I am trying to get rid of an annoying valve tick. I am thinking it is just a problem of old retainer nuts coming loose. I adjusted the valves last night with it running, and it was sounding great when I went to bed. I got up this morning and started her up, and the tick was back! Is it possible for the retainers to back off after just 15 minutes of running? Or should I be looking for another problem? I am going to go ahead and replace all the nuts today and readjust everything just to be sure. The wierd part is, I could shut it off and start it back up again last night, and it was just fine. Any other ideas??? /forums/images/graemlins/dunno.gif
