Ok. Me and my dad were compairing the 24v to the common rail 24v side my side. I went and pulled the dipstick for the oil and looked at it and my dad noticed that the oil on the stick has a tinge of green in it. So we were both thinking that anti-freeze was getting into the oil some how. But here is the thing. Oil level is not raising any, oil is does not look a milky color to it, And it does not smell like anti-freeze is in there. So I thought maby there is some diesel getting in there but it does not smell like it is. Plus I am still getting same fuel milage I always have. My anti-freeze looks clean and green no signs of oil in it. Truck runs normal. So this weekend I changed the oil cause it was due for it and put Shell rotella T in it as well as Lucas oil stableizer. Drove it about 200+ miles and checked the oil and its still clean as can be. Oil pressure from the cab gauge runs normally. My dad told me that the oil should of been black by the time I traveled 200 some miles. This is getting me a bit worried about something so if any one has any idea or questions to ask me to help me figure out what going on that would be great. There is no check engine light on. Thanks

i picked up my 2500 cummins after sitting for 2 weeks it started over heating pulled over and oil was commin out of radiator when cold no pressure and it runs fine just gets hot quick

Perhaps your engine oil cooler is leaking into the engine coolant. Engine oil pressure is greater than coolant coolant.

My oil has greenish tint also.... and I use Rottella T.
