With cold engine i hear some kind of clicking noise every 5 second or so. But as the engine warms up, the noise goes away. I asked one of my friends, he told me to get the valve adjusted. Does anyone know how to do it? Does it involve lot of work? Anyone with repair manual kind enough to post some points or explain how to do it?
