Are you talking Air Fuel Ratio Meter?  If so then yes.

Just nothing lasts forever.  Trying to survive in an exhuast stream
is a terribly rough life.  With the impurities in the fuel, atmospheric
conditions, you would be hard pressed to invision every possible
contamient.

>Are O2 readings good enough indication of how engine is running?

If you talking about a oem 1-2-3-4 wire one, you'll eventually melt a motor
down.  Things are worth doing right, or not bothering with at all.  If ya
wanna get by with playing games, fine, but there are
penalties for cutting corners.
