Oil in Coolant... Help!

Oil cooler leaking

 

Don't buy it? Can you not see that this is likely going to be several thousand in repairs? Continue looking! Plenty of fish in the sea!

 

Not sure on part code but do have to change oil and coolant and flush coolant my only real concern would be if they are trying to sell for more then that

And how many miles are on the truck if its over 700 you should be getting the truck at price knowing its going to need overhauled soon

 

Run get away from that one! It may be an oil cooler but it could be worse then that! RUN!

 

With no water in the coolant it is most likely an oil cooler as oil pressure is higher than coolant when eng is running. That being said when truck is shut down, till eng cools the pressure is reversed and usually puts a little coolant in oil.
Here is a thought but a gamble. Could have drained coolant down to repair anything in the past, didn't use a clean bucket and reused coolant. I have seen it many times by a so so tech. Gets tired of looking for a pan he don't have to clean and uses the cleanest he can find. Or the oil cooler was repaired but system not flushed clean. A little oil goes a long way here. As you said proceed with caution and hold itb over sellers head, like a pair of dirty socks.

 

You stuck paper into a coolant tank that had oil in it and hoped for anything other than an oil coated peice of paper? Oil floats on water/coolant. Of course the paper was coated. First and last thing the paper touched was oil.

 

Something to think about. That's an 04 so has an egr. Go a year earlier and you have a pre egr engine. Diesel plus egr equals money pit.
