Just got my 04 civic back from getting a new head gasket and there is a serious knocking coming from up high just under the valve cover. It did not have this knocking before. Before I call the mechanic back, I want to have some ideas of he could have missed or did wrong. (timing off, bent rod) I just dropped a chunk of money and I'm a little nervous. Any help would be greatly appreciated.
