Hello Honda Gods and Godesses!

I seek your help once again!

Drove from San Diego, CA to Grants Pass, OR and back (about 1700 miles) over this past holiday weekend. About 140 miles away from our first destination the check engine light came on. Got the little test done at AutoZone to figure out that it was the oxygen sensor in bank 1- the printout reads that it's the heater circuit oxygen sensor.

So we got under the hood and removed the 'cover' that was hindering us from being able to get the O2 sensor out to replace it- and low and behold the part where the sensor is screwed into has a big 'ol fat crack in it.

I believe, from doing my research, the this part is the catalytic converter. It's big... and it looks expensive to replace.

My questions are these:

1) do you think the O2 sensor is actually damaged? or did the check engine light come on because that part I think is the catalytic converter cracked?

2) if in fact it is the catalytic converter... are they expensive? are they a pain to replace?

3) if it's NOT the catalytic converter... what is it? and is it expensive/pain to replace?

4) If I replace the O2 sensor back into the cracked part... will the sensor still work properly? properly enough to allow me a pass on a smog test?

5) How long is it 'safe' to drive this car with an alleged cracked catalytic converter and a bum O2 sensor?

Any and all information that even semi relates to this would be VERY MUCH appreciated.

I have a guy who works on Honda's who can probably do some work pretty cheep for me- but if this is something that's going to cost me more than $200-$300 I need to start savin!

Read i nfo on prior O2 Sensor. Have the same problem but would like to know how to tell if the catalytic converter is cracked. I know very little and don't want to get taken by repairs. Any help would be appretiated. Thanks, Gypsy
