My '88 5kCST makes this same clicking noise, all the time, cold or hot.
But it is a bit louder when cold. As I step on the accelerator pedal, the
clicks get faster and faster, but I can only really hear it when the door
or window is open.
Maybe this is something common in '88 models? Or I have been told it could
have something to do with the exhaust manifold...oh well, at least the car
runs good. I can live with a little ticking, as long as I am not damaging
anything by not fixing it.
