RE: o2 sensors
That describes the situation fairly accurately. Driver's side is the problem, passenger side has enough clearance. Soak, heat, soak, heat, repeat often. Forget the O2 socket, crows foot or a open end wrench, they're not strong enough. You might get away with a bent, long handle box end wrench with a presuader pipe. I did this: Cut off the top of the O2 sensors using a One Sided Hacksaw thing. If you can get 1/3 the way through w/o quiting, you can bust the rest off using some pliers. A short 6 point hex socket will now fit over it, and using a swivel pull bar and persuader pipe, you can wail on it. Don't forget lots of anti-seize compound when you re-install.. this will only happen one time! IMO, the real PITA is replacing that leaking EGR Tube. I could write a book on that one.
Why the heck do they make 12 point sockets anyway???
