I recently adjusted the valves on my wife's 93 DX (d15), cause i was doing it on my car anyway and hers has like 190k. I used the specs in my haynes manuel .007-.009 intake, .009-.011 exhaust. I was suprised that it seemed that every single one was under spec, so I opened them all up to be in spec but now the valvetrain noticably louder. I was pretty careful not to open any up to far or not tighten them down far enough so im psoitive thats not it. Anyone ever run into this?
