How old are your primary O2 sensors?

UPDATE: I've driven several 30+ minute trips and a few shorter ones over the past two days and no CEL!!! The last SMOG readiness parameter set this afternoon and I did a 40 minute drive home after that and no CEL or codes of any kind! I am going straight to the SMOG station tomorrow, this might actually be fixed. It seemed like there might have still been a air leak when I sprayed but maybe it was so slight as to not count. The intake manifold and pipes were loaded with oil gunk and I only cleaned what I could see on the outside. At some point I will have to do it again and take the whole thing apart and clean the crap out of it and JBWeld the corrosion I'm sure is in there given that little spot that has started on the outside in the picture I posted.

Thanks everyone! I hope I am not back tomorrow saying the CEL came on...
