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.
