Hello: I know exactly what you mean by this "ticking" sound. I have a
91 Civic, and I have been living with this ticking/clicking sound for
almost 5 years. But the car runs fine, gives about 40-41 mpg. In fact
if you listen carefully, you can hear it constantly as you cruise down
the highway. It is not the timing belt, nor the lifters. The only time
it went away for me, was after I changed my oxygen sensor....but it
came back to haunt me after about three days. Been with me ever since.
I do not know where the noice comes from, but think it is some
solenoid behind the instrument panel or the fire-wall. I also checked
my fuel injectors, but they were o.k. too. If you peruse old e-mails
in this newsgroup, you will come across occasional postings on this
mystery sound from several others also. If I ever come across the
source for the click/tick I will post it here.
