Folks, Can anyone shed some light on this situation? I have an '88 528e with about 97K miles. The valves sound like they are beginning to make a clicking noise. I've talked breifly with some other 528e owners, and they all appear to be having similar problems. Has anyone experienced this before? If so, please indicate the solution that you implemented. Thanks, Vince Sbarra vinces@domain.elided 1988 528e (sorry I'll get the VIN for my next question!)
