Hey guys I'm new to the fourm. Now I recently upgraded my pcv set up to a newer pcv valve and the right shaped hoses. My motor has about 12k miles on it. And at first it was at an idle and certain times when going up hills I can hear the valve rattling like it was about to come apart. Ill get pictures later but the only things I haven't done is a smoke test for vacuum leaks and replace the old plastic 4v carb spacer. Any advice? It seems to have changed and got less severe with the dizzy spring and weight change but its still there. Thanks in advance.
