Was checking my oil today and it seemed kinda high so I decided to change it. It has been 2500miles since last changed. I changed the oil and got 3.25 gallons out of it. So it had an extra 3 quarts of diesel in the oil. I have always watched the oil pressure and it has been running almost 80 on cold startup and around 55 when up to temp. I checked the balancing rates with the Predator, #1 was between 2.73-2.3 the rest were all 1.5 or less. So none of them are really out. So I am not sure if its an injector or what. Tell me what you think. Eric are ya busy? Might be headin your way now. Oh, since I know you guys will ask, I do not have added filtration, completely stock fuel system. Also 79,700 miles.

No good.


IIRC, the injector return lines can add fuel to the oil if they take a dump. Im not sure if this can be seen via injector balance rate difference.


Take the truck to the dealer ASAP. Better yet, have them come and tow it.

thanks for replying, Well i changed the oil and drove it home from work, it carried about 75 psi pressure with the new oil, I will check it in the morning and make sure it doesnt have fuel in it. I dont know if this is a constant leak, may be because of the maximizer, but I havent ran it very much at all. Do you know of any good dealers around Indianapolis. Or else Im going to take it to Eric.
