02 sensor headache

After reading of everyone's woes I was expecting the worst. Hit them with PB blaster the night before. They came right out. Toughest part feeding the wires from the downstream sensors up to the top of the engine.

I live about 5-10 miles from Menlo Park (I'm in Redwood Shores). I've had no problems at all with the O2 sensors either (or just about any other fasteners on all of my other cars, vs. the stories I read on these forums). No PBBlaster, no prep, no 45* sockets (nice, BTW), no nothing special at all.

I will guess it is not just a matter of luck. The incredibly high taxes we pay out here are obviously used to fund a top secret government program to keep all automotive fasteners rust free. You heard it here first. (seriously, it is the climate and good roads, no salt - which we do all pay for out here, directly or not)
