Here is the reply I got:

I think I have a 8.2 injector around here to verify that although they have a control rack and look somewhat like but smaller than a 2 stroke injector,they don't have the fuel jumper lines between the head and injector . So they have O rings on the body like the Cummins used [from the 250 on up ] . With the failure of the upper O ring the fuel would come up over the top and dilute the oil .

Sounds like it's running PERFECT.......................LMAO!!!!!!

I'm sure more then one of us can help you get it fixed up. I'm no DD expert, but everyone talks about the drain tubes and if it gets plugged will pump oil big time and smoke. Something to start with.

The 8.2 does not have a air box so it dont have the drain tubes like he was speaking of. To find the fuel in the oil you need to put dye in the fuel and run then pull valve covers and use black light. Other wise it is in most cases hard to find. Look at it this way a drop of fuel ever 5 min is not bad enough to see dripping but bad enough in a day of running to delute the oil and do damage to the brgs.Another common place for the fuel to get in the oil is the fuel pump seal. When some one uses a hand pump to build pressure from the primary filter to get fuel to the pump this can happen if too much pressure is applied.I have seen it many times.I saw it happen two times in one day to the same truck.All so the injectors can leak from inside plus the o/rings on the injector to the head.
