I am assuming that you are talking about the black plastic coolant pipe that runs under the valve cover on the right side. If so, yes you just need to remove the front bolt and you only need to flex it back about an inch or so with you hand and the valve cover will slide up and past it. I just did this about a month ago. As I mentioned also, I loosened the bolts holding the combi valve to make it easier to have more room to get the valve cover off
