I drive a 95 Zetec Mystique, I took the car to the shop for a tapping when cold, turned out i needed a new timing belt and pulley. Ok. Well, it still taps, and it doesn't go away. It's not bad, and it doesn't really get any lounder as you g faster, it just increases in frequency. It's not a valve problem, because the car would be seriously messed up. And nobody cna definitively say it's a bad lifter, so, before I spend any more money, I want to take off the timing belt cover, maybe it's hitting it in one spot. Any reason's not to take it/leave it off? And while I go ad grab me tools...what am I looking for? Hehe..my neighbors must love it when I come outside with all my stuff..open the hood...scratch my head for a half hour..pack up my crap and go back inside lol!!! Thanks in advance.
