Greetings! I have a question about a small hose on my 2009 Accord EX I-4. There is small oily gunk accumulating around that area (picture posted with a red arrow indicating the hose). I've taken my car to the Honda dealer because of this same issue and the dealer replaced the hose clap. A year later, the oily gunk is back. What is the function of this hose? Just curious. Of course, this small hose will be replaced now. Thank you in advance.
