Oil in my water.......

I think i have oil in my water. im about 1600 miles away from my truck but my woman drives it while im gone. she was checking the oil becase it started to leak pretty good. she noticed the over flow talk was realy dark and there was a very dark oil like substance at the bottom of the over flow..... the oil was about a quart low and black not milky what so ever. two things are strange to me first the suposed oil is in the "bottom" of the resivoir..... oil floats on water..... and the engine oil is just fine..... im gunna have her take it to my dad to get a better look im just freakin out i realy dont want to have to do a head gasket. so if anyone has heard of a similar issue let me know.

its just grimm in your cooling system from seal wear and etc. i wouldn't worry about it too much. diesels natually loses some oil via blow-by and turbo of course within reason like 1 quart between oil changes with out any external oil leaks. imo.

why do mods on a truck then worry about break down and repairs? they go hand in hand. looking for a worry free longevity? leave it stock and only do upgrades to problematic components. just my thought. anyway to answer your question oil does not sink.

when oil is in your coolant the oil cooler could be bad....if it were oil it usually would be floating on the top of the coolant in the over flow or in your radiator, maybe there is no coolant in your overflow just oil thats why its at the bottom ....

Not all the time and not always in large amounts (either way)

Pull the valvecover off and see if their is any white scum stuck to it. chances are their will be, and that means headgasket. You dont always get enough water in the oil to make it noticable on the dipstick, but the chit usually sticks to the highest point!

Here is a logical fix..... Don't let your woman drive it! women have a natural tendancy of F!*king up our vehicles. I let NO ONE drive my chit and I have ZERO problems other than your normal wear and tear stuff. I'll bet money your issue is nothing other than crap build up in the bottom of your resivor. No need to worry until you get home to your baby and see for your self.

if you had oil in the cooling system or water in the oil both would result in a milky white substance that would have you cleaning parts for a week.

Oil floats in coolant, so if the stuff is at the bottom of the coolant tank, sounds like you're waaaay overdue for a coolant flush.

IF.... IF it was oil it can be a couple things. Head gasket can cause oil in coolant and coolant in oil. It goes both ways depending on how you blow the gasket.

Also, Cummins engines have a water-to-oil oil cooler. People often forget about this. If that cooler goes bad, you'll have oil in your coolant, coolant in your oil and you head gasket might be perfectly fine.

But sounds like crud if it is sinking in the coolant tank. Get a flush done.
