i was looking at my engine bay today and found 2 hoses coming out of the valve cover. the top one is a bigger hose and the bottom is the small one. my problem is i saw the bottom one (smaller) is completely destroyed and i want to know if this would be a problem or can i just keep on driving like this? also what is the function of this hose and what does it transfer like air or oil?
this is a photo i found that shows the exact place i am talking about. i am talking about the lower one.
