[Shotimes] SHO Idle Clicking

[Frank & Susan Malinowski]

I have some clicking at idle when warm intermitently.  No problems at speed
or any other time. No problem with CA emmissions.  I have 141K on my 92
MTX. I was planning on holding out to 150K mi for the 60k service. Is this
something I should have checked right away as the engine could destruct in
the near future? Too bad there is no OBD code for idle or rod bearings for
those of us who are more electronicly than mechanically inclined. If it is
wearing in the timing gear what parts do I start looking for?

No knocking, but a "ticking" similar to a bad lifter in a pushrod engine, a
ticking that I couldn't find.

George- you and I had this disease at the same time.  I tried to resurrect
my car for a year, trying everything I and the list could think of.  (In the
mean time I had to suffer by driving my wife's old 94 Cougar.)  You happened
to discover yours before I did.  When you first posted your discovery I went
out and pulled my top timing belt cover, and sure enough....

Anyway, I bought a gear and key from someone else on the list, installed it,
and the car was back to new condition.  The crank was OK.  From the
condition of my gear and key, I estimated that my timing was retarded almost
20 degrees.  This was about the right time for my second 60k so I put in a
new timing belt, water pump, front oil seal and CPS at the same time.
