I have been looking for an oil leak all day and I think I have pinpointed it to an intake hose that connects either to the turbo or the egr valve by the back of the fire wall. I can see where there is fresh oil on the hose but I dont see where its leaking on the metal part which I think is the egr valve? I inspected the egr metal plumbing and there are no leaks there. Im fairly confident the leak is around the are of the intake house. Any ideas, does that valve tend to leak? If so what can I do because I dont even know where to start.
