I heard that once too, but when mine broke a few months ago I learned
difforent. I took it in to one less reputable shop and they told me
that there was a good chance of the valves being bent. I decided it
might be a better idea to take it to the dealership; they told me that I
didn't have to replace them because it broke when I was starting the car,
not when I was driveing... So, if you were driveing at the time, you might
want to have it looked at, but if you were like me and went out one day
and it wouldn't start because of the timeing belt, you probably don't have
to worry about bent valves. By the way I save around 3-400 dollars
going to the dealership and finding out about the valves (and the car runs
great).

My
son just picked up an 87 CRX , the timming belt is broken. I have heard
the once the timming belt is gone that the valves need to be replaced
also. Any truth to this?

The
need to replace the valves is usually because they get damaged (i.e. bent)
when the belt snaps. However, there are rare occasions where the
belt goes and the valves are OK. But chances are good that you will
need to replace at least one of the valves.
There is also the
possibility of piston damage caused by the valve. In a past
non-Honda car that I use to have (a Fiat - DOHC engine), a snapped belt
not only took out a couple of my exhaust valves but it managed to punch
one of my intake valves through the top of the piston head.
If you
have a bent valve, I would highly recommend investing some extra money and
just replace all of the valves and springs (basically doing a very minor
cylinder head overhaul).
I would also highly recommend that you
replace the water pump when you do the timing belt. They don't cost
all that much. I paid around $35 (US) - after core - new from my
local AutoZone when I did my timing belt. This is also a good time
to replace the thermostat since you have to drain the coolant
anyway. Same with any of the radiator hoses and belts.
In
conclusion .. if you're lucky and it's only the belt that needs to be
replaced (no bent valves), expect to pay around $30 to $50 for a belt and
it should take no more than 2 hours of labor. If you plan to do this
yourself, be sure to get a decent repair manual such as the Helm (http://www.helminc.com), Chilton, Haynes or
Clymer. Even if you don't plan to do the repair yourself, it's still
a good idea to have a couple of good service/repair manuals in your
personal library.
