Good afternoon Davidclio. You were more right than a saint. Today, when I arrived from working, I was going through a workshop to which in Estepona that it turns out to be a friend of my brother who was working in the official Renault house already mounted an own workshop. Total that I went to see it and I told me that that escape is normal in these engines that come out from 65000 km and it is because it has a little loss the seals of the turbo and puts them through this tube that is the admission of the turbo, which does not worry that it is normal. I also told me that this part where Suda does not have a joint (a bit weird not), total that to remove the leak I told me that I first petroleate the engine and then remove this box and put a joint of the joint and buelba to place it, and I look does not balla to be that it has another escape that is not seen. He says that he is too stained who believes he can lose on the other hand. Total a car always has problems. Thank you very much compi for your help I hope not to have been very heavy to another greetings.
