel leaks into the cooling system, as the fuel is fed below the oil feed.
hmmm....this is strange.
I'd take it to an International dealership to do a injector contribution test to see if you have a bad injector. | |

| | Hey Dr Speed. I don't know which doc. The loki wolf said to ask the Doc, so I'm asking. This thing is strange for sure. I wold say it is my luck to have a one in a million fluke. I'm going to keep looking and listening for solutions. I will have the shop start at the injectors. The diesel guy at the shop is pretty darn good. | |

| | Hey everyone, I just wanted to let you know that I contacted our local diesel specialty shop. The mechanic said it really sounds like a cracked injector sleeve. He has done a couple of those jobs on Ford's, so he is pretty confident about the diagnosis. He is swamped so my beast is down until next week. He said I can drive it if necessary, just pull the fuel off the coolant each time. All day job next week to replace the sleeves. If it isn't one thing... | |

| sorry im late on this but yes crack injector cups or sleeves will cause fuel to get into coolant .. as was mentioned fuel pressure at that point is 50-65 psi plenty over coolant system prssures to push into coolant. I would highly recomend do all 8 and inspect injectors for signs of contamination IE rusty discoleration on the lower end any that show this should be changed but I have seen guys rerun them and run well
