Sorry to open up this can of worms again, but I can't remember if there was
ever a final conclusion...

Is the O2 sensor supposed to replaced as part of regular maintenance and if
so, how often?


Also, let's talk about causes for white smoke. Not thick and bellowing but
visible from behind during heavy acceleration from by high mileage 302HO. I
was told by a friend that it is frequently caused by valve seals. I thought
that leaking valve seals was mostly evident during starting by blue smoke!
