Hello, I have a Ford Transit Tourneo FAF6 BJ 2006. When I was driving I suddenly had power loss. So I stopped bonnet and sprayed everything with oil. Unfortunately, you could not see where the oil came from. On the oil cooler there is no oil at all. Is also a switchcar. What I had thought about. Oil cooler from the inside defective and some hose bursted. I do not know that with a cylinder head gasket the oil splashes around.
