I had one of my buddies come over this past weekend and help me adjust my valves. This was the first time that I had personally did it and everything went pretty smooth. My friend kept telling me to make sure that I kept the valves tight and did not gap them to far. I checked them several times before I put the cover back on the engine and everything seemed fine. However now I have a light ticking coming from the engine. What will this do to my engine if I just let it tighten back up by itself? I would be concerned if I thought they were way off but I know they aren't.
