OK so i finished the valve/cam cover job and have everything back together. i put a catch can on each valve cover opening and a small filter on the openings that went back into the system. i did notice that when i plugged the hole on the passenger side of the intake manifold my idle dropped slightly. I did an engine swap last year and since then my idle seemed to be slightly high so with the hole plugged it is almost exactly at factory recommendations. should i plug it or put a filter on it to allow air in? sorry, just because i can do an engine swap does not mean i know what all those stupid hoses do. Are there any other hoses etc i can take off for performance? Inspection is not an issue. <img src="/forums/images/graemlins/smile.gif" alt="" />
