Oil in the Diesel of Renault Clio Motor

Dear friends, I tell you that I have the same problem in a Peugeot Partner truck, the oil came out of the water tank, a graphite color paste, also found this paste in the refrigeration ducts. But when you remove the oil from the carter to verify if there was water there, it does not present the most minimal drop of water ...? Also take out the oil cooler and try it by throwing dilute inside the piece to see if I had leaks and nothing, without measuring that I put a hose joining the two outputs and heated the piece to see if steam came out and nothing.
I will thank whoever has found an answer to this problem.
Have everyone a nice day

If you already checked the heat exchanger, with a bridge between the hoses, that is, canceling the exchanger, you have nothing left but the cylinder head.

Hello, I had this theme in a beencinero clio the fault was in the block thread, it was broken, next to this is the duct of the oil rise that goes to the cylinder head. The oil travels through the threads of the bolt and being at the broken to the water These threads its support base is weakened and around them the water is located. I hope my lucky observation serves you.

Hello good morning:
I do not have (too much time) unfortunately but the first thing you should tell us is that the engine carries your "bencinero" and model year.
These data are vital for any consultation.

If it carries oil refrigerator (located between the oil filter and the block), be careful that it is usually the most normal that your problem can be this piece, in all forms .... Motor model and model year.

Hello, you may have the burned butt joint. We would plan to plan and joint
